With the ongoing 2019 novel coronavirus (Covid-2019) outbreak, frontline healthcare workers in Singapore probably have the toughest jobs right now.

Like this man, for example:

Healthcare workers are ostracised

It doesn't help that some of them are getting shunned by society too.

There have been a number of anecdotal tales of how nurses and paramedics in Singapore have been discriminated against by some people.

Singaporeans write letters of encouragement

But fortunately, the Covid-2019 outbreak has also brought out instances of volunteerism and kindness from others.

Some Singaporeans have written heartfelt letters to the workers.

Organisations such as POWER 98 Love Songs and StandUpFor.SG are particularly dedicated to sharing words of encouragement with the front line personnel.

Members of the public have since submitted their letters on social medias through the hashtags #SGUnited and #braveheartsg.

StandUpFor.SG, which started its movement on Facebook, will print out the letters and distribute them to the healthcare workers from Valentine's Day (Feb. 14) onwards.
