Chikungunya

Ckincal findings include fever usually presents with the non-specific findings of high-grade fever and myalgia, following a 3 to 7 day incubation period, and lasting around 3 to 5 days. Bilateral symmetrical polyarthralgia ensues 2 to 5 days after the onset of fevers and preferentially involves distal over proximal joints.The hands have been found to be affected the most with some involvement reported to the axial skeleton, knees, and ankles accompanied by intense pain that lasts between one and three weeks. Another common clinical manifestation is a generalized maculopapular rash that usually involves the extremities first and arises 3 days after the fever symptoms. Although rare, vesiculobullous and mucocutaneous lesions have also been reported.[1]

Manifestations such as abdominal pain, diarrhea, vomiting, and generalized lymphadenopathy may also be found. Although it is not considered to be a neurotropic virus, it has long been associated with neurologic symptoms, with encephalitis among newborns infected through mother-to-child transmission being the most common. In a 2018 study in Puerto Rico, red eyes, conjunctivitis, and anterior uveitis were frequently found in patients with Chikungunya fever. Other studies have described recurrent retinitis,[29] congenital ocular symptoms, sepsis/septic shock, and renal manifestations. [1]
