Instead @MASchoolsK12 have stopped testing and decided to let kids with #COVID return to class after 5 days only, while they are likely still contagious according to @CDCgov's own data.

I promised I would provide a way to calculate room air exchange, using a simple MERV-13 filter & a box fan. The sweet spot seems to be 6 exchanges per hour. This means all the air in the room is moved through the filter 6 times in 1 hour. 1/6 #ProtectHCWs #ProtectKids #Covid #BA2
First we need to get the volume of a room. It doesn’t need to be perfect! But note units are important. We are using feet/inches here. Use this calculator & input the measurements, A, B, & C as shown in the graphic below. Order is NOT important 2/6 #Filter…
I found a company that did calculations using a box fan on high speed & MERV-13 filters of different depths. The thicker the filter the BETTER the air flow! Strange but true. Note I added the Air Volume based on a 20” square box fan. 3/6 #N95 #BoxFanFilter…

I have been asked a number of great questions! So let’s go through each point of my “Care & Feeding of an #N95 #Mask”. Bending or crumbling breaks apart the polypropylene fiber bonds, the magic fiber that filters out & traps the virus using electrostatic charge. @DrEricDing 1/12 Image
Electrostatic charge is like a magnet for the virus. #N95 masks do not rely on layers to filter. 90% of their viral filtering ability is due to this electrostatic charge! If you damage this charge the masks become about as effective as a cloth mask. 2/12…
Washing these masks is destroying them. The agitation breaks apart the polypropylene bonds, opening up the filter, it also permanently destroys the ability for the polypropylene to maintain the electrostatic charge. If they are soiled, please dispose. 3/12

बहुत बड़े संकल्प को लेकर चलना है. अगले वर्ष स्वतन्त्रता के 75 वर्ष में प्रवेश करेंगे: @PMOIndia at #RedFort. Unfurls the tricolour for the 7th year running, setting a new record for a non Congress Prime Minister. PM pays respects to our brave martyrs and to our #CoronaWarriors.
India became a challenge for expansionist forces & an inspiration for the world in the war for independence. India came together for freedom. In these times too India has taken a pledge for #AtmaNirbharBharat. Mantra for 130 crore Indians: @PMOIndia at #RedFort. Self Reliance.
India & Indians have the capabilities for #AtmaNirbharBharat.
We need to become capable & full of self confidence. World inter connected & interdependent. India's contribution must increase and for that we must become strong: @PMOIndia at #RedFort #ValueAddition to own resources

Summary of #coronavirus #COVID19 webinar by @JohnsHopkinsIH yesterday:
🔹 No country is fully prepared for an epidemic
🔹 during Ebola outbreak, 10% of tweets had bad info
🔹 Others were rumors about govt conspiracies
🔹 Others were chaos inducing tweets
🔹Propaganda blames various different populations, give rise to discrimination
🔹 There is NO CURE for #COVIDー19
🔹 There is no foolproof preventative
🔹 Surgical masks are NOT EFFECTIVE
🔹N95 #Masks are needed by medical staff. We need them to stay healthy. DON'T stockpile
🔹Community transmission - identify (testing), isolate (hospital), inform (community, health authorities)
🔹Long term care facilities have older, less heathy populations. DON'T visit them if sick. When visiting, use good #hand hygiene
🔹Facility workers should use masks
