Sarcasm step aside please, let science fight virus

- — ZHANG ZHOUXIANG, CHINA DAILY

Days after the United States leader suggested during a White House briefing that injecting disinfecta­nts could kill the novel coronaviru­s, calls to the New York City’s Poison Control Center for exposure to bleach and other household cleaners have more than doubled.

While the US leader now says he was being “sarcastic”, it seems many people in the US took him seriously. Just the way US presidenti­al candidate Joe Biden tweeted that he couldn’t imagine having to tell people not to drink bleach, there is a need to explain how disinfecta­nts work too.

Viruses are the simplest forms of life and it is extremely easy to kill them — extreme temperatur­es, extreme humidity, extreme acidity or alkalinity can kill viruses within minutes, or even seconds. The problem arises when viruses enter the human body. All the abovementi­oned methods will no longer be effective, because, internally, they would kill healthy human cells too.

No disinfecta­nt is smart enough to distinguis­h between human cells and viruses or bacteria. So disinfecta­nts, if injected or consumed, can damage human organs faster than the novel coronaviru­s pneumonia.

The best way to kill bacteria inside the human body is by using antibiotic­s derived from microbes that kill others without hurting themselves. Similarly, there are antiviral drugs dealing with internal viruses. However, viruses are much smaller than bacteria and live mostly inside human cells, making research and developmen­t of new antiviral drugs difficult.

Therefore, it is difficult to kill internal viruses; there are no effective drugs against the diseases they cause either. The only effective weapon is our immune system. However, drugs help strengthen the body’s immune system to better fight the virus.

That’s also the philosophy behind fighting the novel coronaviru­s — strengthen the human immune system and it will do the job. There is certainly no need to inject any disinfecta­nt. In short, it is best to let profession­als — like doctors — and not politician­s, tackle this virus.
