Can coronavirus be transmitted through an air conditioner?


As summer nears and the threat of
Covid-19 still persists, the next
worry is whether coronavirus can be transmitted from air conditioners (A/C) — a necessity of summers.
Health experts have, however, suggested that the chances of contracting coronavirus A/C ducts are close to zero.
According to a report published by Gulf News, health expert Dr Adil Sajwani say that the chances of transmitting the virus through the A/C is low and close to zero as studies have shown Covid-19 was not airborne.
“So far, we have not seen any evidence that Covid-19 can be spread through air conditioning systems,” he said. “The virus is mainly transmitted through contact with respiratory droplets rather than through the air. If there is a possibility that the virus can transmit through an air-shaft then all of us would be infected by now.”
He added that if an infected person is staying in the same building it does not mean they can infect other residents through the air. “It can only happen through close contact scenarios,” he said.
Referring to a study that had been conducted in China earlier this year on a cluster of coronavirus cases that had all originated from the same restaurant, Sajwani said, “It wasn’t through the air conditioning system.”
Another expert, Dr Ahmad Al Addin from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), has also there was no evidence of virus transmitting through the air ducts.
Dr Added added, “There is no physical proof it happened or can happen. As a precautionary measure, people should clean the filters and use multimedia filters (which utilises three or more layers of gravel rather than just sand in the filter) as well as keeping the temperature between 20 to 25°C.”
A new study confirms the legend that dogs rescue people they care about. Many of us enjoy the special bond that occurs between humans and dogs. We are two different species with different instincts and goals, and yet, the connections that we make with our canines can be deep.
Dogs’ loyalty to their owners is legendary, and there are countless tales of dogs rushing to the aid of endangered people. Are these stories real or simply apocrypha? Researchers at Arizona State University (ASU) in Tempe, Arizona, decided to find out.
In the first of the two control experiments, dogs watched a researcher drop food into an empty box. Just 19 of the 60 dogs were able to open the box and get the food.
