New Virus: Chikungunya Outbreak Triggers Health Alert in China

China is currently dealing with a chikungunya virus outbreak, with more than 7,000 infections reported in Guangdong province since July.

The mosquito-borne disease has prompted health officials to implement strict control measures similar to those used during the COVID-19 pandemic.

The city of Foshan has been the most affected, and authorities there have introduced hospital-based isolation for infected patients. Individuals diagnosed with chikungunya must stay in hospital beds covered with mosquito nets and are only allowed to leave after testing negative or completing a mandatory seven-day stay.

Chikungunya is spread by the bite of infected mosquitoes and is known to cause high fever and intense joint pain, which in some cases can persist for months or even years.

Though not commonly seen in China, chikungunya is widespread in parts of Africa, South Asia, and Southeast Asia.

What Is Chikungunya?

People infected with chikungunya usually show symptoms within 3 to 7 days after being bitten. Common signs include fever, joint swelling, muscle aches, rashes, and headaches. Most recover within a week, but in severe cases, joint pain can linger for extended periods.

Those most at risk of complications include infants, older adults, and individuals with chronic health issues such as diabetes or heart conditions. While there is no specific treatment or cure, fatal outcomes are extremely rare.

The chikungunya virus was first identified in Tanzania in 1952 and has since been found in over 110 countries worldwide.

To control its spread, the World Health Organisation advises eliminating standing water, where mosquitoes typically breed.
