Can COVID-19 remain in the air, after an infected person has passed?

Good news! The World Health Organization had released a statement that COVID-19 is not transmitted by air. The only way the virus can remain in the air is in “respiratory droplets” – small particles of mucous or saliva emitted by a sneeze or cough. Infection prevention is important for our society.

Why is this good news? 

These “droplets” are heavier than air and therefore do not remain in the air for long periods. While we still need to keep our social distance of over 1m, it does not seem that the coronavirus remains in the air for long periods. Additionally, it is almost certain that the contamination does not travel further distances than 1m through the air. Infection prevention is important for our society.

Best practices remain the same

Wearing a mask when expecting exposure to other people is still a good practice, as is the very simply ritual of hand washing. The respiratory droplets do not remain in the air, but when they land on surfaces, they may still be infectious for a while. Touching these surfaces and then your face puts you in a high risk of infection – so wash your hands often to stay healthy!

You can’t manage what you can’t measure, and it is impossible to enforce compliance without managing it!

According to CDC, Hospital-Acquired Infections (HAI) are among the most common medical events causing death, especially among children.  Proper hand hygiene can prevent up to 1 million deaths annually and reduce HAI by up to 40%. 

WHO states that hand hygiene is a critical and cost-saving intervention in the prevention of infection and the spread of disease. But, only 50% of all medical care workers wash or sanitize their hands correctly.

With Soapy technology, you can now have an overview of staff compliance with hand hygiene protocols — increasing patient safety and care quality.

We passionately believe that good hand hygiene quality is the key to a disease-free life in a world replete with harmful microbes. Soapy brings hand hygiene out of the restroom and takes it into the future!
