A new study by researchers at UNSW Sydney explains how well cotton or cloth masks work.
Thus, the study says, these masks must be washed daily at high temperatures to be effective against the transmission of the virus.
“Both cloth masks and surgical masks should be considered contaminated after use. Unlike surgical masks, which are thrown away after use, cloth masks are reused. Although it can be tempting to wear the same mask for several days in a row or we wash it quickly, our study suggests that this increases the risk of transmitting the virus, “said Professor Raina MacIntyre, who coordinated the study.
It is important to know that the study is five years old and those who did it did not test the masks for SARS-VOC-2. However, several pathogens such as rhinoviruses and seasonal coronaviruses were included in the study.
“Although it is unlikely that someone in the community, wearing a cloth mask, will come into contact with a healthcare worker who is exposed to a high level of virus, we recommend washing the mask daily. The coronavirus is highly contagious and still it is “A lot of things we don’t know about him. That is why it is important to take all precautions, “said Professor MacIntyre, according to Medical Express.
WHO recommendation
WHO recommends washing masks in a machine at a temperature of at least 60 degrees Celsius. Also use detergent. The washers have a base temperature of 40 degrees when washing, so you have to go to the settings. It is recommended. to work with the washing machine, because we cannot wash our hands at a water temperature of 60 degrees. The clear message is that cloth masks work, but you have to wash them after each use, ”added the specialist.
