Aim: Chicken astroviruses (CAstV) are known to cause mild gastroenteritis, growth depression, and even mortality in poultry, especially in chickens, turkeys, and ducks. To the best our knowledge, there is no published information on CAstV in Grenada. This study was conducted to determine the prevalence of astrovirus in chickens in Grenada.
Materials And Methods: Blood samples from 366 indigenous chickens and 92 commercial chicken layers were collected from all parishes of the island and tested for antibodies against CAstV using commercial enzyme-linked immunosorbent assay.
Results: The seroprevalence of antibodies against astrovirus was 57.6% (95%, Confidence interval [CI]: 47.4-67.2) in commercial layers and 61.5% (95%, CI: 56.4-66.3) in indigenous chickens. The results show the presence of infection throughout the island.
Conclusion: The results show the infection with CAstV in approximately half of the chicken population in Grenada. This is the first report on the prevalence of CAstV in chickens in Grenada and the Caribbean region.

Hantavirus antibody seroprevalence and risk factors among adults in West Kazakhstan, 2023.
Front Public Health

Background: Orthohantaviruses (also known as hantaviruses) are pathogens, primarily transmitted by rodents, that can cause hemorrhagic fever with renal syndrome (HFRS). In endemic regions of Kazakhstan, no confirmed HFRS cases were detected between 2020 and 2022 raising concerns about detection. Estimate antibody seroprevalence for hantaviruses and identify associated risk factors among high-risk adults in western Kazakhstan in 2023.

Introduction: The tools to distinguish relapse from reinfection are needed in malaria-endemic areas. We evaluated seroprevalence against sets of specific peptides to the block 2 region of -merozoite surface protein-1 (PvMSP1) to detect parasite clones.
Methods: We applied amplicon deep sequencing (ADS) of block 2 region of the MSP-1 gene () to determine cocirculating parasite clones within eight -infected individuals.
Sensitivity of anti-filarial antibodies for lymphatic filariasis surveillance: Insights from a serological survey in Samoa in 2018.

Background: Sensitive diagnostic tools that signal lymphatic filariasis (LF) transmission are needed to monitor the progress of LF elimination programs. Anti-filarial antibody (Ab) markers could be more sensitive than antigen (Ag) point-of-care tests for monitoring LF transmission in some settings. This study aimed to investigate the sensitivity of anti-filarial Abs for detecting signals of LF transmission in Samoa by i) investigating the sensitivity and specificity of Ab to identify Ag-positives; ii) estimating the average number needed to test (NNTestav) to identify LF-seropositives (seropositive for Ag and/or any Ab), and iii) compare the efficiency of the different serological indicators by target age group and sampling design.

Background: Hepatitis C virus (HCV) has emerged as a sexually transmitted infection in gay, bisexual, and other men who have sex with men (GBM). We estimated the seroprevalence and incidence of HCV infection and examined patterns of HCV testing among GBM using human immunodeficiency virus preexposure prophylaxis (PrEP) in Ontario, Canada.
Methods: We analyzed data from the Ontario PrEP Cohort Study (ON-PrEP), a prospective cohort of PrEP users from 10 Ontario clinics.
Mechanistic models of humoral kinetics following COVID-19 vaccination.

COVID-19 vaccine programmes must account for variable immune responses and waning protection. Existing descriptions of antibody responses to COVID-19 vaccination convey limited information about the mechanisms of antibody production and maintenance. We describe antibody dynamics after COVID-19 vaccination with two biologically motivated mathematical models.
