Understanding animal epidemic foci, epidemic zones, epidemic-threatened zones, buffer zones, and animal epidemic-free zones<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">In practice, many farmers use the general term \u201cdisease outbreak area\u201d to describe locations where an animal disease is occurring. However, in a legal context, Vietnam\u2019s Law on Animal Health uses the term <\/span><b>\u201cepidemic zone.\u201d<\/b><span style=\"font-weight: 400;\"> Understanding the differences between these related concepts can help avoid incorrect assessments of disease status and farm risk.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>animal epidemic focus<\/b><span style=\"font-weight: 400;\"> is a place where an infectious animal disease included in the list of diseases subject to epidemic announcement is present.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>epidemic zone<\/b><span style=\"font-weight: 400;\"> is a zone where an animal epidemic focus exists or where a new infectious pathogen has been identified by the competent animal health management agency.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>epidemic-threatened zone<\/b><span style=\"font-weight: 400;\"> is a zone surrounding an epidemic zone or adjacent to an epidemic zone of a neighbouring country, as identified by the competent animal health management agency. Such areas require monitoring and appropriate disease prevention and control measures in accordance with guidance from the relevant authorities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A <\/span><b>buffer zone<\/b><span style=\"font-weight: 400;\"> is a zone surrounding an epidemic-threatened zone that has been identified by the competent animal health management agency.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>animal epidemic-free zone<\/b><span style=\"font-weight: 400;\"> is an area that meets applicable requirements for disease prevention, disease surveillance, veterinary control, and other relevant conditions, and has been officially recognised by the competent authority.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It is important to note that an <\/span><b>animal epidemic-free zone is not simply an area where no outbreak is currently being reported<\/b><span style=\"font-weight: 400;\">. An area is considered epidemic-free only when it meets the required conditions and has been officially recognised under current regulations.<\/span><\/p>\n<h3><b>1.2. Why checking disease outbreak areas matters in practice<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Checking disease information is not only about staying updated. It can also support risk assessment before important decisions in livestock production and trading activities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For <\/span><b>farm owners<\/b><span style=\"font-weight: 400;\">, local disease information can help:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assess potential risks before sourcing breeding stock from a particular area, together with quarantine documents, herd health status, and other relevant information.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Determine when biosecurity measures and herd or flock health monitoring may need to be strengthened.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Proactively check current requirements before selling or transporting animals.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">For <\/span><b>slaughterhouses and livestock buyers<\/b><span style=\"font-weight: 400;\">, disease information provides additional epidemiological context about the animals\u2019 area of origin. Verification of animal origin, quarantine documentation, and other required records still needs to be conducted separately in accordance with applicable regulations.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Farmers should not wait until they hear reports of an outbreak before checking official information. Disease conditions can change over time, so the latest data should be reviewed before important activities such as introducing new animals, moving animals off the farm, or transporting livestock between locations.<\/span><\/p>\n<h2><b>2. Official sources for checking animal disease outbreak areas in Vietnam<\/b><\/h2>\n<h3><b>2.1. VAHIS<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">VAHIS, the <\/span><b>Viet Nam Animal Health Information System<\/b><span style=\"font-weight: 400;\">, is used for reporting, compiling, and managing information on animal diseases in Vietnam.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Depending on the information made publicly available at a given time, users may be able to review data such as:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Disease situation and number of outbreaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Disease type.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Affected animal groups.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Date of detection or reporting.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Location of outbreaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Publicly available disease statistics.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">VAHIS also includes professional reporting and management functions for competent authorities. These features may require a user account, and not all operational data is necessarily available to the general public.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When using VAHIS, users should check the reporting period, latest update, disease type, and geographical area displayed. Filters and publicly accessible functions may change as the system is updated, so users should not assume that the interface and available functions will always remain the same.<\/span><\/p>\n<h3><b>2.2.

Distinguishing official sources from media and social media reports<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Information about animal disease outbreaks often spreads quickly through news outlets and social media. However, these sources may not always reflect the complete legal status or the latest developments in the affected area.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For example, a news article may report an outbreak when it is first detected but may not be updated later when the control area changes or when the competent authority officially declares the outbreak over.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For this reason, information from news outlets and social media should be treated as a <\/span><b>signal for further verification<\/b><span style=\"font-weight: 400;\">, rather than the sole basis for decisions on livestock introduction, animal movements, transportation, or changes to disease prevention measures.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For important decisions, farmers and businesses should cross-check official sources and contact the competent local veterinary authority when confirmation is required.<\/span><\/p>\n<h2><b>3.

