(NBCNews.com) -- The United States has reported its first case of a new virus found in the Middle East, in a traveler from the region, the Centers for Disease Control and Prevention says.
The Middle East Respiratory Syndrome (MERS) virus has been spreading in Saudi Arabia and other countries.
The World Health Organization has expressed alarm about the increase in reports of MERS. WHO reports more than 250 confirmed cases and 93 deaths since the virus was identified in 2012. But Saudi Arabia alone has reported 371 cases, with 107 deaths.
Experts say it was only a matter of time before it came to the United States.
“In this interconnected world we live in, we expected MERS to make its way to the United States,” said Dr. Anne Schuchat, assistant surgeon general and director of CDC’s National Center for Immunizations and Respiratory Diseases. “We have been preparing since 2012 for this eventuality.”
But she says this first imported case poses only a low risk for the general public.
The CDC says the infected patient was a healthcare worker who traveled from Saudi Arabia to Indiana.
“On April 24, the patient traveled by plane from Saudi Arabia to London, then from London to Chicago.,” the CDC said. “The patient then took a bus from Chicago to Indiana. On the 27th, the patient began to experience signs of illness, including shortness of breath and coughing. The patient went to an emergency department on April 28th. Because of the patient’s symptoms and travel history, Indiana public health officials had him tested for MERS.”
The virus has infected people in Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Egypt, the United Arab Emirate, France, Germany, Greece, Italy, Britain, Tunisia, Malaysia and the Philippines. There’s no specific treatment, no cure and no vaccine for MERS.
Last week, WHO predicted a springtime surge in MERS cases.
MERS first showed up in 2012, when it killed an elderly Saudi man. It worries health experts because it’s related to severe acute respiratory syndrome, or SARS, which swept around the world in 2003, infecting around 8,000 people and killing close to 800 before it was stopped. Both conditions are caused by coronaviruses, members of a family of viruses that usually cause common cold symptoms and that infect a wide range of mammals.
The most recent research traces it to camels, although most cases seem to be spread from one person to another.
The virus can survive on surfaces, and might spread when people touch something contaminated. SARS appears to have spread that way, and many other viruses do, too.
CDC and WHO say the virus has spread many times in hospitals, dialysis centers and other healthcare facilities, so they are cautioning health workers to take special precautions.
“Infection prevention and control measures are critical to prevent the possible spread of MERS in health care facilities,” WHO says.
“Health care workers should be educated, trained and refreshed with skills on infection prevention and control. It is not always possible to identify patients with MERS early because some have mild or unusual symptoms. For this reason, it is important that health-care workers apply standard precautions consistently with all patients – regardless of their diagnosis – in all work practices all the time.”
