"Among the findings of their research paper, which the team plans to submit to a major journal: If 80% of a closed population were to don a mask, COVID-19 infection rates would statistically drop to approximately one twelfth the number of infections—compared to a live-virus population in which no one wore masks.

The mask debate, of course, has been raging for weeks in the States and globally. Pro-maskers assert that the widespread use of face coverings can diminish the spread of COVID-19. Some anti-maskers, including various politicians and public health officials, have insisted that there is no proof of the efficacy of face guards. According to some activists, a blanket mask mandate places a limit on individual liberty and even one’s right to free speech."

"SINGAPORE - A four-legged robot will be patrolling Bishan-Ang Mo Kio Park to remind people of safe distancing measures starting from Friday (May 8). Called Spot, the robot will assist with safe distancing efforts at parks, gardens and nature reserves managed by National Parks Board (NParks) and at parks managed by town councils.

The pilot trial is jointly conducted by NParks, and the Smart Nation and Digital Government Group (SNDGG). The Spot robot will broadcast a recorded message reminding park visitors to observe safe distancing measures. It is fitted with cameras, enabled by GovTech-developed video analytics, to help it estimate the number of visitors in the parks. The cameras, however, will not be able to track or recognise specific individuals, neither will it collect any personal data."
