WASHINGTON, May 12 (Xinhua) -- The second case of the deadly Middle East Respiratory Syndrome (MERS) that initially surfaced in Saudi Arabia in 2012 has been discovered in the United States, the Centers for Disease Control and Prevention (CDC) said Monday.
The CDC said that the case was "imported" and that it is investigating along with Florida Department of Health officials.
No more details were immediately available. A news conference about the case was scheduled for Monday afternoon, according to the CDC.
The first American diagnosed with the MERS virus, a male healthcare worker, was reported on May 2 and released last Friday. He is thought to have acquired the MERS virus in Saudi Arabia last month.
According to the Community Hospital in Munster, Indiana, the healthcare worker is now "considered to be fully recovered and has been cleared by health officials to come off of isolation and may travel, if necessary."
So far, there have been more than 400 confirmed cases of MERS infection in 12 countries with more than 100 deaths, and all reported cases have originated in six countries in the Arabian Peninsula.
Most of these people developed severe acute respiratory illness, with fever, cough, and shortness of breath. Doctors do not know where the virus came from or exactly how it spreads. There is no available vaccine or specific treatment recommended for the virus.
