Ten passengers and crew members who said Thursday that flight 203 from Dubai to New York was positive for the flu and other common viruses, including colds, officials said Thursday.

According to the New York City Department of Health and Hygiene, testing for other viruses has not been conclusive and will be re-administered.

"The majority of tests have shown common viruses such as the flu and colds," said the agency in a statement on Thursday. "Unfortunately, the tests for the other viruses were inconclusive, which is not unusual in the tests, but that means we have to test some samples again today and hope to see results." complete in the afternoon. "

Eric Phillips, spokesman for New York Mayor Bill de Blasio, said via Twitter that the results of the tests on passengers and crew members hospitalized after the incident had found the flu. He stated that passengers and crew members will remain in the hospital as a precautionary measure until additional test results are available.

The Centers for Disease Control and Prevention said in a statement that patients were being treated by the hospital, including antivirals. Other passengers who develop symptoms should call their doctor. The CDC released Wednesday the majority of the 549 passengers and crew of the Emirates flight after their assessment.

As the influenza season approaches, the CDC recommends that people with the flu stay home and avoid traveling for at least 24 hours after the end of their fever. The agency also recommends the seasonal flu shot, preferably by the end of October.

Officials from the CDC and local, national and airport authorities met the Emirates plane when it landed Wednesday morning at John F. Kennedy International Airport after a long flight. Initial reports indicated that 100 passengers were sick. All passengers and crew members were assessed, with seven crew members and three hospitalized passengers. (The CDC puts the number of hospital patients at 11, which is higher than the number of airlines and other authorities.)

The plane was cleared by the authorities and returned to Emirates in time to make the return flight between New York and Dubai on Wednesday afternoon.

Then the medical detective work started to determine the cause.

Rapper Vanilla Ice was at the top level of the two-story Airbus A380 on Wednesday and described the scene when the plane landed like chaos.

Another passenger told USA TODAY that he had noticed that passengers were coughing and had other signs of illness. He said that the situation was not alarming until the plane began its descent and that the pilot told the passengers that there were sick passengers on board.
