Russia has created a rapid diagnostic tool for plague and cholera
In a significant development, China is currently grappling with an intense outbreak of Chikungunya fever, primarily concentrated in Guangdong Province, particularly Foshan city and surrounding areas [1][3]. Over 8,000 confirmed cases have been reported, making it the largest documented outbreak in China to date. The outbreak, which started in mid-June 2025, has peaked around mid-July, prompting aggressive containment efforts including quarantines, drone-based mosquito control, and legal enforcement to reduce mosquito populations.
Meanwhile, the potential risk of Chikungunya infection import to Russia is a cause for concern. Although there are no direct reports of cases in Russia so far, the risk exists due to travel and climate-related expansion of mosquito vectors. The Aedes mosquitoes that transmit chikungunya are expanding their range globally due to warmer temperatures and increasing rainfall, increasing the risk that infected travelers returning from affected areas like Guangdong could introduce the virus to Russian regions where competent mosquito vectors exist or could establish [2].
To mitigate this risk, health authorities recommend traveler vaccination, insect precautions (repellents, clothing, nets), and close monitoring. The development and implementation of such solutions are considered an important step towards enhancing public health safety in Russia.
On a positive note, the epidemiological situation in Russia remains stable. However, the risks of infection import from abroad persist, making preventive measures crucial.
In a separate development, a new test has been designed to detect pathogens of dangerous infections, including Chikungunya, within an hour [4]. This test, part of the federal project "Sanitary Shield of the Country - Safety for Health (Prevention, Identification, Response)", opens new horizons for examining contacts and preventing disease outbreaks. With high accuracy and the ability to detect even minimal microbial cells, the test could potentially aid in preventing disease outbreaks and effective control over infectious diseases in the country.
