^ Hmmm ... 57 of 61 after 35 days at sea. And, "exhibiting symptoms". Even if the first tests were faulty, or if one or more picked it up on their way from the hotel to the ship, what was it doing? Recycling among the crew?![]()

I'm hoping that Argentina gets their epidemiologists involved. Fortunately, Argentina has a good healthcare system and they have been taking a realistic approach to the pandemic.
The pattern that often seems to happen with COVID-19 is that it takes about 2 weeks for those who are going to get really sick to get to the point where they seek medical assistance. The way this thing spreads on a ship is slow and exponential and because there's a large number of asymptomatic carriers (especially among young people), it can be a month before it gets completely out of control. We saw with the USS Theodore Roosevelt.
Here's a timeline for the USS TR:
- On 8-Mar, USS TR reported that several sailors had been exposed to coronavirus at an onshore hotel in Vietnam. Thirty-nine soldiers are placed in quarantine.
- On 24-Mar, 3 sailors go to sick bay reporting that they have lost their sense of smell. The medical officer sends them back to work instead of putting them in isolation. Three other sailors test positive and these 3 sailors had no contact with the 39 sailors in quarantine.
- On 25-Mar, 4 crew members with COVID-19 are airlifted off the ship.
- On 26-Mar, 33 crew members test positive for COVID-19.
- On 28-Mar, 46 crew members have COVID-19.
- On 29-Mar, the number of cases rises to 53.
- On 31-Mar, the number of cases is over 100.
- On 1-Apr, the Navy rents 4,000 hotel rooms in Guam and evacuates non-essential personnel from the ship.
- On 5-Apr, the number of cases is 155.
- On 7-Apr, the number of cases is 173.
- On 8-Apr, the number of cases is 416.
- On 11-Apr, the number of cases is 550.
- On 12-Apr, the number of cases is 585.
- On 13-Apr, an officer from the TR dies while in quarantine in Guam.
- On 17 April, seven crew members were in the hospital including one in intensive care.
- On 20-Apr, a review finds that a total of 678 crew members have tested positive and 3,904 have tested negative. About 60% of the people who tested positive did not have symptoms.
- On 5-Jun, the Navy declares the epidemic resolved and the USS TR departs Guam.
So, it took from 8-Mar to 24-Mar (17 days) for the first cases to be identified. It then took from 24-Mar when the first cases were identified until 20-Apr for it to spread to 678 people. That's 44 days from exposure (8-Mar to 20-Apr) to get to 678 cases. It was 28 days from first 3 cases (24-Mar) to get to 678 cases.
The Wikipedia entry for the USS TR epidemic has an interesting comment:
Sailors kept testing positive for the virus even after 14 days of isolation; some who tested positive had previously tested negative.
