The Centers for Disease Control and Prevention (CDC) confirmed another case of the novel coronavirus (COVID-19) in the United States on Wednesday, bringing the country's total to 14. The four returned to quarantine at a nearby air station. A later test found one of those patients tested positive for the virus. She and three other people from the flight were subsequently hospitalized after showing possible symptoms of the disease that has killed more than 1,000 people, mostly in China.
UC San Diego Health confirmed that the individual is being treated by the hospital.
"The patient did not interact with the environment after leaving the hospital room", Galindo said. They will have been under quarantine for 14 days.
The CDC said the error occurred after it issued a negative finding Sunday on a large batch of specimens taken from people quarantined at the base.
"This is an accurate test", said Nancy Messonnier, who heads the coronavirus response at the CDC, in a briefing last week.
The infection was confirmed through a Wednesday night lab test. During a press conference Tuesday, officials said there has not been a known breach in the quarantine and there shouldn't be a concern among the general public.
The CDC is also re-examining whether 14 days is an appropriate duration for future coronavirus quarantines, as scientists learn more about the virus and how infectious it may be before patients show symptoms. The exact timing and occurrences on base - how long the infected evacuee was present and everything he or she did while there - has not yet been made public. They added that an additional patient has been sent to the hospital for evaluation. "We are taking all necessary measures and precautions to minimize any potential exposures as we care for both potential and confirmed COVID-19 cases".
The U.S. Centers for Disease Control and Prevention (CDC) said some of the kits sent to U.S. states and at least 30 countries produced "inconclusive" results due to a flawed component and the CDC planned to send replacement materials to make the kits work.
More than 1,100 people have died, almost all of them in China, where there are more than 44,000 confirmed cases.
"Patients and visitors can feel confident in making and keeping their appointments and using our services as usual", a university statement said.
