Genes that helped people survive during the time of the Black Death are more likely to be found in people with autoimmune diseases alive today. Does this tell scientists anything about what surviving the COVID-19 pandemic might mean for the world's population?

A 2022 study found that high blood pressure more than doubled the risk of being hospitalized from an Omicron-variant COVID-19 infection regardless of full vaccination, including a booster dose of an mRNA vaccine.

An estimated 30 million Americans experience some level of hearing loss, but only about 20% of them seek hearing aids. Many people can't accept they can't hear well, or won't act on symptoms. People should seek help if they have trouble hearing conversations, TV, and other sounds, and should see a doctor quickly if they have hearing loss in only one ear, pain, ear drainage, or vertigo. Visits with an audiologist and otolaryngologist (ear, nose, and throat doctor) are typically needed to get prescription hearing aids. Over-the-counter hearing aids are expected to be available online and in stores starting in late 2022.

Each year, millions of couples face one partner's serious diagnosis with a condition such as cancer, heart or kidney failure, or neurological illness, among others.

Life expectancy is one measure of the general health of a population. In the US, life expectancy had been climbing for more than a century — until the pandemic. After dropping in 2020, it dropped again in 2021, and some population groups fared worse than others.

Dry eye disease can redden eyes and make them sting, burn, or hurt. Relief may require a combination of strategies.
