HYDERABAD: Masks have become indispensible with the spread of
coronavirus, but most people are not wearing them effectively, say experts. The repeated use of cloth masks without being washed properly, and touching and adjusting of
face masks often can be dangerous, say
health workers.
According to Dr Vishvanath, a pulmonologist, touching the insides of a mask with unclean hands and repeated use of disposable masks can be dangerous. "Pushing the mask down below the nose and mouth while speaking is dangerous as the outer surface of the mask traps the virus and if used repeatedly without washing, can be infective," he said
Dr Kiran Madala, who did his pandemic certification with
World Health Organization has a piece of advice for office goers and people who work long hours. "The nose and mouth should be considered private parts and need to be covered properly. One should always carry a clean and dry mask before stepping out of the house," he said. A spare mask can be carried and used when the first mask turns dirty.
Masks become so after five hours of use. Dr Sridhar, a consultant doctor with
Apollo Hospital says masks must be removed without being touched in the front.
"It should be removed by only touching the ear loops or the fastening straps. It is important to thoroughly wash hands with soap and water after removing the mask," he said. However, it is not advisable for children below two years to wear masks, doctors say. Their face can be covered with cloth in emergency situations.
Dr Subodh Kanthamuthan, who works with Administrative Staff College of India (ASCI) said "There is no study on effect of dirty masks. Such studies are required."
