Abnormal Immune Activity Found 8 Months Covid 19

Scientists have spent the last few years trying to understand the novel coronavirus, SARS-CoV-2Trusted Source, which is responsible for the Covid 19 pandemic. As new variants of the SARS-CoV-2 virus emerge, scientists continue to study their effects to find ways of keeping the global population safe.

A new study has reported that individuals with long Covid 19 experience dysfunctional immune activity 8 months after the initial illness. Long , also known as post-acute Covid 19 Trusted Source, is a term to describe the effects of that linger for weeks or months beyond the initial illness. The symptoms often involve respiratory and physical distress and, more recently, cardiovascular distress.

Abnormal Immune Activity Found 8 Months Covid 19The study, led by scientists at The Kirby Institute, University of New South Wales, Australia, appears in the journal Nature Immunology Trusted Source. In the study, the team defined long Covid 19 as the occurrence of one of three major symptoms of fatigue, chest pain, or shortness of breath in the fourth month of infection. A total of 31 out of 147 individuals fitted the description.

The scientists then matched the individuals using gender and age, with 31 asymptomatic controls from the same cohort who did not report symptoms in the fourth month but were symptomatic during the acute phase of Covid 19. The researchers also recruited a fresh population of individuals who tested negative for SARS-CoV-2 alongside individuals who had contracted other human coronaviruses but not SARS-CoV-2. This group served as the control.
