Does spraying the streets with disinfectant kill the covid virus?

Spraying public places to kill virus not recommended - WHO

This post noted several posts about barangay staff spraying the  streets again presumably as  deterrent./defenses vs covid19

This post wonders the logic and relevance in this campaign considering that 1.  It was considered since 2020 to be ineffectual,  2.  WHO is if it considered the gold standard vs covid 19 considered it to be harmful.   One doctor, a member of the military, died at Philippine Arena, after being exposed to a misting facility.  

Again covid19 is a drop infection and the virus being just a molecule can not survive outside a human host with moist membrane for a long period of time.

What the military police frontliners must watch for:   are 1.  crowds.  2.  mass gatherings 3.  especially in enclosed or unventilated spaces.

We also seek the barangay officials, police to treat the people as people not as subjects or enemies to be penalized punished for non compliance.   So far all we see is a display of power and might over the populace,.  

We stop the virus.

And there are options aside from lockdown and vaccines whose safety are suspect

1,  Lianhua 

2.  Ivermectin

But these alternatives are enmeshed  in politics bickerings and  difficulties.    We hope the govt helps rather than suppress punish and overpower.  

Clarity on how covid is transmitted - THROUGH 3 CS -- CROWDS, CLOSE PERSONAL CONTACT, ENCLOSED SPACES

Despite stringent measures, covid19 cases have surged and registered the highest increase this March 2021 of 8000 cases.

What has caused this surge?

      1.  Growing laxity because of the  on going vaccination

      2.  Too early opening of the economy?

      3.  Mix up on understanding of the mechanism of covid19 transmission

      4.  Politicalized and or militarized implementation of countermeasures vs covid 19

This post would like to touch on #3.   Many have been influenced by the movie ""Pandemic" where many are led to believe that the virus is transmitted via fomite.

In many literature available, covid19 is a drop infection and is spread by saliva or sputum coming from a sneezing, talking, coughing or singing individual  in an en closed  space, crowd and close personal contract.   And the virus attaches to mostly moist tissues of the throat and nose.  The virus being only made of molecules and not of living organism can not exist in an open atmosphere especially where there are elevated temperature.

      But what measures do we see:

      1.  Foot bath;

      2.  Disinfection

      3.  Lockdowns

      4.  Check points

      5.  Traffic control

In many parts most of the cases came from close personal contact with infected persons in hospitals (mostly that) or contact with persons in hospitals:  So we must be on guard always with first layer of infection or that of third (reinfection from the secondary contact)

All the above do not address the primary mode of infection.    3, 4, 5 are mere declaration and show of force and might by the government;  the disease transmission is minimally addressed by limiting and slowing the movement of persons.   

What the govt must watch are the family affairs:   parties, gatherings, baptism, funeral where people are carefree do not wear masks, talk freely, for hours, -  situations that are ripe for the covid19 transmission.

NO NEED TO WONDER

Many foolish statements on presser and newsfeed re Covid 19

It is more fun criticizing

One of the important lessons this post learned in Post Graduate course and in teaching graduate courses is the train everyone in logical and critical thinking.

Thus it pains me that certain statements border on lack of thinking and  outright stupidity.  Even decisions that are being made.

1.  We are winning the war vs Covid 19.  Whoaa it is not going down, It is not zero.   While the deaths are declining the number of infections arent.  What;s wrong with our data analysis and that numbers tell a story.   It sometimes tantamount fooling people if not outright insult to intelligence of many. 

2.  We can resume classes masses, or mall operation, or resto.   But these places events are superspreader.  The change in CQ classification ran against the stats.   Furthermore, the history of Covid19 spread shows that they take place in crowded space, where there close personal contact and closed spaces.  And we tempting the virus by doing all of these.   Contrary to science and  logic

3.  Fighting covid with guns, and armored personnel carrier and strict military rule.    As if the enemy virus are visible soldiers of war, and  germs. 

The disinfectant the street spray would seem to indicate that roads are reservoir of the virus.  Covid is spread via drop infection.    That means being infected by aerosol droplets generated by shouting talking, laughing  aside from coughing and sneezing.   Many advertise the misting solutions as antiviral.  We know this to be untrue.    Hence we unwittingly killled a doctor with disinfectant mist.
