Yeah, the thing about this virus is, you can be a spreader before you even have symptoms - with SARS, only those with symptoms were spreaders.
The Los Angeles County Health Department said the infected person was receiving medical treatment.
The department stated, There is no immediate threat to the general public, no special precautions are required, and people should not be excluded from activities based on their race, country of origin, or recent travel if they do not have symptoms of respiratory illness.
