KANSAS CITY, Mo. – Royals’ Outfielder Alex Rios and All-Star Reliever Kelvin Herrera both have chicken pox, which is a highly contagious virus.

The Royals said the two players could be out for at least two weeks.

Adults who come down with chicken pox are in for a rough ride.

Chicken pox spreads through coughing or sneezing and it spreads easily to people who've never had it or those who haven't had the chicken pox vaccine.

The virus causes a blister-like rash, itching, fatigue and fever. It can be more serious in adults than kids.  Adults are more likely to have complications such as pneumonia and encephalitis or inflammation of the brain.

It's 10 to 21 days after exposure before someone develops chicken pox. And a person with the virus can spread it before they know they have it.   They're contagious one to two days before the rash appears.

One dose of chicken pox vaccine is 85 percent effective, two doses, 98 percent effective.

Ball players from Latin American countries would be much less likely to have been vaccinated than those raised in the U.S.
