Objective: Kyasanur Forest Disease (KFD) is a viral zoonosis reported from Karnataka, India. We investigated cases in the Shivamogga district, Karnataka, to describe the epidemiology and identify risk factors in the affected block in 2022.

Methods: A case was defined as a laboratory-confirmed KFD-positive resident of Shivamogga from 1 January-31 May 2022.

Background: India experienced three coronavirus disease (COVID-19) waves, with the third attributed to the highly contagious Omicron variant. Before the national vaccination rollout for children above 6, understanding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) positivity in the pediatric population was essential. This study aims to assess the burden of Covid-19 infection and to estimate the seroprevalence in children aged 6 to 14 years in the state of Karnataka.

The study reports the trend of coronavirus disease 2019 (COVID-19) infection observed from 2020 to 2022 in the city of Bengaluru, Karnataka, India, across each week in relation to the corresponding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sewage positivity data and other non-COVID-19 respiratory viral infections such as influenza and respiratory syncytial virus (RSV). The data on COVID-19 cases were procured from public domains, whereas the molecular testing of sewage samples and clinical samples for influenza and RSV was performed at our unit. The pattern of sewage positivity matched the waves of COVID-19, and few sewage samples in 2021 and 2022 tested positive before the onset of clinical cases.

Objective: To estimate the burden of active infection and anti-SARS-CoV-2 IgG antibodies in Karnataka, India, and to assess variation across geographical regions and risk groups.

Methods: A cross-sectional survey of 16,416 people covering three risk groups was conducted between 3-16 September 2020 using the state of Karnataka's infrastructure of 290 healthcare facilities across all 30 districts. Participants were further classified into risk subgroups and sampled using stratified sampling.
