Background: During the second wave of the COVID-19 pandemic, outbreaks of Zika were reported from Kerala, Uttar Pradesh, and Maharashtra, India in 2021. The Dengue and Chikungunya negative samples were retrospectively screened to determine the presence of the Zika virus from different geographical regions of India. Methods: During May to October 2021, the clinical samples of 1475 patients, across 13 states and a union territory of India were screened and re-tested for Dengue, Chikungunya and Zika by CDC Trioplex Real time RT-PCR. The Zika rRTPCR positive samples were further screened with anti-Zika IgM and Plaque Reduction Neutralization Test. Next generation sequencing was used for further molecular characterization. Results: The positivity was observed for Zika (67), Dengue (121), and Chikungunya (10) amongst screened cases. The co-infections of Dengue/Chikungunya, Dengue/Zika, and Dengue/Chikungunya/Zika were also observed. All Zika cases were symptomatic with fever (84%) and rash (78%) as major presenting symptoms. Of them, four patients had respiratory distress, one presented with seizures, and one with suspected microcephaly at birth. The Asian Lineage of Zika and all four serotypes of Dengue were found in circulation. Conclusion: Our study indicates the spread of the Zika virus to several states of India and an urgent need to strengthen its surveillance.

Introduction: Current study was carried out as per the government of India and Himachal Pradesh guidelines to carry out a serosurvey to assess the extent of COVID-19 infection among health care professionals (HCPs) after 6 months of managing COVID-19 cases. Methods: A hospital-based survey was carried out among 1279 conveniently selected HCPs from September 2020 to January 2021. Results: The participants had a mean age of 38.3 (±10.4) years, and almost half (47.4%) were ≤35 years of age. A total of 29 (2.3%) were already tested positive for COVID-19 (RT-PCR: 22; Rapid Antigen Test: 7) before the survey, and the overall prevalence of IgG antibody was 12.7% among the participants (Male: 12.8%; Females: 12.5%). The odds were observed significantly high among administrative staff (aOR: 5.09; 95%CI: 1.27-20.33) and participants tested positive of COVID-19 previously (aOR: 28.41; 95%CI: 11.71-69.00). Conclusion: HCPs were tested about 6 months after the initiation of the COVID-19 pandemic in the state and demonstrated a high and expected level of seroprevalence.
