Sumary of Study finds COVID-19 attack on brain, not lungs, triggers severe disease in mice:
- Kumars group found that virus stages in the lungs of infected mice peaked three days after infection, then began to decline.
- Our cognition that it more of a respiratory disease is not necessarily true, Kumar said.
- Kumar said that early in the pandemic, studies involving mice focused on the animals lungs and did not assess whether the virus had invaded the brain.
- Assistant professor Mukesh Kumar, the study lead researcher, said the findings have implications for understanding the wide range in symptoms and severity of illness among humans who are infected by SARS-CoV-2, the virus that causes COVID-19.
