I just recovered from a nasty virus that consisted of fever, vomitting, diarrhea, chills, swollen and inflamed tonsils, coughing and extreme tiredness. It last 2-3 days. My sister who lives with me now has the virus and I am taking care of her. I nanny a toddler. Is it possible that I could catch this virus again even though I just had it? Is it possible for me to pass the virus to the toddler I watch since I am taking care of my sister even though I am better? My concern is the toddler getting it from me passed on from my sister even though I am better but taking care of my sister with the virus.
