On 27 November 2015, the National IHR Focal Point of Venezuela received notification of 7 suspected cases of Zika virus infection. The diagnoses were made by the national reference laboratory, the "Rafael Rangel" National Institute of Hygiene. Four samples tested positive for Zika virus by reverse transcription polymerase chain reaction (RT-PCR). The results were re-confirmed by Colombia’s National Institute of Health (INS). The cases, whose age ranges from 40 to 55 years old, are all women from areas that border Brazil. Venezuelan health authorities are implementing prevention and control measures. Investigations are ongoing.
