Covid-19, having symptoms but negative buffer. When it happens and why

All the symptoms are there to indicate the presence of Covid. But the swab is negative, perhaps even if repeated several times. A phenomenon that is increasing and that is also reported by the Federation of the Order of Doctors (Fnomceo).

“In the presence of obvious symptoms, compatible with Covid, one must always consider oneself contagious, wear the Ffp2 mask and repeat the test after 24 hours”, he advises Fabrizio Pregliascovirologist and director of the Galeazzi hospital in Milan.
