Did you know that a violent sneeze can spray clouds of fluids containing hundreds of viruses from a person’s nose and mouth? And did you also know that those clouds can travel up to eight meters (26.2 feet)?
However, there are ways to help avoid infection from coughs and sneezes.
A study by MIT researchers has shown that coughs and sneezes have gas clouds that keep their potentially infectious droplets aloft over much greater distances than previously known. Droplets 10 micrometers in diameter actually travel 200 times farther! And those virus-filled droplets can stay in the air for hours.
Every year, millions of work and school days are lost because of colds and flu. In the United States, The Centers for Diseases Control and Prevention (CDC) estimates the annual direct costs (hospitalization, doctors' office visits, medications, etc) of influenza at $4.6 billion (USD) and causes the loss of almost 111 million workdays. In Europe, one estimate has put the health cost of influenza across the EU at between €6 billion to €14 billion annually, depending on the severity of the season. The World Health Organization (WHO) says annual flu epidemics are thought to result in about three and five million cases of severe illness every year around the world.
More often than not, humans are the main source of infectious diseases. With the cold and flu season in full swing in the Northern Hemisphere, we need to use all the aids available to help battle becoming infected, from boosting immune systems to cleaning the air of germs.
Tips to avoid colds and the flu
- Wash your hands frequently
- Disinfect keyboards, phones, and surfaces regularly
- Get sufficient sleep, as it can boost the immune system
- Avoid stress as it can lower immunity defenses
- Keep rooms at home and work well ventilated
- Use an indoor air purifier with a Hepa filter
Blueair purifiers are designed to remove virus and bacteria in addition to dust, pollen, mold spores, pet dander and smoke. When the Blueair Classic family was tested by accredited CAS Test Technical Services, it removed H1N1 influenza A/PR8/34 with a clearance rate of over 99.99%, as well as Staphylococcus aureus, Escherichia coli and Aspergillus niger (the sterilization rate in 60 minutes was also more than 99%).
