Leaving a positive mist of disinfectant of their wake, China’s hazmat-clad well being staff are cleansing properties, roads, parcels and even individuals — however greater than two years into the pandemic, specialists say it’s a futile measure in opposition to Covid-19.
China is tied to a zero-Covid technique, wielding snap lockdowns, mass testing and prolonged quarantines as a part of unrelenting efforts to quash virus outbreaks regardless of the price to the financial system or freedoms of its individuals.
Amongst its arsenal of virus controls is disinfectant spraying, which a prime Shanghai official earlier this month lauded as a key a part of a “grand assault” on the virus.

The sight has turn out to be some of the visible expressions of China’s zero-Covid coverage, which has taken on a political dimension as President Xi Jinping has pegged the legitimacy of his management on defending Chinese language lives from Covid.
Private possessions and residential furnishings lie amid clouds of cleanser, the pictures present — whereas in different instances the targets are metropolis streets, partitions and parks.
However such labour-intensive campaigns are comparatively pointless in opposition to a virus that spreads by droplets expelled in coughs and sneezes into the air, specialists instructed AFP.
“Since an infection by touching contaminated surfaces isn’t an essential route of transmission, intensive and aggressive use of disinfectant isn’t vital,” mentioned Yanzhong Huang, senior fellow on the New York-based Council on Overseas Relations.
Transmission by contaminated surfaces and objects is feasible however comparatively uncommon.
The chances haven’t deterred China’s disinfectant sprayers.
Shanghai alone had sterilised 13,000 areas as of Might 2 underneath a coverage focusing on contaminated individuals’s properties, house blocks and “preventative” disinfection of total compounds, vice-mayor Liu Duo mentioned.
The town has seethed for weeks underneath a shifting mosaic of lockdowns which have seen a few of its 25 million residents scuffle with police and unleash a flood of fury and frustration on social media.
In a single social media video verified by AFP, a hazmat-suited well being employee brandishing a strong hose sprays clouds of disinfectant on a resident’s mattress, desk and garments.
Different clips present staff wandering by streets and housing compounds, casually spritzing partitions, scooters — and even the bottom whereas residents line up for assessments.
One Shanghai resident instructed AFP his dwelling was sterilised twice after they returned from quarantine, together with his household being ordered to attend exterior for an hour every time.

Whereas the virus can transmit by surfaces, “it can not survive lengthy exterior the human physique, so it’s pointless to sterilise outside surfaces,” Huang from the Council on Overseas Relations mentioned.
“The widespread use of some chemical disinfectants, similar to chlorine disinfectant, may have dangerous impacts on human well being (and) the setting.”
Leong Hoe Nam, an infectious illness skilled at Singapore’s Mount Elizabeth Novena Hospital, mentioned outside disinfection was “completely pointless.”
“The Chinese language phrase is ‘drawing toes on a snake’ — superfluous,” he instructed AFP.
China’s refusal to waver on zero-Covid could also be driving the zealous use of sterilisers, mentioned Ben Cowling, a professor on the College of Hong Kong’s College of Public Well being.
Given the disruptive impression of sudden lockdowns, “one may see a rationale for utilizing each attainable method to cut back transmission,” he instructed AFP.
These could embrace methods that “might need near zero impact however may in uncommon circumstances forestall one an infection,” he added.
Leong mentioned the disinfection drive was largely “a variety of seen intervention that pleases directors” with out doing a lot to forestall Covid spreading.
However Beijing’s need to display its dedication to a flagship coverage was maybe the extra essential facet, Huang mentioned.
The transfer “conjures up the picture of a heroic battle in opposition to an invisible enemy,” he mentioned.
