African Swine Fever in Meghalaya:
Earlier this month, the Government of Meghalaya had confirmed cases of the African Swine Fever (ASF) among pigs in the state. During a media briefing, deputy chief minister Prestone Tynsong informed that out of 73 mysterious pig death cases, 24 have been confirmed to be due to ASF. As for the other 49 deaths, samples have been collected and sent for further investigation.
The virus causes a hemorrhagic fever with high mortality rates in domestic pigs; some isolates can cause the death of animals as quickly as a week after infection. It almost always leads to death among pigs.
