Declared cured on April 24, the patient – who suffers from previous respiratory diseases – tested positive for the coronavirus after a smear made at the Parini hospital in Aosta: she is now hospitalized and under treatment with supplemental oxygen. The person in charge of Infectious Diseases: “It cannot be reinfection because it has antibodies: it is a new positivity of a cured subject”
Declared cured of Covid-19 on April 24, a middle-aged woman from Valle d’Aosta tested positive for coronavirus. The patient, who had come to the Parini de Aosta hospital due to the worsening of her clinical condition, is now admitted to the center and undergoing supplemental oxygen therapy. Apparently, the woman already has previous respiratory diseases. New positivity for the virus emerged from the swab performed at the time of entry. “Probably,” explained the head of Infectious Diseases, Alberto Catania, “it is not a reactivation of the virus, but the patient still has some viral residues that have been found in the swab. It cannot be reinfection because he has antibodies: it is a new positivity of a cured subject “.
Primary: women are not necessarily contagious

“Up to 300 thousand tampons a day”, what the Crisanti plan provides
According to Catania, it is “a finding of positivity, which is not said to be contagious: it may be that they are only viral parts that have been found in the test. These are possible situations, in my opinion they are not contagious people”.
The differences with the two cases of reinfection already documented in the world

Covid tampons, everything you need to know: types, times and costs
The situation of women in Valle d’Aosta therefore seems different from the two cases of reinfection documented so far in the world. The first refers to a thirty-three-year-old from Hong Kong, who would be infected for the second time in Spain, and the second to a 25-year-old snow-capped man. For both tests carried out on the genetic material of the two different samples, the dynamics had been clarified: the second infection was caused by a different virus than the first infection. The two patients had similar symptoms, but the second infection was more severe. Two cases that seem to go against the hope of scientists studying the virus, that is, that post-Covid antibodies can give immunity even for several years.
