“Long lockdowns to slow a disease can also have catastrophic economic impacts that may themselves affect public health. “It’s a three-way tussle,” Leung says, “between protecting health, protecting the economy, and protecting people’s well-being and emotional health.”
The economic fallout isn’t something epidemic models address, Longini says—but that may have to change. “We should probably hook up with some economic modelers and try to factor that in,” he says.” “}}

May 3, 2020Five of six face masks fail absorbency test, Singapore News & Top Stories – The Straits Times
May 2, 2020interesting suggestions on mask quality:
QT:{{”
For a surgical mask to work, the outer-most layer should be
water-resistant, and the middle layer, which is used to trap bacteria, should not be too porous.
The innermost layer has to be able to absorb moisture such as saliva, mucus and sneeze droplets.
…
An absorbency test found that five of the six masks could not absorb any moisture. That means if the user sneezes, the mask will not be able to contain the droplets, which will remain smeared on the wearer’s face. Absorbency is also an important factor for comfort, allowing the user to wear it for longer hours.

the white internal layer should not burn

the internal layer should be leakproof

Can the coronavirus really live for 3 days on plastic? Yes, but it’s complicated.
May 2, 2020QT:{{”
When the scientists placed virus-laden droplets on plastic, they found that half of the virus was gone after about seven hours. Half of what remained was gone after another seven hours, and so on. By the end of Day Two, there was less than 1/100 of the original amount, and after three days the remnants were barely detectable.
…
For stainless steel, the half-life for the virus was five or six hours, and for cardboard it was even shorter: less than four hours. “}}

Exit strategy
For now, the most likely scenario is one of easing social distancing measures when it’s possible, then clamping down again when infections climb back up, a “suppress and lift” strategy that both Singapore and Hong Kong are pursuing. Whether that approach can strike the right balance between keeping the virus at bay and easing discontent and economic damage remains to be seen.
…
Jeremy Farrar, head of the Wellcome Trust, says a path out of the dilemma now facing the world will come from research. It might take the form of an effective treatment for severely ill patients, or a drug that can prevent infections in health care workers,
or—ultimately—a vaccine. “Science is the exit strategy,” Farrar says. “}}
