Reading some comments here, I noticed some ppl got worried over coronavirus. Well, one should worry of course, but....
I have always been wearing masks consistently especially in airports and especially inside the aeroplane even before the outbreak of this coronavirus.
Actually there's a much more dangerous pathogen out there compared to coronavirus but probably due to lack of media exposure, not many people are aware of it. Furthermore, some thought it has gone extinct but it's not. And that is Tuberculosis (TB).
TB (especially XDR-TB where there is no cure) is way worse compared to coronavirus. The number of cases in both Malaysia and Japan are in the thousands. Thousands as in over 10,000 new cases every year (both in Malaysia and in Japan respectively). You read that right.
TB grows very slowly inside you unlike coronavirus. Probably due to this, no one bats an eyelid.
So, some ppl who have been coughing for months probably don't realise they are suffering from TB until they get really sick and started coughing blood (after several months of coughing "normally").
And due to that, I always wear mask in the aeroplane because there have been several documented cases of transmission of TB inside a flight.
Compared to coronavirus, TB is very "airborne" unlike coronavirus which is mainly transmitted through respiratory droplets. Because the mycobacterium tuberculosis can stay suspended in the air for several hours, which is unlike coronavirus that is transmitted more similarly like influenza.
Understandably TB is more contagious but its curable and not quick to die from compared to coronavirus
