On March 24, 2020, we ran a news article about how warmer weather appeared to hamper COVID-19 infections.1 New evidence could indicate that high altitudes might limit the spread of the disease as well.
A recent report details how high-altitude populations appear to have a low COVID-19 infection rate.2 Only 916 of Peru’s 141,000 COVID-19 cases came from the Andean Cusco region—around 80% percent below the national average. Bolivia’s 8,387 COVID-19 cases have been mostly in Santa Cruz—just a few hundred feet above sea level—but high-altitude La Paz had just 410 cases.
The phenomenon is currently unexplained. A peer-reviewed study in Respiratory Physiology & Neurobiology, from Australia, Bolivia, Canada, and Switzerland, examined results from Bolivia, Ecuador, and Tibet. They found populations living at altitudes above 3,000 meters (9,850 feet) reported significantly lower levels of confirmed infections than low-altitude populations. People living at high altitudes might also benefit from an ability to cope with low levels of oxygen in their blood. Other conditions not strictly related to altitude that might also tend to limit spread of COVID-19 in this study include that these are sparsely populated areas, the air is drier, and there are higher levels of UV radiation.
A researcher noted that prolonged exposure to altitude triggers a chain reaction in the lungs involving a protein known as ACE2 that might prevent pulmonary shunting—a common problem among COVID-19 patients.
