Is is possible to contract HAV by holding the doorknobs ,I did wash my hands before having food that day but I used my wallet without washing my hands & the next day prior to when I had a meal in the restaurant I used my wallet & I didn't wash my hands before eating. is it possible that HAV might have been there on my wallet for more than 24 hours?
my another question is that is HAV fatal?
does it damage the liver for ever or liver gets better again on its own?
what are the tests available to detect HAV & what is the window period of those tests?
