Since the outbreak began, one question has left public health experts and scientists puzzled: Why does the virus provoke only mild symptoms in some people, while severely sickening others? | Since the outbreak began, one question has left public health experts and scientists puzzled: Why does the virus provoke only mild symptoms in some people, while severely sickening others? |
We think we know some of the factors. A person’s age has been shown to play a role, along with underlying conditions like diabetes, heart disease and obesity. Smoking may have a hand in the severity of an infection, too. | We think we know some of the factors.

European geneticists sequenced the genomes of infected patients in Italy and Spain who required an oxygen supply or a ventilator, to look for genetic traits that the patients shared. | European geneticists sequenced the genomes of infected patients in Italy and Spain who required an oxygen supply or a ventilator, to look for genetic traits that the patients shared. |
They found two commonalities. One is a person’s blood type. Patients with Type A blood had a 50 percent greater chance that they would need oxygen or a ventilator. | They found two commonalities.

The second factor showed an even stronger link to Covid-19, but it’s still a mystery. That’s because the spot in the genome that scientists homed in on has six genes, and they’re not sure which, exactly, is influencing the course of the virus. | The second factor showed an even stronger link to Covid-19, but it’s still a mystery.

Another head-scratcher is why blood type might play a role in a Covid-19 infection. One idea is that the location on the genome where blood type is determined also contains a stretch of DNA that can trigger strong immune responses. It’s possible that genetic variations may lead to an overreaction in the immune system, causing extensive inflammation and lung damage. | Another head-scratcher is why blood type might play a role in a Covid-19 infection.

Poverty as an underlying condition: The Times’ Opinion section found that conditions like kidney disease and diabetes are much more prevalent among the lowest income earners in the United States — potentially making Covid-19 more deadly among the poor. | Poverty as an underlying condition: The Times’ Opinion section found that conditions like kidney disease and diabetes are much more prevalent among the lowest income earners in the United States — potentially making Covid-19 more deadly among the poor. |

Even while doctors battle Covid-19, many are worried about another looming global public health threat: antimicrobial resistance. | Even while doctors battle Covid-19, many are worried about another looming global public health threat: antimicrobial resistance. |
Some 700,000 people die each year because medicines that once cured their conditions are no longer effective. As the pipeline for new drugs runs dry, health experts are warning that the same government inaction that allowed the coronavirus to spread worldwide could lead to an even deadlier epidemic of drug-resistant infections. | Some 700,000 people die each year because medicines that once cured their conditions are no longer effective.

Our colleague Andrew Jacobs, who covers health and science, writes that the problem comes down to economics: It costs billions to develop a new drug, but pharmaceutical companies haven’t yet figured out a way to profit off them. | Our colleague Andrew Jacobs, who covers health and science, writes that the problem comes down to economics: It costs billions to develop a new drug, but pharmaceutical companies haven’t yet figured out a way to profit off them. |
While the pandemic ebbs in some of the countries that were hit hard early on, the global case count is growing faster than ever. Here are a few places suffering particularly bad outbreaks right now. | While the pandemic ebbs in some of the countries that were hit hard early on, the global case count is growing faster than ever.