Identify the information you need<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Before accessing an information system, clearly identify three factors:<\/span><\/p>\n<p><b>Location to be checked<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Identify the province, district, commune, or other relevant area where the farm is located, where breeding stock will be sourced, or where animals are expected to be moved to or from.<\/span><\/p>\n<p><b>Disease or animal group<\/b><\/p>\n<p><span style=\"font-weight: 400;\">For example:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">African swine fever (ASF) in pigs.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Avian influenza in chickens, ducks, and other relevant poultry species.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lumpy skin disease in cattle and buffaloes.<\/span><\/li>\n<\/ul>\n<p><b>Time period<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Determine whether you need to check the current disease situation or review outbreak history over a particular period.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The appropriate period depends on the disease, its epidemiological characteristics, and the purpose of the assessment. A single fixed time frame should not be assumed to be appropriate for every animal disease.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Defining these factors in advance makes the search more focused and reduces the risk of interpreting irrelevant information.<\/span><\/p>\n<h3><b>3.2. Steps for checking an official system or epidemiological map<\/b><\/h3>\n<p><b>Step 1: Access an official information source<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Prioritise VAHIS, official information channels of the Department of Animal Health and Production, or information published by local livestock and veterinary authorities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Avoid using links from unknown sources circulated on social media, as they may lead to unofficial pages, outdated data, or content that has subsequently changed.<\/span><\/p>\n<p><b>Step 2: Select the location<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If the system provides geographical filters, select the relevant province, district, commune, or area.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Always check the geographical scope represented by the data. An outbreak reported in one commune or district does not automatically represent the disease status of an entire province.<\/span><\/p>\n<p><b>Step 3: Filter by disease or animal group<\/b><\/p>\n<p><span style=\"font-weight: 400;\">If filtering is available, select the disease or livestock group you need to review.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This is important because several different diseases may be reported in the same area and may affect different livestock populations.<\/span><\/p>\n<p><b>Step 4: Review the results and save the information if necessary<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Once relevant data has been identified, check the disease status, latest update, disease type, geographical coverage, and reporting period displayed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the interface allows data to be exported or downloaded, the results may be retained for internal monitoring. If this function is unavailable, record the date of the search and the information source for future reference.<\/span><\/p>\n<h3><b>3.3. Reviewing disease history for long-term risk assessment<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A status indicating that \u201cno outbreak is currently reported\u201d does not mean that an area is free from epidemiological risk.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When assessing breeding stock sources, planning livestock introduction, or expanding a farm, it is useful to review the area\u2019s disease history rather than relying solely on its status at the time of the search.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When reviewing disease history, consider:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Frequency of outbreaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Diseases previously reported.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Time intervals between outbreaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Geographical extent of previous outbreaks.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Progression and duration of previous control efforts.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The review period should be selected according to the disease, the purpose of the assessment, and guidance from competent authorities. For major decisions such as introducing large numbers of animals or investing in farm expansion, historical data should be considered together with quarantine information, current local conditions, and appropriate professional advice.<\/span><\/p>\n<h2><b>4. How to interpret information on disease maps and data tables<\/b><\/h2>\n<h3><b>4.1. Important data fields<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">When reviewing search results, several types of information deserve particular attention.<\/span><\/p>\n<p><b>Disease status<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The status displayed may vary depending on the data source and classification system. Examples may include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Active outbreak or outbreak currently being reported.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Disease control measures currently being applied.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Outbreak officially declared over by the competent authority.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Do not assume that an outbreak has ended simply because no new cases have been reported for several days. The legal status of the area and the conditions for lifting disease control measures should be determined based on information from the competent authority.<\/span><\/p>\n<p><b>Date of detection and date an outbreak is declared over<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The date of detection helps users understand which period the information relates to and assess how current the data is.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Where information on an official declaration ending the outbreak is available, this is an important milestone for assessing the legal status of the area. However, when planning animal transport or trade, current requirements should still be confirmed with the relevant local veterinary authority.