Hair loss is new post COVID-19 complication: Doctors

 The sudden onset of hair loss -- Telogen effluvium -- is caused majorly due to stress, nutritional deficiency and inflammatory reactions caused by the infectious disease, the health experts explained. Normally a person can lose up to 100 hair per day, but due to Telogen Effluvium it can increase up to 300-400 hair per day.

How COVID variants turns more infectious, antibody resistant

The team developed structural models to identify changes in the virus's spike protein. Cryo-electron microscopy allowed atomic level visualisation, while binding assays enabled the team to create mimics of the live virus that directly correlated with its function in host cells. From there, the team used computational analysis to build models that showed the structural mechanisms at work.
