Seroprevalence of COVID-19 in Carabayllo Peru
<div> <div> <div> <div> <p><strong>Objectives:</strong> To measure the SARS-CoV-2 seroprevalence in the Carabayllo district of Lima, Peru at the end of the first wave of the pandemic.</p> <p><strong>Methods:</strong> This was a cross-sectional study of the district with random bi-stage cluster sampling. We collected socio-demographic and clinical data as well as serum samples for SARS-CoV2 antibody testing.</p> <p><strong>Results:</strong> Among 2,014 subjects sampled, 59.93% were men. SAR-CoV-2 seropositivity was 24.88% (501/2014), and after adjusting for the sampling design effects and test performance, the seroprevalence in November/December 2020 was 22.4% (95% CI 22.35 - 27.63). Seropositivity varied by age, with participants aged 30-59 years old having the highest prevalence. Seropositivity in symptomatic patients (32%) was 1.5 times more than in asymptomatic ones (23%), and work away of home, age >18, COVID-19 home contact, obesity were risk factors of SARS-CoV-2.</p> <p><strong>Conclusions:</strong> The low seroprevalence after the first wave of pandemic in this community indicates that a high proportion of people remained susceptible. Infection was important among people who never reported symptoms. People with obesity had a higher risk of having SARS-Cov-2 infection.</p> </div> </div> </div> </div>

Data from: Risk factors associated to a high Mycobacterium tuberculosis complex seroprevalence in wild boar (Sus scrofa) from a low bovine tuberculosis prevalence area
<p>Animal tuberculosis is a worldwide zoonotic disease caused principally by <i>Mycobacterium bovis,</i> a member of the <i>Mycobacterium tuberculosis complex </i>(MTC). In southern Iberian peninsula, wild reservoirs such as the wild boar, among other factors, have prevented the eradication of bovine tuberculosis. However, most of the studies have been focused on south-central Spain, where the prevalence of tuberculosis is high among wild ungulates and cattle herds. In northern regions, where wild boar density and bovine tuberculosis prevalence are lower, fewer studies have been carried out and the role of this species is still under debate. The aim of this study was to describe the temporal and spatial distribution of antibodies against MTC in wild boar from the Basque Country, northern Spain. Sera from 1902 animals were collected between 2010 and 2016. The seroprevalence was determined with an in house enzyme-linked immunosorbent assay and the search of risk factors was assessed by Generalized Linear Models. Overall, 17% of wild boars (326/1902; 95%CI, [15.5%–18.9%]) showed antibodies against MTC. Risk factors associated with seropositivity were the year and location of sampling, the number of MTC positive cattle, the distance to positive farms and the percentage of shrub cover. Age was associated with increased antibody titres among seropositive individuals. The seroprevalence detected was higher than those previously reported in neighbouring regions. Hence, further studies are needed to better understand the role of wild boar in the epidemiology of tuberculosis in low tuberculosis prevalence areas and consequently, its relevance when developing control strategies.</p>
