In asymptomatic patients, too, affects the lungs
Scientists say that the coronavirus is potentially dangerous even for healthy people that can move his feet.
To a disappointing conclusion was made by Japanese scientists after comparing the CT images in people with symptoms COVID-19 without them. After checking the images in 54% of the surveyed people who had contracted the coronavirus, but moved it asymptomatic, was struck by light. This is stated in the study presented at the RSNA website.
Analysis of medical data 104 people aged 25 to 93 years with an established method of RT-PCR diagnosis was conducted among passengers of a cruise ship DiamondPrincess, who at the beginning of the epidemic for a long time remained a major focus of SARS-Cov-2 after China. From 104 76 did not show any symptoms COVID-19, and the remaining 28 were recorded: temperature above 37.5, cough, shortness of breath and weakness.
Scientists compared images of computed tomography of the lungs of these two groups of patients and found pathological changes in each.
“People have no symptoms COVID-19 in 54% of cases were observed changes in the tissues of the lung,” said the scientists.
In the second group of pathological changes in the lungs were the most and amounted to 79%. They manifested by increased density of lung tissue and changes in the respiratory tract.
“In asymptomatic patients are often observed only changes the type of “frosted glass” (83%), while in people with the characteristic signs of the virus more often had foci of consolidation in the lungs – the so-called airless tissue,” explained the study authors.
While scientists can not explain the changes in the lungs of asymptomatic ill people. Previously, there had been similar cases of infection of middle East respiratory syndrome (MERS-CoV), nor when infection of severe acute respiratory syndrome (SARS-Cov).
Informed of yet another method of treatment that could effectively treat the seriously ill COVID-19 patients the Correspondent said the head of the scientific Department of intensive care and detoxification of the Institute of epidemiology and infectious diseases named gromashevskiy of NAMS of Ukraine Sergey Borschev.
