Study: Covid-19 spreads more through the air, excessive focus on cleaning

In one year pandemic, many s evidence is clear. Coronavirus SARS-COV-2 , is mainly transmitted through the air . N ga people who speak and breathe , and spread large and small sprays called aerosols.

According to the latest study published in the journal "The Lancet " , p rekja the virus from surfaces - although reliable - appears to be rare . But despite t s data m s t s past , some public health agencies emphasize the en d of the surfaces pose a threat , so they must be disinfected as m s often.

The result is a confusing public message , n h a h time h when needed clear guidelines , how that s efforts and measures should h ken s advantage parandal tion of spreading s s s virus.

Covida-19 rarely spreads p h r between the surface s . Then why is the clean up so much s premises ?

In its most recent public guidance, the p s Day after day s Suar October of the year s past, the World Health Organization advised: "Avoid touching surfaces, especially in public places, because someone affected with C Ovid -19 , can had touched them before. Regularly clean surfaces with disinfectant standard " .

A representative of WHO said "Nature" in January , it has limited evidence of coronavirus transmission through contaminated surfaces known as ' fomites ' . But they added that they are still considered a possible mode of transmission, citing evidence that SARS - CoV-2 RNA has been identified " in the vicinity of people infected with SARS-CoV-2 " .

And A score s the Centers for Disease Control and Prevention US (CDC) , said on its website the official n s Internet , the transmission p s rmes surface " is not intended to be a common way of spreading jes s h C Ovid -19 " , add j n s also " frequent disinfection of surfaces and objects affected by many people , h iss still a significant is h m ".

This lack of clarity about the risks of ' fomites ' - compared to the much greater risk posed by airborne transmission - has serious consequences. Because in humankind and organizations , they are continuing to ' give priority costly efforts to disinfection when they can deploy more resources to the device with masks , or by improving the ventilation of premises .

Vetëm Autoriteti Tranzit Metropolitane i qytetit të Nju Jorkut në SHBA, vlerëson se kostot e tij vjetore të dezinfektimeve të lidhura me Covid-in, do të jenë afro 380 milion dollarë nga tani deri në vitin 2023. Në fundin e vitit të kaluar, autoriteti kërkoi nga qeveria federale e SHBA këshilla, nëse duhet të përqendrohet vetëm tek aerosolet.

Iu tha që të përqendrohej edhe tek fomites, dhe deri më tani ka drejtuar më shumë burime drejt pastrimit të sipërfaqeve, sesa në trajtimin e aerosoleve. Tani që është rënë dakord sevirusi transmetohet kryesisht përmes ajrit, përpjekjet për të parandaluar përhapjen e virusit duhet të përqendrohen në përmirësimin e ventilimit ose instalimin e pastruesve të ajrit, të testuara në mënyrë rigoroze. Njëkohësisht, agjenci të tilla si OBSH dhe CDC,must p s Day after day s tric s their guidelines on the basis of current knowledge. Nature
