Study looking at death rates early in the pandemic confirms that low-income nations have born the brunt of the global disaster.
, is one of a growing number of studies to reveal COVID-19’s massive burden in lower-income countries.
In rich countries, older individuals — who are most vulnerable to the disease — were less likely to have been infected than young people. But the authors found that in most lower-income countries, the percentage of adults aged 60 and older who had antibodies against the coronavirus was similar to that of young people. This is probably because many people in these countries live in multigenerational households, which makes isolating from an infected person difficult, says Meyerowitz-Katz.
As COVID-19 vaccines have become available, the mortality gap between low- and high-income countries might have shrunk, Meyerowitz-Katz says. But it could also have widened, because many poorer nations still have limited access to vaccines. “It’s hard to know precisely how that’s changed over time,” he says. When vaccines were approved, wealthy nations hoarded them, which exacerbated the vaccine equity gap between rich and poor countries, says Pai.
