Virus Chikungunya in Colombia, a simple matter of time?

CHIKV was first isolated in 1953 in the serum of a patient in Tanzania during an epidemic of dengue. In a recent dendrogram, t h i s i s o l a t e appeared with the name of Ross low psg (1,2). The first clinical report of chikungunya was in Thailand between 1962 and 1964 (3). Between 1960 and 2003 CHIKV reemerged and spread in Southeast Asian countries such as India, Malaysia, Indonesia, Vietnam, and Thailand, among others. A Central African genotype has occurred since 2000 and spread to Europe, Asia, and Australia (4). From the clinical perspective, CHIKV may produce acute, sub-acute, or chronic illness. The acute phase is characterized by an abrupt onset with fever surpassing 39°C and severe joint pain. Polyarthralgia, headache, myalgia, back pain, nausea, vomiting, rash, and conjunctivitis are common; the duration of the acute phase is 3 to 10 days (5). Symptoms of CHIKV infection are similar to dengue.