<\/span><\/p>\n<p><b>Disease and affected animal species<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Identify exactly which disease is being reported and which animal group is affected in order to determine its relevance to the farm\u2019s operations.<\/span><\/p>\n<p><b>Number of outbreaks and scale of impact<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The number of outbreaks and the number of animals affected, dead, or culled \u2014 where such information is publicly available \u2014 can provide context about the scale of an outbreak.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, disease risk should not be assessed solely by the number of reported outbreaks. The characteristics of the pathogen, geographical coverage, livestock density, and disease control measures in place should also be considered.<\/span><\/p>\n<h3><b>4.2. How to interpret colours and symbols on disease maps<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Epidemiological maps may use colours, icons, or other symbols to distinguish between data categories, geographical areas, or disease status.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some maps may use different colours to represent different types of information. However, users should <\/span><b>not automatically assume that red always means an active outbreak, yellow means a warning, and green means safe<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Colour conventions may vary between systems and between different versions of the same map. Before interpreting the data, check the legend on the specific map being used to understand the meaning of each colour and symbol.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the system allows users to change the reporting period, also check which time frame is currently displayed to avoid confusing historical data with the current situation.<\/span><\/p>\n<h3><b>4.3. Disease alert levels and their practical implications<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Users should not assume that every animal disease information system in Vietnam applies a single standardised \u201cdisease alert level\u201d scale.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In practice, the measures applied depend on the disease, geographical extent of the outbreak, epidemiological situation, and decisions of the competent authority at the relevant time.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Depending on the situation, disease prevention and control measures may include:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Enhanced disease surveillance.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Implementation or strengthening of quarantine measures in accordance with applicable regulations.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Controls on the transport of animals and animal products.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Hygiene, disinfection, biosecurity, or other disease prevention and control measures recommended by competent authorities.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Local disease conditions may affect quarantine requirements, animal movements, and sales plans. Before transporting animals, both the area of origin and destination should therefore be checked, and current requirements should be confirmed with the competent authority when necessary.<\/span><\/p>\n<h3><b>4.4.

Professional decisions should follow veterinary guidance, vaccine manufacturer recommendations, and current regulations.<\/span><\/p>\n<h2><b>5. Common mistakes when checking disease outbreak areas and how to avoid them<\/b><\/h2>\n<h3><b>5.1. Selecting the wrong location, disease, or time period<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">One common mistake is reviewing data only at the provincial level when the relevant information applies to a specific district or commune.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This can lead to an incorrect assessment of the geographical extent of an outbreak.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Likewise, selecting the wrong disease or animal group can produce results that are not relevant to the risk being assessed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Users should also check the reporting period displayed. Some systems may default to a particular time range. Without reviewing this carefully, users may confuse historical data with the current situation or overlook previous outbreaks.<\/span><\/p>\n<h3><b>5.2. Ignoring disease history and the latest update<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Relying only on a current status showing \u201cno outbreak reported\u201d is not sufficient to assess the full disease risk of an area.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For large-scale livestock introduction or long-term investment plans, reviewing historical disease information can help determine whether relevant diseases have previously occurred or re-emerged in the area.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The latest data update is also important. During a rapidly evolving outbreak, information that has not yet been updated may not fully reflect current conditions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Each time information is checked, review:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The latest update date.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The reporting period displayed.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The time frame covered.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The disease or outbreak status shown.<\/span><\/li>\n<\/ul>\n<h3><b>5.3. What to do when online information differs from the local situation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">In some situations, farmers may receive information about suspected disease signs or a newly detected outbreak from local veterinary officers or other local sources before the online system has been updated.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This may result from the time required for verification, reporting, and data consolidation.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In such cases, contact the local veterinary authority directly for confirmation. If animals show unusual signs or local authorities have issued a warning, appropriate biosecurity measures should be strengthened and guidance from the veterinary authority should be followed rather than waiting solely for the online system to be updated.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Conversely, if an online system still shows an outbreak while farmers have been told that the situation is under control, the official status should be confirmed before transporting animals, introducing new livestock, or conducting trade.