Covid 19 may be airborne or spread via aerosols - scientists

It is more fun criticizing


Global experts warn of coronavirus airborne threat


Coronavirus might spread much farther than 6 feet in the air. CDC ...

Doctor's Note: Can coronavirus spread through the air? | Health ...


Microdroplets might explain the rapid spread of COVID-19 | World ...


From Science Alert

For quite a while we believed in both the droplets and fomite theory of spread of the virus and perhaps our efforts to control the virus  were misdirected.

Under the fomite theory we view the virus not much differently from germs and use disenfection tents foot wash, taking showers every time we get out,  wearing globes.

Under microdroplets theory, it is to be emphasized that we get the virus only when there are persons together:   close personal contact, prolonged period and is engaged in talking, singing laughing or singing.    Thus are spread in closed environment like churches, offices, restaurants, and other
enclosed spaces; even trains and buses

Church leaders were emotional about not letting them hold services and masses.  But churches in USA closed their churches after people got sick and died attending church services.

From NY times - resurgence emerging from bars, strip clubs and churches

The mere act of breathing creates aerosols that stay for hours even up to distance of 10 meters (not 2 meters as is commonly thought)

Also many spreaders are asymptomatic  - do not cough have sore throats or febrile

     1. Thus it was it was useless  to screen pedestrians or entrants to a establishment, or check points
          with temperature scanner.  Roughly half of the spreaders are asysmptomatic

    2.  The foot bath and the  showers are useless because the virus dies when exposed  to the sun, nor
          can streets be reservoirs of the virus.

    3.  It is wrong to lockdown people in their homes.  and yet allow them to congregate in closed
        spaces as mall for SAP distribution

   4.  The lifting of liquor ban which spans parties and gatherings should have not happened
         The superspreaders started in parties fueled by liquor..

The govt was in a hurry to lift the ECQ to give way to revival of economy despite the fact that number were rising.    And the first to be opened are places were people gather together or mass together for virus spread.

    1.   At construction site, there were about 700 workers found to be positive.  What is the science
         behind this?   Workers are in an enclosed space and they constantly shout

    2.  A number of train workers tested positive.  Why they come into contact with thousands of
         passenger daily.  And just one carrier....

   3.  Some towns are booming in number of infections... why are they transmitting may be the
        rapid testing give false negative results.  Dapat talaga PCR test.     Natural kung hindi pa incu-
        bated ang virus mag negative.  When they incubate that is the time they spread.    Despite
        the objection of OFW for quarantine after negative for test, dapat talaga may quarantine.
