Covid-19 Patients who had tested negative may still have the infection and need to wait over a month before being retested to know whether they have cleared the virus, a new research has revealed.
The new discovery means that the virus and its symptoms are often no where near finished by the 10-day benchmark
The study also suggests that about one in five negative tests are false negatives, meaning many are still spreading the virus after testing negative without knowing it.
In fact, once patients do test negative, many patients report their symptoms — from aches to loss of smell to brain fog and affected mood — can last months longer.
“We think that this long-term damage may in part be due to vascular damage, kind of a footprint that the virus leaves even when it’s gone from the body,” Dr. William Li told CNN’s Chris Cuomo earlier this week, adding that researchers have seen the virus damaging blood vessels that connect the entire body.
And with so much still not known about the virus, Li said it isn’t clear when “long haul” patients will be back to the lives they had before.
