A subject coughing in a cyclic incident. A qualitative examination of airborne droplet transmission with and without wearing a surgical mask. The top and bottom figures show the results at 2 s and 3 s, respectively. Wearing a surgical mask that exhibits an initial efficiency of ～91%. This cannot prevent the transport of the saliva droplets away from the subject. Many droplets penetrate the mask shield and some saliva droplet disease-carrier particles can travel more than 1.2 m. For visualization, the droplets were scaled by a factor of 600 compared to their actual size. The environmental conditions are zero wind speed, ambient temperature 20 °C, pressure 1 atm, and relative humidity 50%. The mouth temperature is 34 °C and the face skin temperature is 32 °C. 775

A recent study published Wednesday in the New England Journal of Medicine suggests that antibodies might protect people who've already had COVID-19 from being reinfected for at least six months.Researchers looked at 12,541 healthcare workers at Oxford University Hospitals in the United Kingdom and were followed for up to 31 weeks.In the study, researchers investigated the incidences of COVID-19 infection by conducting polymerase chain reaction (PCR) tests on the healthcare workers who had tested positive and negative, including both symptomatic and asymptomatic cases.The study results showed that 11,364 did not have antibody levels, and 1,265 had positive results, which also included 88 healthcare workers in whom seroconversion occurred during follow-up. A total of 223 anti-spike–negative health care workers had a positive PCR test (1.09 per 10,000 days at risk), up to 100 during screening were found to be asymptomatic, and 123 were to have symptoms, the study found.Researchers said that individuals who had anti-spike antibodies had no symptomatic infections. 1083
