What is hand, foot and mouth disease?

Hand, foot, and mouth disease is common in children under the age of 5, but anyone can get it.

The disease is not usually serious, but it is very contagious. It is spreading quickly in schools and daycare centers.

Your child may get painful mouth sores. These sores usually start as small red spots, often on the tongue and inside the mouth, that blister and can become painful.

Signs your child might find it painful to swallow: Not eating or drinking, drooling more than usual, only wanting to drink cold liquids.

The actress is currently filming the second season of HIMYF.

The series streams on Hulu.

She shares Mae and daughter Banks, three, with her husband Matthew Koma, 35.

She is also mother to son Luca, 10, whom she shares with ex-husband Mike Comrie.

Real Housewives of Orange County graduate Meghan King revealed earlier this month that all three of her children, twins Hart and Hayes, three, and daughter Aspen, five, who she shares with ex-husband Jim Edmonds, have the same virus like Mae have.

The Centers for Disease Control reports that HFMD is common in children under the age of five.

It is a contact disease that can be transmitted by hugging or kissing an infected person, and the infection can be transmitted by changing diapers and blowing your nose.

It occurs most often in summer and autumn.

And it usually clears up within seven to 10 days.

Adults can also contract the virus, but they often don’t show any symptoms, which allows them to unknowingly pass it on to others.
