KANSAS CITY, Mo. — Kansas City Royals All-Star pitcher Kelvin Herrera and right fielder Alex Rios have been diagnosed with chickenpox, raising concerns that others on the American League Central-leading team may have been exposed.

Team officials said Tuesday that Herrera and Rios likely will miss a couple of weeks as the season wraps up. Both players were sent home from Tampa Bay after experiencing symptoms over the weekend.

The Royals have reached out to players, coaches and their families to determine whether anyone else has had chickenpox or might be at risk.

The disease is highly contagious, spread through the air via coughing or sneezing and sometimes by touching. It causes a blister-like rash, fever and tiredness. It can be serious for people with weakened immune systems.
