The air transmission rate of the new crown or the contact surface is 1000 times: the most dangerous computer keyboard in the gym is very safe

According to the Science and Technology Daily, the latest research in the United States shows that the transmission rate of the new crown virus in the air is higher than that of the contact surface.1000Times, the extracted samples show that the gym is the most dangerous, the computer keyboard is quite safe, and the probability of positive detection is much lower.

Writing in the recently published “Journal of Exposure Science and Environmental Epidemiology”, scientists in the United States pointed out that after testing samples collected from the air and surfaces around campuses, they found that the probability of people contracting the new coronavirus from the air they breathe is Infected from contact surfaces1000times.

The team collected a total of250multiple air samples, where1.6%of samples tested positive for COVID-19.while in500Among multiple surface samples,1.4%positive.

The results showed that the most dangerous environment was the gym, where in the samples collected at the gym,75%air samples and50%of surface samples came back positive, with water dispenser buttons being the most vulnerable to contamination, while none of the samples taken from fitness equipment came back positive.

Also, samples taken from an office or computer keyboard, light switch, table top, microwave oven, refrigerator handle, or student desk are much less likely to be positive.

The researchers compared the positive samples to actual COVID-19 cases on campus and found that,The probability of infecting airborne particles of the new coronavirus is approx.1/100; and the probability of contracting the new coronavirus by touching a contaminated surface is1/100000the former is the latter1000times.
