The death count from the new SARS-like virus reached 30 Thursday with the death of three more people in Saudi Arabia, officials say. The new sickness, which the World Health Organization has called a “threat to the entire world,” is a respiratory infection that begins with a fever and cough. The most recent victims, who ranged in age from 24 to 60, are said to have died from a variety of ailments—one of them kidney failure. The Centers for Disease Control first warned the public of the new virus in March. It is believed to have originated in the Middle East.
