What is Chikungunya?

Chikungunya is a mosquito-borne viral disease that causes fever and severe joint pain. It is caused by a ribonucleic acid (RNA) virus [5]. The name "chikungunya" means "bends you up" or "stooped walk" in the Makonde language, which refers to the symptoms of the disease [6].

Common Symptoms

The most common symptoms of chikungunya are fever and joint pain. Other symptoms can include headache, muscle pain, joint swelling, or rash [1]. The disease is characterized by an acute onset of fever (typically >39°C [102°F]) and polyarthralgia, which is the inflammation of multiple joints [9].

Transmission

Chikungunya is a virus that spreads through mosquito bites. There's no medication for it, and you can only manage your symptoms [4]. The disease has been associated with frequent outbreaks in tropical countries of Africa and Southeast Asia [8].

Key Points:

• Chikungunya is a mosquito-borne viral disease.
• Symptoms include fever, joint pain, headache, muscle pain, joint swelling, or rash.
• The disease is characterized by an acute onset of fever and polyarthralgia.
• Chikungunya spreads through mosquito bites.
• There's no medication for the disease.

Common symptoms of chikungunya infection

Chikungunya virus infection can cause a range of symptoms, which can vary in severity from person to person. The most common symptoms include:

• Fever: A high temperature is often one of the first signs of chikungunya infection.
• Joint pain: Severe joint and muscle pain

Diagnostic Tests for Chikungunya

Chikungunya diagnosis can be challenging due to its similarity in symptoms with other arbovirus infections such as dengue and Zika virus. However, several diagnostic tests are available to confirm the presence of the virus.

• Serologic tests: These tests detect the presence of antibodies against chikungunya virus in the blood. They typically take 5-7 days into the illness to turn positive [4][8].
• Enzyme-Linked-Immunosorbent-Assay (ELISA): This is a type of serologic test used to detect IgM and IgG antibodies against chikungunya virus [6][9].
• Indirect Fluorescent Antibody (IFA) technique: This method has good sensitivity and specificity for detecting CHIKV, but its use is limited due to the availability of ELISA tests [9].
• Laboratory diagnosis: This involves testing serum or plasma to detect virus, viral nucleic acid, or virus-specific immunoglobulin (Ig) M and neutralizing antibodies. Chikungunya virus disease is a nationally notifiable condition, and healthcare providers are encouraged to report suspected cases to their state or local health department [11].

It's essential to note that early diagnosis of chikungunya can be challenging due to the similarity in symptoms with other arbovirus infections. Therefore, a high index of clinical suspicion based on epidemiology and clinical presentation is crucial for making an accurate diagnosis.

Treatment Options for Chikungunya

Chikungunya, a viral disease transmitted by mosquitoes, can be managed with various treatment options to alleviate symptoms and improve quality of life.

• Pain Relief: Over-the-counter (OTC) pain medications such as aspirin, ibuprofen, and naproxen sodium are commonly used to relieve joint pain and fever [5]. These medications belong to the class of nonsteroidal anti-inflammatory drugs (NSAIDs), which can help reduce inflammation and alleviate symptoms.
• Symptomatic Treatment: Since there is no specific antiviral treatment for chikungunya, medical treatment focuses on managing symptoms such as pain, fever, and joint swelling [2][6]. This may include the use of analgesics and antipyretics to control pain and fever.
• Severe Arthralgia Management: In cases where severe arthralgia is present, nonsteroidal anti-inflammatory drugs (NSAIDs) can be used in conjunction with physiotherapy to manage symptoms [3].
• Pharmaceutical Therapies: Various pharmaceutical therapies have been explored for the treatment of chikungunya virus (CHIKV), including NSAIDs, methotrexate, chloroquine, and ribavirin [4].

It's essential to note that while these treatments can help alleviate symptoms, there is no specific antiviral drug treatment available for chikungunya. Treatment primarily focuses on managing symptoms and improving quality of life.
