Orlando International Airport officials issued a statement Thursday about the deadly coronavirus, which has killed more than a dozen people and sickened hundreds of others since it was first reported last month in China. Rod Johnson, an airport spokesman, said the Centers for Disease Control and Prevention (CDC) plans to expand screening at airports this week, but OIA is not included in that grouping. As of Friday, the CDC is requiring screening of passengers arriving from Wuhan, China to Atlanta and Chicago O'Hare, Los Angeles International, San Francisco International and New York JFK. 'Since we do not have direct service from the affected regions in China, no additional measures are currently prescribed for our location,' Johnson said. 'However, we will continue to collaborate with health officials, monitor the situation for changes and will act accordingly.” Cases of the virus first surfaced in Wuhan, China, which has a population of more than 11 million. The first travel-related case in the U.S was announced Tuesday. A traveler who had been in central China landed at Seattle-Tacoma International Airport on an unidentified airline Jan. 15 and reported pneumonia-like symptoms to his doctor on Jan. 19. The Seattle-area resident did not take a nonstop flight between Wuhan and Seattle. So far, the virus has killed at least 17 people and sickened more than 600 others in China. Here are six things you should be aware of about the disease: 1. Coronavirus is actually a group of viruses that can cause a cold or something severe like Middle East respiratory syndrome, known as MERS, severe acute respiratory syndrome, known as SARS. The World Health Organization says symptoms are similar to pneumonia symptoms, CBS News reported. The initial symptoms include fever, cough, tightness of the chest and shortness of breath, The Associated Press reported. 2. Normally they’re transmitted from animal to humans, but 2019-nCoV is apparently able to be transmitted between humans. At least two people were infected that way, the BBC reported. But there are other coronaviruses in animal populations but have not been transmitted to humans, according to CBS News. 3. The World Health Organization is considering declaring a public health emergency, similar to what it did with Ebola and swine flu, the BBC reported. If the declaration happens, a coordinated international response will follow. 4. At least 15 medical workers are infected with 2019-nCoV and one is in critical condition. They are believed to have contracted the illness from treating patients who were kept in isolation, but that has not been confirmed, the BBC reported. 5. While the 2019-nCoV was traced back to a seafood market that also sells live animals in Wuhan, China last year, there are a few cases outside of China including Thailand, Japan, South Korea and Taiwan. Those cases are linked to the same area in China, the BBC reported. 6. People are taking measures to protect themselves from exposure to the virus. Medical-style face masks are sold out in China, the AP reported. Many people in Wuhan are wearing face coverings as they go about their day. The company that makes the anti-pollution masks, 3M was sold out of the mask online, the AP reported.
