World Health Organization (WHO) announced today that it has certified China malaria-free, joining 40 other countries and territories globally.
Chinese government made malaria eradication a national priority under the 2010 National Malaria Elimination Action Plan.
“Today we congratulate the people of China on ridding the country of malaria,” said Tedros Adhanom Ghebreyesus, the director-general of the WHO, of the disease that killed 409,000 people globally in 2019.
“Their success was hard-earned and came only after decades of targeted and sustained action.” China becomes the first country of 37 in the WHO’s western Pacific region to rid itself of locally transmitted malaria in more than 30 years.
How China eradicate malaria
In 2010, the Chinese government committed to eradicating locally transmitted malaria within a decade. Chinese government pioneered a method known as “1-3-7,” which shortened the amount of time it takes for local health authorities to report malaria cases and begin to test others for exposure to the Plasmodium parasite. And in 2015 a Chinese scientist, Tu Youyou, was awarded a Nobel prize for her discovery in the 1970s of the anti-malaria drug artemisinin.
However China, like other countries, is vulnerable to a reemergence of malaria. It borders three countries where malaria is endemic (Laos, Myanmar, and Vietnam), and there is a risk that Chinese workers returning from Africa could bring the disease back with them. To keep its malaria-free status, China will have to submit a report to the WHO every year to prove that indigenous cases of malaria haven’t re-emerged.
What other countries are malaria-free?
The WHO has certified 100 countries or territories as malaria-free, but only 40 of those eradicated the disease through specific public health measures; the rest are places “where malaria never existed or disappeared without specific measures.”
How to qualify as malaria free country
A country is eligible to apply for an official certification of malaria elimination from the WHO if:
* It “has demonstrated—with rigorous, credible evidence—that the chain of indigenous malaria transmission by Anopheles mosquitoes has been interrupted nationwide for at least the past three consecutive years.”
*It has demonstrated “the capacity to prevent the re-establishment of transmission.”
China applied for the certification in 2020 by submitting evidence to the WHO in a report. An independent panel conducted field visits in China this year to verify the information in the report, and check what measures it has put in place to prevent malaria from coming back. The panel then made recommendations to the WHO director-general, who made the final call.
