The San Francisco International Airport has posted signs warning travelers about the spread of a relatively new disease called Middle East Respiratory Syndrome Coronavirus, or MERS virus.
The virus appears to be spreading among travelers, prompting SFO and other airports to post the signs, which describe the symptoms of MERS and recommend steps travelers can take to stay healthy.
The MERS virus first appeared in residents of Saudi Arabia in 2012, but cases have since been reported in Jordan, Qatar, the United Arab Emirates, Oman and Kuwait, according to the San Francisco Department of Public Health. The disease has spread to travelers and cases have also been identified in Europe, North Africa and the United States.
The airport signs list symptoms as fever, cough and shortness of breath, and ask that travelers who get sick within 14 days of visiting the Arabian Peninsula to contact a doctor.
