LOS ANGELES (KABC) -- Four children in Southern California have been infected by enterovirus 68, a rare cold virus that has already affected children in 16 states, according to the California Department of health.
All four patients, who were between 2 and 13 years old, underwent intensive care and are expected to recover. None had traveled outside of California prior to getting sick.
Three cases were confirmed in San Diego County and one case in Ventura County. Health officials anticipate these as the first of many cases in the coming weeks.
"We are not surprised to find EV-D68 causing some illnesses in California given the apparent widespread nature of this virus in other parts of the country," said Dr. Ron Chapman, the health department's director.
Enterovirus 68, also known as EV-D68, causes respiratory illness and spreads through coughs, sneezes or contaminated surfaces. Symptoms include fever, runny nose, sneezing, cough and body aches. Those with asthma may find it hard to breathe.
Adults who have tested positive for the virus usually have only mild cold symptoms.
Dr. Gil Chavez said it's important to note that three of the four patients had asthma. He recommends children with respiratory issues stay up-to-date on their medications.
"Any asthmatic child that develops an infection that's not getting well quickly should really consult with their health care provider," Chavez said.
There is no specific treatment or vaccine for the virus.
State health officials are urging people wash their hands for 20 seconds; avoid touching their eyes, nose and mouth with unwashed hands; avoid kissing, hugging and sharing cups with those who are sick; and to disinfect frequently touched surfaces.
"The first couple days that you have cough and congestion are usually the most contagious, so staying home away from other kids is one of the best methods of not allowing that to spread," pediatrician Dr. Danelle Fisher said.
