People with a weakened immune system, kidney failure, liver damage and those who are being treated for cancer or have recently undergone organ transplantation are at risk of reinfection by the coronavirus infection. This is the opinion of American scientists.
Researchers from the University of Texas Health Science Center at Houston, along with specialists from Vanderbilt University Medical Center in Nashville, analyzed an electronic database of US medical records and selected 23 patients who had re-infected with SARS-CoV-2, according to PCR tests.
The mean age of the patients was 64.5 years, and most had conditions like diabetes, hypertension or immune disorders. The vast majority were also obese and had bad habits such as smoking. The genomic analysis revealed that all cases had reinfection rather than an undercurrent of the original variant of the disease.
The scientists noted that 70 percent of patients were hospitalized both during the first episode of the disease and during the second. Thus, the experts suggested that reinfection is no easier than the first.
Those who have had a mild form of coronavirus may also be reinfected, the researchers emphasized, but their risk of a severe course of the disease is minimal. Due to this, the scientists noted, citizens who have had COVID-19 in a severe form should be extra vigilant and attentive to their health.
Earlier the neurologist of Russian gerontological scientific-clinical center Helen Mkhitaryan has named the factor increasing the risk of death from COVID-19. Alzheimer’s disease and other types of dementia worsen the course of coronavirus.
