Abstract:Elsevier has created a COVID-19 resource centre with free information in English and Mandarin on the novel coronavirus COVID-19. The COVID-19 resource centre is hosted on Elsevier Connect, the company's public news and information website. Elsevier hereby grants permission to make all its COVID-19-related research that is available on the COVID-19 resource centre-including this research content-immediately available in PubMed Central and other publicly funded repositories, such as the WHO COVID database with r… Show more
“…Previous studies indicate the association between altitude and COVID-19 infection (Arias-Reyes et al, 2020;Segovia-Juarez et al, 2020). Our results give additional information about effect of altitude and population density on COVID-19 infection in a follow-up period of weeks from the first reported case in each region, which is important because of the unequal propagation of COVID-19 cases to altitude regions.…”
I t has been observed that COVID-19 infection decreases in high-altitude regions (Arias-Reyes et al., 2020; Segovia-Juarez et al., 2020). However, the interaction between altitude and COVID-19 infection has not been examined in a follow-up study since the first case reported in each region. Therefore, our aim was to evaluate the influence of altitude and population density on the evolution of case fatality rate (CFR) and prevalence of COVID-19 in Peru. An ecological study was carried out. The observation units were the geographic regions. The dependent variables were the COVID-19 CFR (deaths per 100 COVID-19 cases) and prevalence (cases per 1,000 inhabitants), covariables were the altitude (meters) and population density (inhabitants per km 2). The number of COVID-19-positive cases and deaths were obtained from the COVID-19 National Open Data

“…8 However, other studies reported that elevated altitude does not induce a decrease in the COVID-19 case fatality rate. 9,10 Considering this background, we decided to examine the scenario of positive cases, deaths, and the case fatality rate of COVID-19 in Colombia in an altitude range from 1 to 3,180 m above sea level. Data from 70 municipalities affected by the pandemic were used, including the 32 departmental capital cities of the country.…”
It has been suggested that high altitude can reduce the infectivity and case fatality rate of COVID-19. We investigated the relationship between altitude and the COVID-19 pandemic in Colombia. Epidemiological data included the number of positive cases, deaths, and the case fatality rate of COVID-19. In particular, we analyzed data from 70 cities with altitudes between 1 and 3,180 m. Correlations and linear regression models adjusted to population density were performed to examine the relationship and contribution of altitude to epidemiological variables. The case fatality rate was negatively correlated with the altitude of the cities. The incidence of cases and deaths from COVID-19 had an apparent correlation with altitude; however, these variables were better explained by population density. In general, these findings suggest that living at high altitude can reduce the impact of COVID-19, especially the case fatality rate.
“…We have read with interest the short communication published by Segovia-Juarez et al, 2020 in Respiratory Physiology & Neurobiology establishing that high altitude reduces the infection rate of COVID-19 but not the case fatality rate in the Peruvian setting. We support this hypothesis, however there could be an important number of under registered deaths on account of a low rate of diagnostic tests performed per inhabitant and mostly in symptomatic patients ( Pasquariello and Stranges, 2020 ).…”

“…Moreover, we used district altitudes in our analysis because Peruvian geography is greatly variable, and within a single province there may be a great difference between the altitude of different cities and towns. Hence, we believe a district altitude-based approach reduces the bias that may arise by altitude variability, which characterizes the province altitude-based approach used by Segovia-Juarez et al, 2020 Fig. 1 Correlation between excess mortality rate and altitude.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
