Covid-19 has claimed a million lives already; real toll may be way higher

The world officially recorded 1 million deaths from Covid-19 in one of the most sobering milestones of the pandemic, but the real tally might be almost double that.Actual fatalities from the worst outbreak in a century may be closer to 1.8 million — a toll that could grow to as high as 3 million by the end of the year, according to Alan Lopez, a laureate professor and director of the University of Melbourne’s global burden of disease group. The coronavirus’s rapid spread and ability to transmit in people who show no signs of the disease have enabled it to outrun measures to accurately quantify cases through widespread diagnostic testing.

Even in countries with sophisticated health systems, mortality is difficult to accurately gauge. Tens of thousands of probable Covid-19 deaths in the U.S. weren’t captured by official statistics between March and May, a study in July found, frustrating efforts to track and mitigate the pandemic’s progression.The dearth of accurate data undermines the ability of governments to implement timely strategies and policies to protect public health and promote economic recovery. If the mortality from Covid-19 reaches 3 million as Lopez predicted, it would rank the disease among the world’s worst killers. An undercount in deaths could also give some people a false sense of security, and may allow governments to downplay the virus and overlook the pandemic’s burden.No SystemIndia has confirmed more than 6 million Covid-19 cases, but accounts for only about 95,000 of the 1 million reported deaths worldwide, according to data collected by Johns Hopkins University. The country, which has the highest number of infections after the U.S., lacks a reliable national vital statistics registration system to track deaths in real time. Meanwhile, in Indiana in the U.S. researchers found that although nursing home residents weren’t routinely tested for the virus, they represented 55% of the state’s Covid-19 deaths.“Yes, cases are reported daily everywhere, but as soon as you get to the next tier down, like how many were admitted to hospitals, there have just been huge gaps in the data,” said Christopher J. Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington in Seattle. Medical data, including duration of illness and symptoms, help to ascribe a probable cause of death, he said.Patients with heart disease, diabetes, cancer and other chronic conditions are at greater risk of dying from Covid-19. Some governments, including Russia, are attributing the cause of deaths in some of these patients to the pre-existing condition, raising questions about the veracity of official mortality data.WHO GuidelinesIn July, Russia recorded 5,922 fatalities due to Covid-19. At least 4,157 other deaths were linked to the coronavirus, but not included in the tally because of how the nation defines such deaths. Overall, it recorded 29,925 more deaths in July than in the same month of 2019.The WHO laid out guidance for classifying coronavirus deaths in June, advising countries to count fatalities if patients had symptoms of the disease regardless of whether they were a confirmed case, and unless there was a clear alternative cause. A Covid-19 fatality should be counted as such even if pre-existing conditions exacerbated the disease, said the organization. The U.S. Centers for Disease Control and Prevention released similar guidelines.Still, it may take health workers certifying deaths time to adopt the methodology, the University of Melbourne’s Lopez said. His research has received funding by Bloomberg Philanthropies, set up by Michael Bloomberg, founder and majority owner of Bloomberg News’ parent Bloomberg LP.“Doctors often are learning as they go along, so they’re not certifying all the deaths that are due to Covid as Covid deaths,” Lopez said.Japan DropAlthough the pandemic has altered mortality patterns worldwide, not all of the changes are a direct result of the pandemic, he said. Physical distancing measures may have reduced road fatalities and deaths caused by influenza. In Japan, which has been scrutinized for its lack of widespread testing and relatively lax containment efforts, deaths fell by 3.5% in May from a year earlier even as Covid-19 cases peaked.“The pandemic actually works in contradictory ways to affect mortality,” Lopez said.Likewise, the economic cost of the pandemic — which may top $35.3 trillion through 2025 — will be driven more by changes in people’s spending patterns than number of deaths and government-mandated “lockdown” measures, according to Warwick McKibbin, a professor of economics at the Australian National University and a non-resident senior fellow at the Brookings Institution in Washington.“We estimate this outbreak is going to cost tens of trillions to the world economy,” McKibbin said in an interview. “The change in economic outcomes is caused by individuals changing their behavior, not because the government mandated a shutdown.”Worldwide, the growth in the number of daily deaths has eased since spiking in March and April, helped by improved medical care and ways to treat the disease. But as resurgences flare in Europe and North America ahead of winter and the flu season, Covid-19 fatalities may rise sharply again. It took nine days for cases in the U.K. to double to 3,050 in mid September, compared with the previous doubling time of five weeks, the BMJ journal said last week.

Covid-19 patients between ages 75 to 84 are 220 times more likely to die from the disease than 18-to-29-year-olds, according to the CDC. Seniors over 85 years have a 630 times higher risk of dying. The older age of fatal Covid-19 cases has made some people think “they’re old people, they’re going to die anyway,” said Michael Osterholm, an epidemiologist and director of the Center for Infectious Disease Research and Policy at the University of Minnesota.“I have a really hard time with that,” Osterholm said in an interview. “That’s an unfortunate and very sad way to come to understand this pandemic. Many of those people who died are very important loved ones to so many of us that it’s hard to just dismiss it as it’s just a number.”
