Outbreak 1 (MWI/FMD/2017/1): Mthumba Dip Tank, T/A Katunga, Chikwawa<br>
Date of start of the outbreak: 24 Aug 2017<br>
Outbreak status: continuing (or date resolved not provided)<br>
Epidemiological unit: other<br>
Total animals affected<br>
Species / Susceptible / Cases / Deaths / Killed and disposed of / Slaughtered<br>
Cattle / 30 000 / 26 / 0 / 0 / 0<br>
<br>
Affected population: The affected population is under a communal grazing system and in very close proximity to buffaloes that are in Lengwe National Park. There is occasional mixing of cattle and buffaloes, especially when the buffaloes stray out of the park and graze with cattle. The population is within the locality that is strategically vaccinated against FMD using a trivalent FMD vaccine containing the 3 SAT strains (SAT1, SAT2 and SAT3).<br>

Outbreak statistics [rates apparent, expressed as percentages]<br>
Species / Morbidity rate / Mortality rate / Case fatality rate / Proportion susceptible animals lost*<br>
Cattle / 0.09 / 0 / 0 / 0<br>
*Removed from the susceptible population through death, destruction, and/or slaughter<br>
<br>
Epidemiology<br>
Source of the outbreak(s) or origin of infection: Unknown or inconclusive<br>
Epidemiological comments: There is a strong suspicion that it originated from buffaloes found in Lengwe National Park, which occasionally mix with cattle in the area.<br>
<br>
Control measures<br>
Measures applied: movement control inside the country, surveillance outside containment and/or protection zone, surveillance within containment and/or protection zone, quarantine, control of wildlife reservoirs, disinfection, process to inactivate the pathogenic agent in products or by-products, vaccination permitted (if a vaccine exists), no treatment of affected animals<br>
Measures to be applied: vaccination in response to the outbreak(s), screening, traceability, official destruction of animal products<br>
