How many blisters on your fingers indicate hand, foot, and mouth disease?

Patient's question:

Saturday had a fever, accompanied by a little cough, and it went down after taking medicine. The doctor gave an intravenous drip and prescribed some antibiotics and cold medicine, but by Tuesday, a few small blisters were found on the hands.

Doctor's answer:

In your case, it may be caused by a viral infection, and there is no specific treatment available. The main approach is still general supportive therapy and symptomatic treatment. Antibiotics or sulfonamides are ineffective. Some antiviral drugs, such as idoxuridine, ara-A (cytarabine), and acyclovir, may have certain effects on herpesvirus infections. Interferon is a broad-spectrum antiviral drug that inhibits both DNA and RNA viruses. Triazofuridine may have an inhibitory effect on certain viruses, such as the virus causing hemorrhagic fever with renal syndrome. Amantadine can prevent influenza. Traditional Chinese medicine may have some efficacy in alleviating symptoms of certain viral diseases and shortening the course of the illness.
