As an example of how opportunistic & pernicious the coronavirus is, eight sailors out of 5,000 on the USS Theodore Roosevelt aircraft carrier deployed in the South Pacific have tested positive for coronavirus. Fifteen days ago, the ship made a port call to Da Nang, Vietnam but no port calls since. However aircraft have been coming & going off the ship to deliver personnel & supplies.
This isn’t just a matter of doing the forensics on one ship. The US Navy has over 285 ships, including 11 aircraft carriers, in a constant state of deployment, all of them making port calls around the world. That should answer the question of whether armies can be carriers of coronavirus.
