Background & objectives Q fever is an important zoonotic disease affecting humans as well as animals. The objective of this study was to assess the burden of Q fever in individuals with acute febrile illness, particularly those in close contact with animals. Various diagnostic methods were also evaluated in addition to clinical examination analysis and associated risk factors. ⋯ Interpretation & conclusions Q fever is underdiagnosed due to its varied clinical presentations, diagnostic complexities, and lack of awareness. This study underscores the importance of regular screening for Q fever in individuals with acute febrile illness, particularly those with animal exposure. Early diagnosis and increased awareness among healthcare professionals are essential for the timely management and prevention of chronic complications associated with Q fever.

Background & objectives Burden estimates of enteric fever are required to make policy decisions on introducing typhoid vaccine in India. Incidence, antimicrobial susceptibility, and out-of-pocket expenditure (OOPE) of enteric fever are estimated in Chandigarh, India. Methods A hybrid (facility and community-based) surveillance system was set up at a secondary care hospital to enrol patients above six months of age, hospitalized with fever, from a defined catchment population from May 2018 to March 2020. ⋯ Paratyphi [INR 8696.6 (USD 116)] was significantly higher than the individuals infected with S. Typhi [INR 7309 (USD 97.5), P=0.01], and among cases who were hospitalized for more than seven days [INR 12,251 (USD 163.3)] as compared with those with a stay of 3-7 days [INR 8038.2 (USD 107.2)] or less than three days [INR 5327.8 (USD 71), P<0.001]. Interpretation & conclusions There was a high incidence of enteric fever, high OOPE, and resistance to ciprofloxacin.

Background & objectives Presence of resistant gut flora in the community is associated with increasing multi-drug resistance (MDR) infections. In this study, the prevalence of MDR organisms in the gut flora of a healthy rural population residing in northern India was determined. Methods Healthy individuals aged 18-45 yr from Nuh district, Haryana, India were included in this study. ⋯ Resistance against fluoroquinolones was highest [92(48.7%)] among all isolates. Forty nine (25.9%), 25 (13.2%), 24 (12.7%) and 21 (11.1%) isolates, respectively were positive for blaTEM, blaSHV, blaCTXM-1 and OXA-48 genes. Interpretation & conclusions Overall the study findings suggest that 27 per cent individuals from rural northern India carry MDR organisms in their fecal flora, with an ESBL carriage rate of 44 per cent.

Background & objectives Genetic analysis of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) strains circulating in India during 2020-2022 was carried out to understand the evolution of potentially expanding and divergent clades. Methods SARS-CoV-2 sequences (n=612) randomly selected from among the sequences of samples collected through a nationwide network of Virus Research Diagnostic Laboratories during 2020 (n=1532) and Indian sequences available in Global Initiative on Sharing All Influenza Data during March 2020-March 2022 (n=53077), were analyzed using the phylo-geo haplotype network approach with reference to the Wuhan prototype sequence. Results On haplotype analysis, 420 haplotypes were revealed from 643 segregating sites among the sequences. ⋯ Interpretation & conclusions The haplotype analysis revealed that the G and GR clades were co-evolved and an epicentrefor the evolution of the GH, GK and GRA clades. GH was more frequently identified in northern parts of India than in other parts, whereas GK was detected less in north India than in other parts. Thus, the network analysis facilitated a detailed illustration of the pathways of evolution and circulation of SARS-CoV-2 variants.