<\/span><\/p>\n<h2><b>6. Frequently asked questions about animal disease outbreak information<\/b><\/h2>\n<figure id=\"attachment_20131\" aria-describedby=\"caption-attachment-20131\" style=\"width: 817px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-20131\" src=\"https:\/\/www.vietstock.org\/wp-content\/uploads\/2026\/09\/istockphoto-2177269923-612x612-1.jpg\" alt=\"Illustration of monitoring and checking animal disease outbreak information in pig populations.\" width=\"827\" height=\"551\" srcset=\"https:\/\/www.vietstock.org\/wp-content\/uploads\/2026\/09\/istockphoto-2177269923-612x612-1.jpg 612w, https:\/\/www.vietstock.org\/wp-content\/uploads\/2026\/09\/istockphoto-2177269923-612x612-1-300x200.jpg 300w\" sizes=\"(max-width: 827px) 100vw, 827px\" \/><figcaption id=\"caption-attachment-20131\" class=\"wp-caption-text\">Understanding epidemic zones, animal epidemic foci, and animal epidemic-free zones helps farmers interpret disease information more accurately.<\/figcaption><\/figure>\n<h3><b>6.1. What is the difference between an epidemic zone, an animal epidemic focus, and an animal epidemic-free zone?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">In general usage, a \u201cdisease outbreak area\u201d often refers to a location where an outbreak is occurring. However, Vietnam\u2019s Law on Animal Health uses the legal term <\/span><b>\u201cepidemic zone.\u201d<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>animal epidemic focus<\/b><span style=\"font-weight: 400;\"> is a place where an infectious animal disease included in the list of diseases subject to epidemic announcement is present.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>epidemic zone<\/b><span style=\"font-weight: 400;\"> is a zone where an animal epidemic focus exists or where a new infectious pathogen has been identified by the competent animal health management agency.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An <\/span><b>animal epidemic-free zone<\/b><span style=\"font-weight: 400;\"> is an area that meets applicable regulatory requirements and has been officially recognised by the competent authority.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Therefore, an area where no disease is currently reported is not automatically an officially recognised animal epidemic-free zone.<\/span><\/p>\n<h3><b>6.2. Which sources should be prioritised when checking disease outbreak areas?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Farmers should prioritise VAHIS, official information channels of the Department of Animal Health and Production, and information from local livestock and veterinary authorities.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For conditions in a specific commune, district, or production area, information from local veterinary authorities is particularly important.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If an immediate decision is required regarding livestock introduction, transport, or herd management, the relevant local veterinary authority should be contacted directly for confirmation rather than relying solely on online information.<\/span><\/p>\n<h3><b>6.3. How often is animal disease outbreak information updated?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Update frequency depends on the system, type of data, and reporting procedures used by the relevant authority.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During rapidly evolving disease situations, information may change frequently. Users should therefore not assume that every system follows a fixed update schedule. Instead, check the latest update date or reporting period shown by the source at the time of the search.<\/span><\/p>\n<h3><b>6.4. What should farmers do if their farm area is officially declared an epidemic zone?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">First, contact the local veterinary authority to determine the geographical scope of the declaration and the disease prevention and control measures currently in force.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While awaiting specific guidance, or while disease control measures are being applied, farmers may:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Limit unnecessary livestock movements and check current requirements before transporting animals.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Strengthen controls over people, vehicles, tools, and supplies entering and leaving the farm.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Apply appropriate cleaning, disinfection, and biosecurity measures.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Closely monitor herd or flock health.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Notify the veterinary authority if animals show unusual signs or are suspected of having an infectious disease.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Decisions involving vaccination, treatment, animal handling, or culling should be made in accordance with guidance from competent authorities, veterinarians, and applicable regulations.<\/span><\/p>\n<h3><b>6.5. Who should be contacted if online information differs from the actual local situation?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Contact the competent local livestock and veterinary authority or the responsible veterinary contact for the area where the farm operates.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These authorities can help confirm the current situation, geographical extent of the outbreak, and control measures being applied.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If additional national-level information is required, users can also refer to the official information channels of the Department of Animal Health and Production.<\/span><\/p>\n<h2><b>Connecting Epidemiological Data with Risk Management at VIETSTOCK 2026<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Checking epidemic zones helps farmers and businesses make more informed decisions about livestock introduction and movement, animal transport, breeding stock sourcing, and the strengthening of biosecurity measures. However, disease data is only useful when it is interpreted correctly in relation to location, disease type, reporting date, and outbreak status, and when necessary, cross-checked with the competent veterinary authority.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At <\/span><b>VIETSTOCK 2026 \u2013 Vietnam\u2019s Premier International Feed, Livestock &amp; Meat Industry Show<\/b><span style=\"font-weight: 400;\">, participants can go beyond simply identifying \u201cwhere an outbreak is occurring\u201d and explore how epidemiological information can support herd and farm risk management.
