Source of the outbreak(s) or origin of infection
  • Introduction of new live animals
  • Illegal movement of animals
  • Animals in transit
  • Contact with infected animal(s) at grazing/watering
Epidemiological comments Twenty sera samples collected were positive on ELISA 3ABC. The population at risk is in a communal grazing system. Illegal animal movement is the main source suspected for the introduction of infected animals to the area. Samples from Mzimba and Chitipa were sent to Botswana Vaccine Institute for serotyping and the results showed that Mzimba District has SAT 2 and Chitipa has type A with some traces of SAT types respectively. Spillover into the adjacent district for Mzimba (Kasungu) was included in the vaccinations. Vaccinations were instituted in April (primer 61,886) with trivalent SAT types 1, 2 and 3 and booster in May 2019 (37,906, still continuing). Additional cases observed in Chitipa (7) and Kasungu (32), which is bordering Mzimba. Note: This outbreak first reported with outbreaks in Chitipa is reported now as a separate event since it concerns a different serotype (SAT 2).
