Chinese authorities impose blood tests and release laboratory mosquitoes to combat the chikungunya epidemic | Laboratory

While the chikungunya epidemic continues to spread in China, the prevention and control measures imposed by the Chinese communist regime arouse growing concerns among health professionals and the Chinese public.

The province of Guangdong reported 1387 new cases of Chikungunya last week (from August 3 to 9), according to an opinion from the provincial centers for disease control and prevention. No deaths due to the virus has been reported to date, according to the Chinese agency.

According to the state media, on July 29, the cumulative number of cases of Chikungunya in Foshan, Guangdong, where the first cases of the epidemic were reported on July 8, exceeded 6000.

Due to the history of the Chinese communist regime in terms of censorship of the data which he considers politically sensitive-as we have seen with his concealment of infections by the COVID-19 and the deaths linked to it at the end of 2019-the actual number of known infections caused by chikungunya fever could be higher.

Chikungunya fever is a viral disease mainly transmitted to humans by mosquitoes. Its symptoms are similar to those of dengue. Patients usually have fever, strong joint pain, muscle pain, headache, fatigue and rashes.

There is no specific antiviral treatment against chikungunya. The deaths due to this disease are rare, but occur, especially among the vulnerable populations, especially those suffering from underlying health problems.

Globally, in July 2025, the Chikungunya fever resulted in 90 deaths in 16 countries and territories affected.

The epidemic in China started in the most affected city, Foshan. Confirmed cases have since been detected in more than ten cities in the province of Guangdong, according to the Provincial Center for the Control and Prevention of Guangdong Diseases.

The Macao health office reported a case of chikungunya fever on July 18. Hong Kong health authorities reported one case on August 2. The two cases were identified as children who had symptoms after their return from a trip to Foshan, according to local health authorities.

The Chikungunya virus has also spread in northern China. The Beijing Disease Control and Prevention Center issued a recall to caution on July 22, warning against occasional cases allegedly imported from abroad. However, the Beijing authorities have not published any data.

American centers for the control and prevention of diseases issued 1^is August a level 2 travel alert for China while the chikungunya virus epidemic continues to spread.

Chinese doctors and residents told Epoch Times that the virus had spread to more and more places in China.

A Chinese doctor whose work is linked to the prevention of diseases has spoken to Epoch Times August 10 under the cover of anonymity, for security reasons. The doctor said the chikungunya had spread to the megalopolis of Chongqing, in southwest China, as well as in the city of Wuhan, in the center of the country.

A resident declared in a video published on social networks that Chikungunya fever had spread to Hunan province, adjacent to Guangdong, and that a recording was required when buying any medication dealing with fever.

The Foshan municipal market surveillance office introduced sales control of 47 drugs to treat fever, rashes, joint pain and other symptoms caused by chikungunya in all retail pharmacies of the city, requiring a recording for any sale, according to an opinion published on August 4.

The Chinese regime has also imposed compulsory measures which have aroused fears of a return to draconian restrictions of the regime linked to the COVID-19, such as the compulsory quarantine self-funded and the PCR tests.

Local residents and health professionals have notably expressed their concern about the obligation to carry out PCR tests on blood samples to detect the chikungunya virus, which the diet has put forward in its public messages.

Mandatory blood tests

Residents of different localities in the province of Guangdong have published information on social media reporting on the implementation of compulsory blood tests for the screening of chikungunya by PCR, which differ from salivary tests for the COVVI-19.

A patient said in a video that after the hospital staff have taken three blood tubes for him, he was tested positive in chikungunya. He wonders why the hospital had to take three tubes to carry out tests.

The Chinese doctor, whose work is linked to disease prevention, explained that the chikungunya virus requires blood for PCR tests, as it is a blood -transmitted disease.

“Blood intakes are also used for tertiary surveillance, and the development of vaccines requires the isolation of blood toxins, so a relatively large amount of blood should be removed,” he said.

On August 9, a resident of the city of Guangzhou said on social networks that the staff of the Jiangnan Middle Street community office had gone home and demanded that the inhabitants submit to a blood test. He refused and a group of employees returned several times to demand it. Another resident of Guangdong revealed in a video posted on August 10 that the staff of the office of his community came at 10 p.m. to take a blood test for a PCR test on chikungunya.

The media of continental China reported that in the first hours of August 4, officials of the community office of the city of Zhanjiang, Guangdong, took power blood from two minors in the absence of their parents, causing the public’s indignation.

“The fact that civil servants of the Chinese government take advantage of the absence of parents to take blood from children constitutes a serious violation of medical ethics,” the partner of the partner of the partner ofEpoch Times) Sean Lin, assistant professor in the department of biomedical sciences of Feitian College and former microbiologist of the American army.

Based on reports of such brutal actions, Mr. Lin suspects that the Chinese regime “hides information on the possible presence of other pathogens in this epidemic in addition to chikungunya, because the mosquitoes of the Guangdong are bearers more than one infectious disease”.

According to Mr. Lin, the Public Health Department of the Chinese Communist Party should publish a report on research as soon as possible, in particular at the height of the epidemic.

“It is easy to catch a large number of mosquitoes for research to determine if other viruses circulate at the same time, which can save people with the pain of some forced forty and blood tests,” he explained.

The laboratory mosquito breeding program arouses concerns

The Chinese state media reported at the beginning of August that the largest breeding installation of Chinese mosquitoes, Wolbaki, located in the Huangpu district of the city of Guangzhou, worked at full speed and released 5 million male mosquitoes specially treated per week, in the hope that they mate with the population of wild female mosquitoes to produce non -viable eggs control of the population known as Wolbachia transinfection, where the reproductive compatibility of male mosquitoes is altered by infection by the Wolbachia bacteria, a common bacteria present in nature.

The founder of Wolbaki was the former director of the vectors’ control center for tropical diseases, another mosquito breeding center, at the Sun Yat-Sen university in Guangzhou, in partnership with the State University of Michigan, where Mr. Xi is a professor of microbiology, genetics and immunology.

“When male mosquitoes [infectés] Bearers of the Wolbachia bacteria mate with wild female mosquitoes that do not carry the bacteria, the eggs produced cannot develop normally due to cytoplasmic incompatibility and cannot hatch in mosquito larvae, “the Chinese media Gong Juntao, chief researcher of Wolbaki of Guangdong, told Mosquito.

However, this method has flaws: if infected laboratory females are not separated and are released in the wild, they can continue to reproduce and propagate the disease with success.

The company claims to have developed automated technology allowing to effectively separate male and female laboratory mosquitoes on the laboratory, with an error rate of less than 0.5 %. However, Mr. Lin said that given the significant number of released mosquitoes, an error rate of 0.5 % “means that around 25,000 female mosquitoes likely to transmit diseases are still released each week”.

In May, the Chinese media reported that the largest breeding installation of Chinese mosquitoes, located in the Huangpu district in Guangzhou and designated as the only research center on Chinese mosquitoes, conducted a pilot study aimed at producing 30 million male mosquitoes infected with the Wolbachia virus – nourished with sheep blood – in order to release them every month Prevention of diseases transmitted by mosquitoes and targeting dengue, zika and chikungunya viruses.

Two months later, China experienced its greatest epidemic in Chikungunya ever recorded.

China’s efforts to slow down the reproduction of wild mosquitoes using laboratory males in mass and infected by Wolbachia “failed twice,” said the Chinese doctor to Epoch Times.

He predicted that in the southern China’s southern and downtown, the number of mosquitoes carrying the Chikungunya virus will increase quickly before winter.
