If a flying squirrel dies within three days of biting a human, the flying squirrel is likely to be carrying rabies virus or plague. If the flying squirrel does not go to the local CDC for a rabies vaccine injection within 24 hours after being bitten, , there is a high probability of causing viral infection, thus endangering life safety.
Therefore, people bitten by flying squirrels should get rabies vaccine in time and clean the bitten area. If you bite and bleed, squeeze the blood out first and then wash it with soapy water. If the bite area becomes swollen after cleaning, you need to go to the hospital for examination and treatment.
