PREVENTION OF COVID-19; ROLE OF HANDWASHING AND THE FACE MASK

INTRODUCTION

The novel coronavirus (2019-nCoV, Wuhan coronavirus), a virus that originated from the Wuhan province of China is now responsible for 400,000 confirmed cases globally. There are also confirmed cases of the virus in over 199 countries outside China, according to the World Health Organization. This virulent outbreak puts global travelers at the risk of exposure hence the current trend of mask-wearing around china and indeed globally in aim to protect self against the deadly virus. Passing through any international terminal, it’s impossible to ignore a sizable uptick blue (disposable or surgical) face mask in self-imposed muzzling on people’s faces. Another daily lifestyle we have all come to adopt is the judicious use of hand sanitizers and hand wash for hand hygiene. This trend is not only seen on wary passengers and airport staff but has since the recent outbreak become part of our daily lives.

This brings the question, can wearing a medical (surgical) face mask protect you against the new coronavirus? And do performing hand hygiene (Hand wash and Hand rub) offer me any form of protection. I mean the virus spreads through respiratory droplets, what do my hands have to do with this??

DO DISPOSABLE SURGICAL MASK PROTECT YOU AGAINST THE NOVEL CORONA VIRUS?

Can the surgical face mask protect me from the novel coronavirus?

The Centers for Disease Control and Prevention (CDC) ‘’ does not currently recommend the use of face masks among the general public,” reads the most up-to-date FAQ on the federal agency’s website. 

Dr. William Schaffner, an infectious-disease specialist at Vanderbilt University in Tennessee, emphatically states that ‘’the surgical mask plays no role in protecting you against the novel coronavirus’’. The regular kind of mask you’d find online is not all that helpful against any kind of virus,” also warns Amy Shah, a double board-certified medical doctor in allergy and immunology. “Is it bad? No. It’s not like it’s harmful. But will it completely protect you? NO!

WHAT TYPE OF FACE MASK PROTECTS YOU?

A more specialized mask, known as an N95 respirator, can protect you against the new coronavirus, also called 2019-nCoV. The respirator is thicker than a surgical mask and they have tighter-fitting and can filter smaller airborne particles such as viruses.

This mask is however not recommended it for public use because of technicalities surrounding its appropriate wearing and doffing. It is mostly used by health workers.

WHAT THEN CAN I DO?

  • The best thing you can do is wash your hands frequently — with water and antibacterial soap for at least 20 seconds — and to keep your immune system up by assisting your self-defence with lots of vitamin C in the form of food.
  • Wearing Disposable gloves is also a more effective form of prevention when travelling than the stereotypical surgical mask. 
  • Postpone any travel to China. 
  • Avoid touching your eyes, nose, and mouth with unwashed hands
  • Avoid close contact with people who are sick and disinfect frequently touched objects and surfaces. 

Can surgical masks be of some use?

Yes, but the effect is likely to be modest.

Are you still thinking about wearing a surgical mask? Below is the appropriate way to do it:

  • Disposable face masks should be used once and then thrown in the trash. 
  • You should also remove and replace masks when they become moist.
  • Always follow product instructions on the use and storage of the mask, and procedures for how to put on and remove a mask.  
  • If instructions for putting on and removing the mask are not available, then follow the steps below.
  • Putting on a face mask
  • Clean your hands with soap and water or hand sanitizer before touching the mask.
  • Remove a mask from the box and make sure there are no obvious tears or holes in either side of the mask.
  • Determine which side of the mask is the top. The side of the mask that has a stiff bendable edge is the top and is meant to mould to the shape of your nose.
  • Determine which side of the mask is the front. The coloured side of the mask is usually the front and should face away from you, while the white side touches your face.
