Face Masks can Boost Immunity and Slow COVID-19 Infection

Face masks can have a vaccine-like effect by slowing the spread of COVID-19 infection and by generating immunity, according to a new study from California University.

Scientists are comparing face masks to variolation. Variolation was followed before a smallpox vaccine was discovered.

Tips for Safe Hotel Stay This Labor Day During the COVID-19 Pandemic
Travelers choosing to stay in hotels during the Labor Day weekend should keep a few essential safety tips in mind, especially amid a pandemic. From choosing the right hotel to carrying one's gear of sanitizers and face masks, tourists should take each step with caution to curb the virus's spread.

‘Wearing face masks can filter out some of the virus-containing droplets. Masks can become a form of variolation by generating immunity and slowing the spread of COVID-19.’

Variolation is a process in which people who did not have the disease were exposed to material from smallpox patients that would call mild infection. The mild infection would protect the people from contracting the full disease.

The scientist considered the possibility consistent as the theory of viral pathogenesis states that the severity of the disease is proportional to the amount of virus infecting.

Face masks filter out virus-containing droplets. Thus, wearing a mask might reduce the amount of the virus a person inhales.

COVID-19 Death Toll Reaches Almost 200 Among Doctors in India
Healthcare workers around the world are at an increased risk of developing COVID-19. In India, the number of doctors who have died of COVID-19 rises to 196.

An experiment performed on hamsters supported the theory of the researchers that wearing a mask has similar effects to variolation.

Animals with stimulated masking were less likely to be an infection or had milder symptoms when compared to unmasked hamsters.

Efficiency of Different Masks in Protecting People Against COVID-19
Efficiency of 14 different face masks and covering in preventing the spread of viral droplets, were evaluated by a group of researchers. They used a simple, cost-effective method.

Wearing a mask could reduce the rate of new infections. By reducing the rate of new viral infections, the proportion of asymptomatic people would also be reduced.

The researchers referred an outbreak in a closed Argentinian cruise ship. The passengers were provided with surgical masks, and the staff were given N95 masks.

New Method Allow Surgical Masks To Kill Viruses
Surgical masks are designed to kill influenza viruses that cause infections, reveals study.

The rate of asymptomatic infection was 81% on testing when compared with 20% in earlier cruise ship outbreaks without universal masking.

It is crucial to wear a mask as it can generate immunity and reduce the spread of the virus.
