Two US officials have told Reuters Monday that a survey conducted by the US Navy to determine the prevalence of the Corona virus on the aircraft carrier Theodore Roosevelt showed the presence of antibodies to the virus in about 60 percent of the sailors tested, indicating a much higher prevalence rate than previously thought.
The Navy and the US Centers for Disease Control and Prevention began testing in April to monitor the presence of specific antibodies that result from attacking the immune system and staying in the body for a period of time.
Tests had shown that more than 1,100 people on board the aircraft carrier had contracted the virus as of April, less than 25 percent of the crew.
Sailor died of the virus and a number of his colleagues were hospitalized. The officials, who spoke on condition of anonymity, said that about 400 volunteers had undergone antibody-related tests.
Theodore Roosevelt, which is one of the largest warships in the world, carries about 4,800 people.
