Guarito covid è contagioso

Sembra che i pazienti guariti da Covid che dopo qualche tempo tornano di nuovo positivi al tampone non siano infettivi.

Quelle rilevate dal tampone, dunque, sarebbero particelle virali morte. Dopo il primo report di fine aprile la Korea del Sud ha continuato a raccogliere e analizzare i campioni del monitoraggio attivo dei guariti da Covid Come si spiega? Via: Wired. Covid, come stanno le persone guarite dal coronavirus dopo la terapia intesiva? Tutti in fila per il test sierologico, ma ne vale veramente la pena?

Cosa hanno scoperto dalla loro analisi di oltre 80 indagini diverse? Che la carica virale raggiunge il suo picco nella gola e nel naso, principale fonte di trasmissione, molto presto, in particolare dal primo giorno dei sintomi al quinto.

Anche nelle persone con sintomi lievi o medi. Questo in linea generale. In ogni caso dopo i nove giorni dal primi problemi non si sono riscontrate tracce virali attive.

E informare le persone con cui siamo stati in contatto almeno nei tre giorni precedenti, per consentire loro di fare eventualmente lo stesso o, se senza sintomi, sottoporsi a un tampone di controllo per togliersi ogni dubbio. Secondo le scienziate gli ostacoli a un isolamento come si deve sono molti: dai figli piccoli da accudire al basso salario, o al lavoro autonomo privo di malattia retribuita che spinge molti a tenere duro e magari soprassedere sui sintomi, fino alle ristrettezze abitative.

Per lo studio sono stati seguiti quattro operatori sanitari tra i 30 e i 36 anni contagiati dal nuovo coronavirus e curati all'Ospedale Universitario Zhongnan, a Wuhan, tra il 1 gennaio e il 15 febbraio. Con la scomparsa dei sintomi e due test negativi consecutivi, i quattro sono stati dimessi e invitati a una quarantena domestica di altri cinque giorni.

Come prassi, sono stati testati di nuovo per il coronavirus tra il quinto e il tredicesimo giorno post dimissioni: a sorpresa, tutti questi test di follow-up sono risultati positivi al virus.

Per i ricercatori, questo sembra suggerire che almeno una parte dei pazienti guariti dal COVID resti per qualche tempo portatrice del virus. Lieve ripresa. Una diversa situazione.

Scopri il mondo Focus. Follow us.Over the past year, as the health authorities have tried to curb the Covid pandemic, researchers have trained their scientific attention on a variety of potentially risky environments: places where large groups of people gather and the novel coronavirus has ample opportunity to spread.

They have swabbed surfaces on cruise ships, tracked case numbers in gyms, sampled ventilation units in hospitals, mapped seating arrangements in restaurants and modeled boarding procedures in airplanes.

They have paid less attention to another everyday environment: the car. A typical car, of course, does not carry nearly enough people to host a traditional super-spreader event. But cars come with risks of their own; they are small, tightly sealed spaces that make social distancing impossible and trap the tiny, airborne particles, or aerosols, that can transmit the coronavirus. In a new study, Dr.

Mathai and three colleagues at Brown University — Asimanshu Das, Jeffrey Bailey and Kenneth Breuer — used computer simulations to map how virus-laden airborne particles might flow through the inside of a car. Their results, published in early January in Science Advance ssuggest that opening certain windows can create air currents that could help keep both riders and drivers safe from infectious diseases like Covid To conduct the study, the research team employed what are known as computational fluid dynamic simulations.

Engineers commonly use these kinds of computer simulationswhich model how gases or liquids move, to create racecars with lower drag, for instance, or airplanes with better lift. The team simulated a car loosely based on a Toyota Prius driving at 50 miles per hour, with two occupants: a driver in the front left seat and a single passenger in the back righta seating arrangement that is common in taxis and ride shares and that maximizes social distancing.

In their initial analysis, the researchers found that the way the air flows around the outside of the moving car creates a pressure gradient inside the car, with the air pressure in the front slightly lower than the air pressure in the back. As a result, air circulating inside the cabin tends to flow from the back of the car to the front. Next, they modeled the interior air flow — and the movement of simulated aerosols — when different combinations of windows were open or closed.

The air-conditioning was on in all scenarios. Unsurprisingly, they found that the ventilation rate was lowest when all four windows were closed. When all the windows were completely open, on the other hand, ventilation rates soared, and the influx of fresh air flushed many of the airborne particles out of the car; just 0. The results jibe with public health guidelines that recommend opening windows to reduce the spread of the novel coronavirus in enclosed spaces.

Chan School of Public Health. In an op-ed last year, he highlighted the danger that cars could pose for coronavirus transmission, and the potential benefits of opening the windows. Allen said. Mathai and his colleagues also modeled several other options.

They found that while the most intuitive-seeming solution — having the driver and the passenger each roll down their own windows — was better than keeping all the windows closed, an even better strategy was to open the windows that are opposite each occupant. That configuration allows fresh air to flow in through the back left window and out through the front right window and helps create a barrier between the driver and the passenger.

Mathai said. Richard Corsi, an air quality expert at Portland State University, praised the new study. Corsi, a co-author of the op-ed with Dr. Allen last year, has since developed his own model of the inhalation of coronavirus aerosols in various situations.

His results, which have not yet been published, suggest that a minute car ride with someone who is emitting infectious coronavirus particles can be much riskier than sharing a classroom or a restaurant with that person for more than an hour. In a follow-up study, which has not yet been published, Dr. Mathai found that opening the windows halfway seemed to provide about the same benefit as opening them fully, while cracking them just one-quarter of the way open was less effective.

Mathai said that the general findings would most likely hold for many four-door, five-seat cars, not just the Prius.ForzaNapoliSempre pic. Copyright - Napoli Magazine Tutti i diritti riservati.
