Study reveals coronavirus can survive for almost a month on phones, banknotes

Study reveals coronavirus can survive for almost a month on phones, banknotes”

The patient tested positive for the virus in April and suffered from mild symptoms, including a cough and nausea. A month later, he began feeling poorly again. At the same time, there was an outbreak where one of his parents, also an essential worker, was employed.

The 25-year-old man's reinfection is the second confirmed case in which the patient had more severe symptoms the second time. On June 5, he went to see a doctor who found his oxygen levels dangerously low and had him hospitalized. The man had a negative PCR test in July after the first infection, and genome sequencing in May and August showed two different strains of SARS-CoV-2.

However, researchers noted that the findings do not prove that people have been infected through breathing the virus in through the air or by touching contaminated surfaces. He is the fifth person in the world to get reinfected with the coronavirus. Lingering symptoms included fatigue and shortness of breath.

Reinfections imply so-called herd immunity can not be obtained just through natural infection. "It's possible that the vast majority of people are completely protected from reinfection, but we're not measuring them, because they're not coming to the hospital".

"There are still many unknowns", Mark Pandori, the director of the Nevada State Public Health Laboratory who led the study into the American case, told Bloomberg.

"You're not invulnerable to this", Pandori said. "In fact, you could get it worse the second time".

However, since many cases are asymptomatic and therefore unlikely to have tested positive initially, it may be impossible to know if a given Covid-19 case is the first or second infection. It raises questions about how long people are protected after being infected with the coronavirus that causes the disease, and potentially how protective a vaccine might be. "However, given the (more than) 40 million cases worldwide, these small examples of reinfection are tiny and should not deter efforts to develop vaccines". Her immune system was compromised due to the cell-depleting therapy she received, the researchers at Maastricht University Medical Center in the Netherlands wrote in a paper accepted for publication in the journal Clinical Infectious Diseases. The virus was then extracted after a period of time and tested to determine how infectious it was.
