More men than women appear to be dying from coronavirus

Smoking, drinking, general poor health: Researchers say these are some of the factors that could explain why more men seem to be dying from coronavirus than women.

In countries such as Italy, men represent nearly 60% of people who tested positive for the virus and more than 70% of those who have died, according to the country’s National Health Institute (ISS). Even in countries like South Korea, where the proportion of women who have tested positive for the virus is higher than that of men, about 54% of the reported deaths are among men.

But while health officials are starting to take note of these staggering numbers, the United States is not releasing the basic nationwide data that is crucial to understanding who is most vulnerable to the virus, according to a CNN analysis.

Dr. Deborah Birx, the White House’s coronavirus response coordinator, said at a White House press briefing on Friday: “From Italy we’re seeing another concerning trend. That the mortality in males seems to be twice in every age group of females.”

Regarding this data on Italy, Birx said in an interview with CNN’s Wolf Blitzer: “Just having the knowledge of that helps us in the United States so we can be very specific in talking to the American people about who to protect and how to protect them.”

CNN has reached out to Birx for additional comment.

When CNN asked the US Centers for Disease Control and Prevention for data split by sex for US cases of coronavirus and deaths by coronavirus, known as sex-disaggregated data, the CDC did not respond.

Comprehensive data about those who have gotten sick could help inform more effective responses to the crisis. But public health researchers say that when governments such as the United States either don’t collect, or don’t publish their data, it’s impossible for experts to gain an accurate sense of what’s going on.

Data divided by sex

In collaboration with Global Health 50/50, a research institute examining gender inequality in global health, CNN analyzed the publicly available data from 20 countries with the highest number of confirmed cases of Covid-19 at the time of data collection — March 20.

The aim was to see why men seem to be dying more than women.

From these 20 countries, only six provided data broken down by sex for both confirmed cases and deaths – China, France, Germany, Iran, Italy and South Korea. A further seven provided such data for the number of confirmed cases only. No sex-disaggregated data could be located for the remaining countries. The research has been submitted for publication and has not yet been peer-reviewed.

The data is not comprehensive in all cases: For example, the figures for China only cover the period through the end of February, well before community spread approached zero. And no reliable data exists on the proportion of tests administered to men versus women in any country. Furthermore, there are undoubtedly cases of the virus that are not reflected in the national data for any country.

But across the countries for which we have data – spanning nearly a quarter of the world’s population – we found that men were 50% more likely than women to die after being diagnosed with Covid-19.

While necessarily partial and incomplete, the results highlight what public health experts have been warning for some time, theorizing that it is not only biology but also gendered behaviors — the different ways in which men and women conduct their lives — which may play a significant role in the different mortality rate for respiratory diseases.

“When we look at the data what we’re seeing is that in every country with sex-disaggregated data … there is between a 10% and 90% higher rate of mortality amongst people diagnosed with Covid if they are men compared to if they are women,” says Sarah Hawkes, professor of global public health at University College London (UCL) and co-director of Global Health 50/50.

“If I was designing clinical guidelines, I would very much want to understand why some people seem to have a much higher risk of mortality than others. It might for example lead to a difference in the way in which we administer clinical guidelines amongst people who have pre-existing health conditions that lead to risk of death along with those with chronic lung disease, who are more likely to be men.”

Hawkes also noted that reporting sex-disaggregated data on epidemics has been requested by the World Health Organization since 2007, but many countries fail to do so.

As the US data was not publicly available on a national level, CNN went state by state to request the data, but many did not release it. Even states such as New York and California, where the outbreak is particularly severe, did not provide CNN with the requested data, despite several attempts. In some cases, CNN located the data in press releases from local counties, care homes and hospitals.

“I’m pretty sure that in a country with the sophistication of the health system and the surveillance system that the United States has, that it’s not that there’s an absence of data,” says Hawkes.

“I am fairly sure that down to the smallest districts across the US, people have the data. What we’ve not seeing happening it seems is a collation, a collection of that data at state and national level with the speed which one might hope to see from the perspective of global health research.”
