Malarial infections are often missed by microscopy, and most parasite carriers asymptomatic in low-endemicity settings. Whether detectability its ability to elicit symptoms change as transmission declines remains unclear.
Abstract Background Immunity after dengue virus (DENV) infection has been suggested to cross-protect from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and mortality. Methods We tested whether serologically proven prior DENV diagnosed in September–October 2019, before the disease 2019 (COVID-19) pandemic, reduced risk of SARS-CoV-2 clinically apparent COVID-19 over next 13 months a population-based cohort Amazonian Brazil. Mixed-effects multiple logistic regression analysis...
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Gamma variant has been hypothesized to cause more illness than previous variants, especially in children. Successive SARS-CoV-2 IgG serosurveys the Brazilian Amazon showed that age-specific attack rates and proportions of symptomatic infections were similar before after emergence.
Abstract Background Larvicides are typically applied to fixed and findable mosquito breeding sites, such as fish farming ponds used in commercial aquaculture, kill immature forms thereby reduce the size of adult malaria vector populations. However, there is little evidence suggesting that larviciding may suppress community-wide transmission outside Africa. Here, we tested whether biological larvicide VectoMax FG at monthly intervals can incidence Amazonian Brazil. Methods This study was...
This population-based open cohort study aims to investigate biological and sociodemographic drivers of malaria transmission in the main urban hotspot Amazonian Brazil.
Malaria remains common among native Amazonians, challenging Brazil's elimination efforts.We examined the epidemiology of malaria in riverine populations country's main hotspot - upper Juruá Valley Acre state, close to Brazil-Peru border, where Plasmodium vivax accounts for > 80% cases.Participants (n = 262) from 10 villages along Azul River were screened parasites by microscopy and genus-specific, cytochrome b (cytb) gene-based polymerase chain reaction. Positive samples further tested with...
Malaria is increasingly diagnosed in urban centers across the Amazon Basin. In this study, we combined repeated prevalence surveys over a 4-year period of household-based random sample 2,774 persons with parasite genotyping to investigate epidemiology malaria Mâncio Lima, main transmission hotspot Amazonian Brazil. We found that most malarial infections were asymptomatic and undetected by point-of-care microscopy. Our findings indicate as decreases, detection threshold microscopy rises,...
