Viral testing can produce false positive results, which may occur due to cross-reactivity or other factors, and should be confirmed with additional testing; in this case, Dr. Stephen Kornfeld, an oncologist who treated patients during a Hantavirus outbreak on the MV Hondius cruise ship, initially tested positive but was later confirmed negative through antibody testing, demonstrating the importance of confirmatory testing and the 42-day incubation period for Hantavirus.

🚨Doc on ship beats hantavirus false positive!🚨Added:
Imagine this, an American doctor boards a cruise ship for vacation and ends up fighting a viral outbreak. Three people around him die. He himself initially tests positive for Hantavirus, but then he doesn't. Dr. Stephen Kornfeld, the 69-year-old oncologist from Oregon, was on the MV Handius cruise ship when the Hantavirus outbreak hit. When the ship's doctor fell ill and was evacuated, Kornfeld stepped up and started treating sick passengers without knowing it's the Hantavirus, which certainly exposed him to this virus. Later, his own test came back faintly positive and he was taken to a biocontainment unit in Nebraska.
But here's the twist, two labs tested his sample, one negative, one faint positive. As a physician, I can tell you that's definitely not a diagnosis. Just yesterday, antibody testing confirmed a zero infection. The verdict, almost certainly a false positive. He was then cleared and moved to general quarantine.
In his words, it's a nice to be negative for Hantavirus, but he knows he's still in that 42-day incubation window. This shows the nuance of Hantavirus testing and risk and reality of false positives, but the risk to the public still very low. Follow me for more.
