Report of First Outbreak of ZikaVirus from Kanpur Nagar, Uttar Pradesh, India

Abstract

The first laboratory-confirmed case of Zika virus disease was reported from Kanpur Nagar district of Uttar Pradesh in the month of October 2021. The index case of this outbreak was a male patient of 57 years of age and resident of Jakodia compound, Pokharpur, Kanpur Nagar (UP). The patient had been suffering from body aches for the last two days, high-grade fever for one day, redness and itching of eyes for two days and throat pain for two days. With these complaints, the patient went to the Seven Air Force Hospital, Kanpur on October 13, 2021. There was no past history of blood transfusion of the patient. Since the patient was not responding to treatment, different samples like serum, nasal swab and throat swab were sent to the National Institute of Virology (NIV), Pune where he was finally diagnosed with Zika virus disease. Neither the patient nor any family members had any past history of travel to any other state/ country for the last six months. Thus, this was the first case of ZIKV in the state from Kanpur Nagar district. A total of 5583 samples were collected between October 23, 2021 to December 22, 2021, out of which 142 samples were found positive for Zika virus, however, no major anomaly was detected in any of these Zika-positive cases. Containment zones were identified, and contact tracing and intensified entomological surveillance activities were carried out in these areas with the active participation of local urban bodies and the State Health Department. A total of 4329 numbers of contacts were traced, out of which 702 were primary contacts and 3627 were secondary contacts. In Entomological activities, a total of 91817 houses were searched and out of these 1262 houses were found positive for Aedes larvae breeding (H.I 1.37 %). A total of 692925 numbers of containers were searched from the affected area, out of which 1414 containers were found positive for Aedes breeding (C.I 0.20 % & B.I 1.54). This is the first outbreak of Zika virus from the state of Uttar Pradesh reported so far. There is an urgent need for intensified entomological surveillance and source reduction along with other vector control measures, community participation and IEC activities to prevent such outbreaks in future.
