Hi @Me 3-5 days is the quick answer to your question - after catching the infection, symptoms can take 3-5 days to surface. That being said, patients with HFMD can transmit the infection to others for weeks, although transmission is rare after 1 week. This usually occurs through contact (with the fluid in blisters) or respiratory droplets from (coughing/sneezing). It can rarely also occur through contact with fecal material. HFMD is a common infection caused by several viruses that can have rare but severe consequences such as infection in the brain. If you are worried about possibly having caught this infection, do have a more in-depth consultation with a doctor at a clinic or using a teleconsultation app such as DoctorWorld.
