The rapid spread of the chikungunya virus in southern China, centered in Guangdong province, has caused concern in recent days. According to the country's health authorities, more than 7.000 confirmed cases since early July, bringing back memories of the days of the Covid-19 pandemic, as strict containment and prevention measures are implemented.
The local authorities have marked red alert in more than a dozen cities, with intensive disinfections, travel restrictions, information campaigns and increased health control.
What is the chikungunya virus?
The virus chikungunya (Chikungunya) is a virus transmitted by mosquitoes, mainly from the species Aedes aegypti and Aedes albopictus, which are also found in areas with a warm and humid climate—such as in southern China.
The disease was first identified in 1952 in Tanzania and its name comes from the Maconte language, where it means "the one who bends", due to the intense musculoskeletal pain it causes in patients, who often have difficulty standing or moving.
How is it transmitted – What are the symptoms?
Transmission occurs when a mosquito bites an already infected person and then passes the virus to other people through new bites. It is not spread from person to person.
The common symptoms include:
-
Sudden fever
-
Severe joint pain
-
Myalgia and headache
-
Fatigue
-
Skin rash
-
In some cases, joint swelling and stiffness
Η duration of the disease is usually 7 to 14 days and in the majority of cases hospitalization is not required. Vulnerable groups, however, may require medical support to relieve symptoms.
Global concern and preventive measures
The outbreak of the virus in one of China's largest and most populous provinces is also causing concern for the World Health Organization, as it highlights the increased risk of tropical diseases which are amplified due to climate change and increased population mobility.
Chinese authorities are calling on citizens to:
-
To use mosquito repellents
-
Avoid standing water where mosquitoes breed
-
Wear long clothes
-
And to consult a doctor immediately if they experience the above symptoms
Risk of global spread?
Although the spread of the virus currently appears to be limited within China, experts point out that the global travel network and presence of the same mosquito species in many countries, make it possible for outbreaks to occur in other areas—as has happened in the past with other viral diseases, such as Zika and Dengue fever.
At present, there is no specific treatment or vaccine for the chikungunya virus, and management is mainly through analgesics and antipyretics.
Conclusion
The case of Guangdong highlights the need for enhanced surveillance and international cooperation in public health matters. Chikungunya virus is not a new global threat, but it is certainly a reminder that the next health crisis may begin from an “exotic” corner of the world—and to influence everyone.
