Overview
Chikungunya that follows a bite of an infected mosquito Aedes aegypti or Aedes albopictus carrying chikungunya virus, can either present as an asymptomatic or as a symptomatic disease.
The common symptoms of chikungunya include fever, petechial or maculopapular rash and arthralgia or polyarthritis.
Symptoms
While a proportion of individuals infected with chikungunya virus become asymptomatic (around 3-28%),[1][2] most of them will develop some symptoms after an incubation period of 3-7 days (range: 1-12 days). The symptoms of the disease can manifest as any of the following clinical forms.
Acute Disease
The following are the acute symptoms that usually last for 3–10 days.
- High fever: High fever is the most characteristic acute symptom. It is usually
- Sudden in onset.
- Lasts from several days up to a week.
- Typically >39°C [102°F].
- Continuous or intermittent.
- May be associated with relative bradycardia.
- Polyarthritis: Polyarthritis is another characteristic acute symptom of the disease that follows fever. Polyarthritis is usually
- Symmetrical.
- Affects 10 or >10 joint groups.
- Most commonly involves the hands and feet, but can also affect the proximal joints.
- Associated with tenosynovitis.
- Severe and debilitating, confining the patients to bed and thus affecting their normal day to day activities.
- Rash: Half the patients are affected by rash that usually occurs 2-5 days after the onset of fever. The rashes are
- Typically maculopapular.
- Involve the trunk and extremities, and can also include the palms, soles, and face.
- Can also manifest as diffuse erythema that blanches with pressure.
- Vesiculobullous lesions, the most common skin presentation in infants.
- Other symptoms may include headache, myalgia, conjunctivitis, nausea, vomiting, and diffuse back pain.
Subacute and Chronic Disease
Subacute and chronic disease can manifest as any of the following after an acute stage.
- Swollen and stiff joints
- Swollen joints with fine desquamation
- Hyperpigmentation
- Tenosynovitis
- Hygroma
Atypical Manifestations
Besides the typical symptoms, the disease can atypically present with any of the following clinical manifestations due to the virus itself, immunological response to the virus, or drug toxicity.[3]

- Ischemic heart disease
- Hemodynamic instability
- Skin:

- Vesiculobullous dermatosis
- Renal:

- Neonatal infection with vertical transmission:
- Ante-partum fetal deaths

- Other possible associations:
- Pneumonia
