What's worrisome is that some people are testing positive again, after being diagnosed as positive. Crew on the CVN-71 Roosevelt have tested positive, been quarantined for 14 days, then tested negative twice (two days apart), but then still testing positive a few days later.[1]
The possible scenarios for this I can come up with are:
1. No immunity after initial infection
2. Bad test methodology (contamination etc)
3. Bad tests. The article doesn't mention the test type, so perhaps they were initially misdiagnosed (false positive), then infected upon return to the ship. The implication from this would be that the virus is still prevalent in the crew on board the Roosevelt...

There are no confirmed cases of reinfection and many thousands of people on 'front line' jobs who have recovered form the disease, returned to work and never been reinfected. In a study done on monkeys, scientists were unable to achieve reinfection.
