there is also a form of treatment that can be done once a person has been bitten. it needs to be done within 6 days of being bitten. there is no way to know whether someone is infected, until it's too late. treatment starts with washing the wound. this is done to reduce the number of virus particles that enter the body. often patients are given one dose of immunoglobulin and a certain number of vaccines, over a determined period of time, usually a month.
