My husband has been sick fot 6 days. Flu symptoms. Originally we thought it could pass becuase some people at his work also had cold with same symptoms: body ache, cough, head ache, fever, chills. We took him to a minite clinic today and they basically said it sounds like hes got the flu and theres nothing they can do at this point. I am now coughing, and slept this entire afternoon. If i have gotten a virus in the last day or two can i or should i go get a flu shot??
