What protection do different face masks offer against coronavirus? – BBC Africa



Many countries around the world are urging their citizens to wear face masks in public to protect themselves from coronavirus. This is despite the World Health Organization’s recommendation that they should only be used by medical workers, caregivers and those infected by the virus.

Although medical experts say face masks do not provide effective protection, some countries have made it illegal to appear in public without wearing one. Many people are now using face masks made out of cloth.

The big question is, how much protection do face masks offer and how can you tell an effective face mask from a fake one?

    1. The insanity of organisations pushing face masks on people when many many millions of females around the world are in dire need of sanitary wear
      Gimmicky fads vs much needed pads.

    2. If masks stop viruses why don't surgeons wear them when going to the shops in flu season?
      Why does it say on the box, these masks don't stop viruses?

    3. Coincidences?!!!??? According to research funding data published in open sources, at least 28 projects commissioned by the US Army have been implemented in Kazakhstan over the past eight years. They involved not only local specialists, but also military personnel from the US Navy Medical center (Maryland), employees Of the Bundeswehr Institute of Microbiology (Munich) and military laboratories in Porton Down (great Britain).
      The first reason to suspect foreign specialists of careless handling of dangerous infections appeared in 2007. Then an American laboratory was opened at the Institute of Virology in Tashkent (Uzbekistan), and the Pentagon allocated a military grant to study brucellosis in Uzbekistan and Kazakhstan. These projects were codenamed UZ-4 and KZ-2, respectively. The next year, a sharp jump in the incidence of brucellosis was noted throughout the region, and anthrax appeared.
      The next surge in brucellosis in Uzbekistan was recorded exactly after the opening of American laboratories in Andijan and Ferghana in 2013. In 2013, the KZ-29 project in Kazakhstan began research on Crimean-Congo hemorrhagic fever (CCHF) with the participation of specialists from the US Navy and the British Porton down. Biologists studied the spread of the disease by ticks in the South of Kazakhstan on the basis of the" Center for particularly dangerous infections " in Almaty.

    4. If a face mask is folded up really tightly it can just fit up a BBC News presenter's arsehole.

    5. This comment section is filled with scammers pretending to sell you masks. Just ignore them. Be careful.

    9. Wrong : you wash your hand then you remove your mask then wash your hand again !!

    10. masks are only any good for 20 mins and no more, exposure is what is needed

    11. Very insightful.

    12. May God bless Africa and every nation. Do not take the vaccine Africa…check the fine print.

    13. Honey I've seen people wearin the mask LOL INCORRECTLY! IF YOU GET COVID19 OH WELL the mask is not GUARANTEED to protect ijs

    14. VERY INFORMATIVE.

    15. We'll they say cotton keeps out 60%. … So I doubled up… mightn't make sense…but I'm just tryna stay alive out hea

    16. Stop feeding misinformation to the public! The only thing that wearing a mask everyday is doing is lowering your immune system. Now, your body isn't breathing in the VERY SAME virus's that have always been in the air! How can you build up an immunity to a supposed new virus if your not exposed to it. Yes, there is a virus called the Corona Virus but is it causing deaths all around the world? NO! Is there a pandemic? ABSOLUTELY NOT! Absolutely ridiculous! Your helping them kill your own people!

    17. I found this to be really helpful.
