As we are now in the COVID-19 pandemic, The Centers for Disease Control has recommended that people wear a cloth mask or shield over their face when going out into public & some areas have even made it mandatory. The reason however is not to protect yourself from coronavirus, but to protect others from you spreading the illness with a sneeze or cough.

Coronavirus has been proven to be asymptomatic  meaning that the illness doesn’t show any symptoms in some cases, & that an individual could carry & pass it along without being aware.

Curious as to how fast a cough spreads? Watch this video recently released by released by the University of Helsinki, Aalto University, the Finnish Meteorological Institute & VTT Technical Research Center of Finland demonstrating a simulation. They have concluded that the virus can last in the air for a longer period of time than initially presumed & could be passed even if they are 6 feet apart.

Aalto University Assistant Professor Ville Vuorinen claims, ‘Someone infected by the coronavirus, can cough & walk away, but then leave behind extremely small aerosol particles carrying the coronavirus. These particles could then end up in the respiratory tract of others in the vicinity.’

As recommended by a researcher of the institute, you should “stay at home if you are unwell & that you maintain physical distance with everyone. The instructions also include coughing into your sleeve or a tissue & taking care of good hand hygiene.”

Until further notice, it’s best to practice social distancing, only entering into public places if absolutely necessary & if you do, please consider wearing a mask.
