The SARS-CoV-2 pandemic generated a significant burden of post-COVID-19 sequelae, including impaired pulmonary function and psychological morbidity. In Peru, community-level evidence on these sequelae remains scarce, particularly in rural settings. SUYAY TUMPIS is an observational open ambidirectional cohort study designed to determine pulmonary and psychological sequelae in COVID-19 survivors from urban and rural communities in the Tumbes region of northern Peru. A total of 270 adults (aged ≥18 years) with history of COVID-19 between 2020 and 2021 from Puerto Pizarro (rural) and AAHH Las Flores (peri-urban) will be enrolled, alongside 30 COVID-19-negative controls. Evaluations will be conducted at months 0, 6 (conditional), and 12. Pulmonary function will be assessed using portable spirometry (Datospir Aira-T: FVC, FEV1, FEV1/FVC, PEF) and non-contrast thoracic CT scan (SIEMENS SOMATO...

Objective: a) to assess the seroprevalence of SARS-CoV-2 at the end of the second wave; b) to determine the distribution by age group and health determinants associated with seropositivity. Material and Methodology: A study performed in a Tumbes' settlement between December 2021–January 2022 sampled individuals over 2 years old from one to every four households. We collected finger-prick blood samples and conducted symptom surveys. Results: The adjusted seroprevalence after the second wave increased by twofold (50.15%, 95% CI[45.92–54.40]), compared with the first wave (24.82 %, 95%CI [22.49–27.25]). Females maintained a higher seroprevalence (53.89; 95% CI[48.48-59.23]) vs. 45.49; 95% CI [38.98-52.12], p=0.042) compared to males. Those under 18 years of age had the highest IgG seropositivity: the 12–17 age group during the second wave (85.14%) and the 2–11 age group (25.25%) d...

Objetivo: a) evaluar la seroprevalencia de SARS-CoV-2 al final de la segunda ola; b) determinar su distribución por grupos de edad y los determinantes de salud asociados a la seropositividad. Materiales y Método: Un estudio realizado en un asentamiento humano de Tumbes entre diciembre de 2021 y enero de 2022 muestreó individuos mayores de 2 años en uno de cada cuatro hogares. Se tomó muestras de sangre por punción-digital y se realizó encuestas sintomáticas. Resultados: La seroprevalencia ajustada tras la segunda ola se duplicó (50.15%, IC 95% [45,92-54,40]), comparado con la primera ola (24.82%, IC 95% [22,49-27,25]). Las mujeres mantuvieron una mayor seroprevalencia (53.89; IC 95% [48,48-59,23] vs. 45.49; IC 95% [38,98-52,12], p = 0,042) comparado con los hombres. Los menores de 18 años presentaron mayor seropositividad IgG: el grupo de 12-17 años durante la segunda ola (85,...
