Common for children to get hfmd after going school? My lo just started school and catch the disease just after 2 weeks

It is rather common as young children's immunity is low. In addition to this point, poor environment hygiene, poor hand hygiene and isolating infectious cases are also contributing factors. Unnecessary exposure of known cases to unaffected children should also be avoided. Besides these, be it in childcare or public, every parent should practice sole diligence in keeping the sick child at home to avoid the spread of virus though contact.
