Decreased incidence, virus transmission capacity, and severity of COVID-19 at altitude on the American continent.

The coronavirus disease 2019 (COVID-19) outbreak in North, Central, and South America has become the epicenter of the current pandemic. We have suggested previously that the infection rate of this virus might be lower in people living at high altitude (over 2,500 m) compared to that in the lowlands. Based on data from official sources, we performed a new epidemiological analysis of the development of the pandemic in 23 countries on the American continent as of May 23, 2020. Our results confirm our previous finding, further showing that the incidence of COVID-19 on the American continent decreases significantly starting at 1,000 m above sea level (masl). Moreover, epidemiological modeling indicates that the virus transmission rate is lower in the highlands (>1,000 masl) than in the lowlands (<1,000 masl). Finally, evaluating the differences in the recovery percentage of patients, the death-to-case ratio, and the theoretical fraction of undiagnosed cases, we found that the severity of COVID-19 is also decreased above 1,000 m. We conclude that the impact of the COVID-19 decreases significantly with altitude.

COVID-19 impact on people with diabetes in South and Central America (SACA region).

AIMS: The present observational study aims to describe political actions in place to combat COVID-19 in the South and Central America region (SACA) while protecting individuals with diabetes. METHODS: A survey with 12 questions was shared with all IDF-SACA member organizations, in 18 countries. A descriptive analysis was performed and a multivariate cluster analysis technique pam (partitioning around medoids) was applied. RESULTS: Two groups of countries were identified. The first group, mostly countries with stricter measures to contain the spread of the virus, reported more difficulties (limitations in accessing basic or health needs) and fears (concerns regarding the impact of the pandemic); whereas most of the second group consisted of countries with less restrictive measures, and reported fewer difficulties. Only 37% responded that a policy was put into place to protect individuals with diabetes, either delivering their medicines and supplies at home (16%) or providing them at once enough for 2-3 months (21%). All respondents reported that one of the main fear was to "be infected and not to receive adequate treatment" and/or "getting infected if going to the hospital or medical appointments". CONCLUSION: Most of the SACA countries failed to implement timely measures to protect individuals with diabetes, which may severely impact individuals, health systems and economies.
