Delta variant causes more severe infection, say reports

Coronavirus update: The Delta variant of Covid-19 may cause more severe illness than all other known versions of the virus and spread as easily as chickenpox, reports quoting an internal document from the US health authority has said.

The document from the Centers for Disease Control and Prevention (CDC) outlines unpublished data that shows fully vaccinated people against Covid-19 might spread the Delta variant, first identified in India, at the same rate as unvaccinated people, the recent update on coronavirus reveals.

Dr Rochelle P Walensky, director of the CDC, has acknowledged that vaccinated people with so-called breakthrough infections of the Delta variant carry just as much Covid-19 virus in the nose and throat as unvaccinated people against coronavirus and may spread it just as readily, if less often. But the internal document lays out a broader and even grimmer view of the Delta variant of Covid-19.

The Delta variant of coronavirus is more transmissible than the viruses that cause MERS, SARS, Ebola, the common cold, the seasonal flu and smallpox, and it is as contagious as chickenpox.
