On 6 December 2013, the Pan American Health Organization (PAHO) and the World Health Organization (WHO) reported confirmation of the first two cases of indigenous transmission of chikungunya fever (CHIK) in the Region of the Americas on the island of Sint Maarten (Netherlands Antilles). For the period 2013-2014, a total of 25 627 confirmed autochthonous cases were distributed in 43 countries, with Mexico reporting 155 cases in five states. Information on cases of CHIK in Mexico was obtained from the database of the General Directorate of Epidemiology (Ministry of Health of Mexico). The distribution of confirmed autochthonous cases of CHIK for 2015, by sex, was 64% female (5 583) and 36% male (3 085). The most frequent symptoms were fever in 98% of cases (8 564), followed by headache in 91.6% (7 941), myalgia in 89.9% (7 792), mild arthralgias in 73.5% (6 367), severe polyarthralgia in 72.6% (6 295), and exanthema in 58% (5 032). The clinical presentation of autochthonous cases of CHIK in Mexico has shown several clinical manifestations different from those seen in outbreaks in African and Asian countries and other regions in the Americas; for example, a greater percentage of cases with headache and myalgia and a smaller percentage of cases with arthralgia.
