[NTDTV, Beijing time, July 18, 2022]Many places in China are still implementing epidemic prevention measures such as lockdown and nucleic acid testing in high temperature weather. The team of Professor Zhang Wenhong from Huashan Hospital Affiliated to Fudan University in Shanghai recently issued a document objecting to the continued wearing of protective clothing (commonly known as Dabai) for epidemic prevention personnel in the sweltering heat, which caused heated discussions.
On the morning of July 16, Zhang Wenhong’s team posted on its Weibo account “Huashan Infection” that the weather has been extremely hot recently, and epidemic prevention personnel wear “big white”, which greatly increases the risk of heat stroke, because “big white” will prevent the heat dissipation of the human body. .
On February 20, 2022, Tan Swee Ching, an assistant professor at the National University of Singapore, published a research article in the academic journal “Small” and pointed out, “Health care workers who wear protective clothing and work for one hour at room temperature of 35°C usually You’ll feel a body temperature of about 64°C.”
The article “Huashan Infection” stated that wearing protective clothing at high temperatures can easily lead to heat stroke. Heat stroke is usually divided into heat cramps, heat exhaustion, and heat stroke. Severe heat stroke – heat stroke is a fatal emergency, with a lot of cold sweat in the early stage, followed by no sweat, shallow breathing, rapid pulse, restlessness, confusion, drop in blood pressure, and gradually develop to coma with limb convulsions; severe It can cause cerebral edema, pulmonary edema, heart failure, etc., and may even be life-threatening.
The article pointed out that a “big white” soaked in sweat has greatly reduced its protective effect. It is recommended that when sampling of the general population is carried out in an environment without air conditioning, in principle, the staff can prevent infection as long as the “level +” protective measures are taken, and they should wear N95 masks and face shields when they are in close contact with each other. Big White”.
“As for ordinary epidemic prevention workers (non-sampling personnel), especially in the outdoor environment in hot summer, we recommend wearing masks correctly and paying attention to hand hygiene,” the article reads.
The above suggestions have caused heated discussions on the Internet. Some netizens said: “It is already very uncomfortable to wear n95 (masks) in such a hot day. It is indeed impossible to wear white, which is not good for health.”
“Most parts of the country are now hot, and it’s hard for us ordinary people to stand outside for an hour, not to mention those staff in white, who ask for facts and can’t be one-size-fits-all.”
Some netizens also ridiculed: “If you don’t wear white, you won’t be able to scare the virus, there’s no sense of majesty, and there’s no educational significance.”
Before Zhang Wenhong’s team issued a popular science article on “don’t wear big white”, there were many cases of epidemic prevention personnel fainting from heat stroke. On July 14, a medical staff in Nanchang, Jiangxi Province was sent to the hospital for heat stroke because they were wearing “big white” and engaged in nucleic acid testing at a high temperature of 38°C.
A video posted online showed a nurse suffering from heat stroke lying on a bed in the emergency room, her limbs twitching. “It’s a seizure symptom,” said a surgeon. “It means that her brain has been thermally damaged. In this patient, even if it can be rescued, the patient’s brain damage is irreversible.”
Recently, there have been cases of death due to high temperature and heatstroke all over China, and “heat stroke” has also been searched on Weibo. At the same time, the mutant strain of Omicron continued to spread across China. The CCP authorities insisted on implementing measures to prevent and control the virus, as well as large-scale nucleic acid testing. Epidemic prevention personnel and ordinary people had to endure nucleic acid sampling in extreme heat.
