When is stupid PAP going to stop making it mandatory to wear face masks when going out?

i hope no one ever gets caught on the raw end of any stick. sounds really painful
I think she's talking about my broomstick.
The problem is once you get caught to be the minority people with minority needs, you get caught all the way for the rest of your life in Singapore. From minority single below age 35 with hdb housing need to minority single above age 35 with hdb housing need but with private property investment, to minority investor with foreign properties and need to travel overseas but robbed of coronavirus free medical treatment and integrated shield plan coverage.i hope no one ever gets caught on the raw end of any stick. sounds really painful
Frankly it doesn't matter if they require people to scan SafeEntry and wear masks.
By the way, in case you haven't noticed already, recently the daily coronavirus number has started to include imported cases.
Keeping the borders open while having an election and getting people to vote. What could go wrong?

And maybe extra like being minority people with minority medical needs and made to wear face mask on foot path or open space with no or few people around.
Funny why they didn’t open the border with Malaysia but opened border with India Pakistan Philippines etc with imported cases from these countries.Frankly it doesn't matter if they require people to scan SafeEntry and wear masks.

I read somewhere that face mask worked to prevent infection by an infected hairstylist cutting hair on customers wearing masks too. Masks work for crowded places but what is stupid is to make it mandatory at foot path or open space with few or no people around.
in sg the density of people is high. thus anytime someone can be around your corner or behind you in seconds. there won’t be enough time to put on your mask in 6.9 seconds or less. by the time you put it on someone would already have farted behind or in front of you. moreover, a loud wolf whistle would project aerosolized saliva 6.9 feet into your beautiful face. firecrackers too. they can suddenly discharge out of nowhere.
Studies have already shown that the virus is airborne. This means it is spread via circulating air and can float around for hours.
Cloth masks offer no protection either way plus the virus can enter the body via the eyes.

Coronavirus spreads through the air, 230 scientists write in open letter to WHO
7-8 minutes
The World Health Organization (WHO) has downplayed airborne transmission of COVID-19 since the pandemic began but now more than 200 scientists are making a plea for action, warning people they aren't as protected as they may think.
The WHO's view has so far been that COVID-19 is spread predominantly through large respiratory droplets — the ones that come flying out of our mouths when we cough, sneeze and speak but then quickly fall to the ground.
The risk of airborne transmission has not been recognised by the WHO, except in some health care settings.
But now 239 scientists from 32 different countries and many different areas of science (including virology, aerosol physics and epidemiology) have penned an open letter urging the WHO to change their advice.
"We ignore COVID-19 airborne spread indoors at our peril," the scientists say.
If their plea is heard, the ways in which the world attempts to control the virus could change dramatically.
What's airborne transmission?
The letter, led by internationally recognised air quality and health expert Lidia Morawska from the Queensland University of Technology, makes an appeal for public health organisations like the WHO to address the "overwhelming" research on the dangers of microdroplets.
These are the very tiny respiratory particles (of 5 microns or less in diameter) that you emit when you breathe, speak, laugh, sing and so on.
Because these particles are tiny and light, they can remain suspended in the air and then inhaled by someone else, a bit like cigarette smoke.
This is in contrast to larger, heavier respiratory droplets, which fall quickly to the ground.

Professor Morawska says scientists have demonstrated "beyond any reasonable doubt" that those microdroplets pose a risk beyond 1 to 2 metres, potentially making the 1.5 metre social distancing rule inadequate.
While scientists don't know exactly how long microdroplets can linger in the air, it could be hours.
"We are concerned that people may think they are fully protected by following the current recommendations, but in fact, additional airborne precautions are needed to further reduce the spread of the virus," Professor Morawska says.

Professor Lidia Morawska says viruses can potentially last in the air for hours.What does the research say?
The scientists say that airborne transmission appears to be the only "plausible explanation" for several superspreading events.
Of particular importance was a study (yet to be peer reviewed) of a restaurant in Guangzhou, China, where 10 people from three different families became infected but none of the waiters or 68 other customers did.
Professor Morawska, who was not involved in the study, says the authors observed no evidence of direct or indirect contact between people, but showed how the transmission occurred through the air in a crowded and poorly ventilated space.
In that restaurant, there was no outdoor air supply apart from the brief and infrequent opening of a fire door.
The researchers found a "recirculation envelope" formed over the three families' tables, which were in the direct line of one air conditioning unit. All other tables were being serviced by four other air conditioning units.

The study concluded that aerosol transmission had some role in this outbreak, as some customers who became infected were sitting as far as 4.6 metres apart and we know that even a cough only pushes large droplets around 2 metres away.
Many studies conducted on the spread of MERS and influenza have also proved the risk of aerosol transmission, Professor Morawska said.
For example, 72 per cent of the 54 passengers on a plane in Alaska which had no ventilation for 4.5 hours contracted influenza in 1977.
"There is every reason to expect that SARS-CoV-2 behaves similarly, and that transmission via airborne microdroplets is an important pathway," the open letter says.
What does the WHO say?
In the latest interim guidance, the WHO said current evidence suggests COVID-19 is primarily spread through large droplet transmission when people are within 1 metre of each other.
It also warns that transmission may occur through fomites (inanimate surfaces or objects) however experts believe that risk is quite low.
Today the Lancet published commentary from a microbiology expert in the US who claimed the risks of surface transmission had been "exaggerated" and based on studies with little resemblance to real life.
The WHO says aerosol transmission may only occur during aerosol-generating procedures in healthcare settings, for example intubation (inserting a tube through a person's mouth and into their airway) or resuscitation.
The WHO says more research is required to determine the risk of airborne transmission in other environments.
"High quality research including randomised trials in multiple settings are required to address many of the acknowledged research gaps," the WHO said in their latest advice on masks.
The debate
Euan Tovey, who specialises in the role of aerosols in disease transmission, is one of the 11 Australian scientists who signed the open letter.
He says the WHO's stance on transmission is based on "old fashioned thinking about the behaviour of particles".
Professor Tovey says this was reflected by their official recommendation of 1 metre social distancing.
"One metre is pretty close, particularly indoors ... and we think a lot of transmission comes from smaller particles concentrated within about 1 metre in a room," he said.
Why does it matter
The scientists acknowledge there are still parts of the puzzle of evidence missing when it comes to airborne transmission but say we still have much to learn about large droplet transmission too.
They say until we have a vaccine, all routes of transmission must be interrupted and if the importance of ventilation isn't recognised, there will be "significant consequences".
"People may think that they are fully protected by adhering to the current recommendations, but in fact, additional airborne interventions are needed for further reduction of infection risk," the scientists say.
They also believe the matter is of "heightened significance now" as countries push ahead with re-opening measures.
'It is Time to Address Airborne Transmission of COVID-19' will be published in Clinical Infectious Diseases journal on Tuesday.

Yesterday I went out is already less hot and humid and yet walking 15 minutes on foot path is hard to breathe and sweat a lot.
Also you invested your jibye in jb so it is very leesonable to rob you off the covid treatment
KNN
KNN did you smell your jibye after the 15mins walk ? KNN
Actually I think Sg density is not that high. There is plenty of safe distancing space on covered walkway and foot path. The hdb roof top garden is so pretty and empty almost all the time.
wah ah chiobu, you spend so much time hiding from wolf whistlers alone at roof top garden huh? no wonder can’t see your pretty face around.
Ya I think the cloth mask is more to protect other people from infection. But better than nothing I guess. Cloth mask is a problem for breathing indeed. The paper mask is much more comfortable to wear.
