The armed forces have over 6,500 coronavirus cases at more than 150 bases in every state in the United States except Iowa, Indiana, Minnesota, and Montana, according to new data from the Defense Department.
Though the Pentagon continues to keep secret the number of coronavirus cases by military bases, Newsweek obtained a series of updated spreadsheets compiled by individual commands. National Guard forces in at least 20 states have also reported coronavirus cases.
Since Newsweek exclusively reported the spread of coronavirus in the U.S. military on April 9, four states—Connecticut, Idaho, Maine, Michigan—plus the District of Columbia have been added to the American map.
With the services reporting 6,568 cases of COVID-19 among uniformed, civilian, contractors and family members as of early Monday, this is the fourth week in a row where cases grew by roughly 1,000. The Navy’s 1,659 cases constitute the rightest of all the services, with 969 sailors aboard the USS Theodore Roosevelt now having been tested positive.
Last week the destroyer USS Kidd, operating on counter-drug missions in the eastern Pacific off the coast of Mexico, had an outbreak of coronavirus, with the Navy reporting 47 cases. Forty-one Navy ships and one Coast Guard cutter have reported cases of coronavirus, according to the internal documents, but only 15 ships have been public divulged.
The Army has 995 cases as of Monday, followed by the Air Force with 347―the lowest infection rate in the armed services―the Marine Corps with 304, and 792 National Guardsmen and women, about three–quarters Army National Guard and one-quarter Air National Guard. The largest land-based cluster in the military is at Ft. Jackson, South Carolina, where some 64 soldiers—most Army recruits in training—came down with the virus.
That outbreak led to a two-week suspension of basic military training, which the Army announced would be lifted after mitigation measures were put in place it its four basic training centers. Activity at the Army’s combat training centers—at National Training Center at Fort Irwin, California and the Joint Readiness Training Center at Fort Polk, Louisiana—is at a standstill while Army leaders determine how to safely amass soldiers who go there to conduct collective training in battalion- and brigade-sized elements. Army Chief of Staff Gen. James McConville calls it a “tactical pause.”
Twenty state National Guards report cases of coronavirus: Alabama, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Illinois, Louisiana, Maryland, Maine, Michigan, Nebraska, New Jersey, New York, Pennsylvania, Texas, Utah, Washington and Wisconsin. The National Guards in Guam and Puerto Rico also report cases.
More than 20 percent of all military cases have occurred overseas, the highest numbers in Germany and South Korea.
