INDIA: The actual method of coronavirus (SARS-CoV-2) transmission has remained a mystery. Previously considered to spread by contact with surfaces, epidemiologists have shown that countries whose citizens donned masks throughout the epidemic were less afflicted.
However, there was no quantifiable evidence that the infection was spread through coronavirus particles (virions) in the air. The capability of COVID-19 transmission across the radio has already been proven.
The airborne transmission of SARS-CoV-2 was confirmed in a study conducted by scientists from CSIR-CCMB, Hyderabad, and CSIR-IMTech, Chandigarh, in collaboration with hospitals in Hyderabad and Mohali. The research results have been published in the Journal of Aerosol Science.
The researchers examined the coronavirus genome content in air samples collected from COVID-19 patients’ homes. These samples were taken from hospitals, confined rooms where only COVID-19 patients spent a brief time, and the homes of COVID-19 patients who had been quarantined at home.
They discovered that the virus was frequently detected in the air around COVID-19 patients and that the incidence of positive cases rose as the number of patients on the premises grew.
The virus was found in both ICU and non-ICU portions of hospitals, implying that patients released the virus into the air regardless of the severity of the infection.
The researchers discovered live coronavirus in the air, infecting living cells and traveling across large distances. To prevent the spread of the sickness, scientists recommend that people continue to wear masks.
“In the absence of ventilation, coronavirus can stay in the air for a long time in closed spaces. When two or more COVID-19 patients were present in a room, the probability of obtaining the virus in the air was 75 percent, compared to 15.8 percent when one or no COVID-19 patient was present,” Shivranjani Moharir, a scientist engaged in the study named “Upied the room” said.
“Our findings are consistent with earlier research that suggests the concentration of SARS-CoV-2 RNA in indoor air is higher than in outside air. Compared to indoor community settings, the attention is higher in hospitals and healthcare settings that host a more significant number of COVID-19 patients,” Moharir explained.
“As we return to undertaking in-person activities, air surveillance is a useful tool for predicting the possibility of infection in settings such as schools and meeting rooms. This can aid in developing infection control methods,” Dr. Rakesh Mishra, the study’s principal scientist and Director of the Tata Institute for Genetics and Society, is an AcSIR Distinguished Emeritus Professor at CCMB and an AcSIR Distinguished Emeritus Professor at CCMB.
He argues that, in addition to coronavirus, the air monitoring technique might be used to track other airborne infections.
