My baby has hfmd, showed first symptoms on saturday, had contact with another baby who had hfmd last tuesday, how long will he be contagious? Thanks

One week +/ few days. Incubation for this is 3-7 days from aquiring the virus and becoming symptomatic. Hfmd is a viral disease that has to run its course; many doctors do not prescribe medicine for this illness. Infection in older children, adolescents, and adults is typically mild and lasts approximately 1 week, occasionally longer. Afterwards, the child is not contagious!
