To check for SARS-CoV-2 transmission, the team of scientists asked for signs and symptoms of COVID-19 and performed blood tests to identify people who contracted the infection.
Their Conclusion? Masks Work.
At the end of the study, the researchers concluded that masks work.
Results showed that the number of confirmed, symptomatic cases in the intervention group was 10% lower than in the control group.
Now, 10% seems like an insignificant figure, but the researchers considered that their intervention increased masking from 14% to 43%. Imagine what 100% masking would have done to prevent COVID-19 transmission.
Another thing the study discovered is that villages from the intervention group had a 34% decrease in SARS-CoV-2 cases among senior citizens – a population considered to be at risk for severe infections.
Finally, the team of scientists established that surgical masks are genuinely better than cloth masks. This is in line with the conclusions from other studies.
