The SARS-CoV-2 virus circulates throughout the body, including into the brain and Continues for almost eight months, according to a study of tissue samples from 44 COVID-19 fatality autopsies.

The investigation found that all individuals who died from COVID-19 had no vaccinations. For SARS-CoV-2, 38 patient blood plasma samples tested positive, three blood samples tested negative and three blood samples were unavailable. The US National Institutes of Health (NIH) evaluated samples from autopsies between April 2020 and March 2021. According to the Mint, the neurological system, including the brain was comprehensively sampled in 11 patients for the study, published in Nature.

The adrenal gland, eye, brain, heart, lymph nodes and digestive tract are just a few of the organs from inside and outside the respiratory system from which the researchers were also able to isolate live SARS-CoV-2 virus. 45 percent of the 55 analyzed samples 25 out of them had the virus isolated. Most patients (30%) were female and the median age was 62.5 years. Between the onset of symptoms and mortality, there were an average of 18.5 days in 27 individuals (61.4%) with three or more comorbidities. The scientists claim that over the first two weeks after the onset of symptoms, viral replication was seen in several non-respiratory sites.

According to the findings, SARS-CoV-2 primarily infected and damaged lung and airway tissue. Additionally, the researchers found 84 different body fluids and sites to have viral RNA in one instance 230 days after the patient’s initial symptoms started to manifest. The researchers discovered SARS-CoV-2 RNA and protein in one patient’s hypothalamus and cerebellum, spinal cord and basal ganglia of two additional patients. However, despite a high viral burden, they found minor damage to brain tissue.

Before January 1, India had announced that all tourists from China, Hong Kong, Japan, South Korea, Singapore and Thailand would have to submit to a PCR test. The omicron subvariant XBB.1.5 is responsible for up to 40.5% of new infections in the United States.
