Chikungunya is an infectious disease caused by a viral pathogen that is transmitted through the bite of mosquitoes, specifically the species Aedes aegypti and Aedes albopictus. Despite sharing the same insect bites as dengue fever, chikungunya is a distinct disease.

Fever and severe joint pain are the primary symptoms of chikungunya. Treatment of this condition focuses on the importance of adequate sleep, the consumption of large amounts of fluids to prevent dehydration, and the use of pain relievers, such as paracetamol. Is chikungunya a recurring infection?

The history of Chikungunya

Chikungunya is the result of infection with the Chikungunya virus (CHIKV). The initial discovery of this virus occurred in the Republic of Tanzania in 1952, after which it rapidly disseminated to several nations in Africa and Asia. Urban outbreaks were initially documented in Thailand in 1967 and then in India throughout the 1970s. This suggests that the virus has the capacity to quickly disseminate among human and mosquito populations.

The number of CHIKV epidemics has increased significantly since 2004. One of the contributing factors is the virus's adaptation, allowing it to be more easily transmitted by the Aedes albopictus mosquito, which has a broader geographical distribution than Aedes aegypti.

Transmission of CHIKV has stopped in certain regions due to the fact that the majority of the population has been infected and has developed immunity. However, transmission is still prevalent in regions where the majority of the population has not been exposed to the virus.

Main symptoms of Chikungunya

Symptoms of chikungunya infection typically manifest within 3–7 days of transmitting the virus through a mosquito bite. Among the symptoms that are generally experienced are:

• High fever
• Joint pain in various locations on the body, mostly in big joints like the knees, wrists, and feet

Additional symptoms that may be present include:

• Headache
• Muscle pain
• The swelling of specific joints
•  Reddish and raised rash
• Fatigue
• Pain behind the eyes

Is it possible for reinfection in Chikungunya?

Although mosquito bites are the primary method of transmission for both dengue fever and chikungunya, they are different diseases. In cases of dengue fever, people who were previously infected with the dengue virus are at risk of reinfection by a different serotype of the dengue virus. Typically, there are four primary serotypes of the dengue virus, namely DEN-1, DEN-2, DEN-3, and DEN-4.

The initial infection with one of the dengue virus serotypes provides lifelong immunity to that serotype. Nevertheless, the immunity that develops following the initial infection does not offer comprehensive protection against other serotypes.

In reality, people who have been previously infected with one serotype of the dengue virus are at risk of developing a more severe disease described as dengue fever (severe dengue or dengue hemorrhagic fever) when they are next exposed to a different serotype.

But chikungunya is different; research indicates that those who contract the virus may have lifetime immunity to it. The body typically creates antibodies that can successfully protect against re-infection with the same strain of the Chikungunya virus after an individual has been infected and recovered.

The body's antibodies, particularly those known as neutralizing antibodies, play a critical role in preventing the Chikungunya virus from invading and proliferating within the body's cells. They bind and neutralize viruses, thereby preventing their dissemination and the development of disease.

As a result, almost all people who survive a chikungunya infection develop strong immunity against being infected again by the same strain of this virus. Typically, this immunity is regarded as permanent.
