People who survived COVID-19 early in the pandemic, before there were vaccines, continued to be at higher risk for a slew of health problems for up to two years after they got over their initial infections, a new study finds, and that was especially true if they were hospitalized.
These health problems include heart problems, blood clots, diabetes, neurologic complications, fatigue and difficulties with mental health and have come to be known collectively as long COVID.
When researchers tallied the risks for more than 80 different complications that are associated with long COVID, they translated the collective toll into a metric called a disability adjusted life year, or DALY. Each DALY represents one year of healthy life lost to illness. They found that long COVID generated more than 80 disability-adjusted life years, or DALYs, for every 1,000 people who weren’t hospitalized for their initial infection.
That means long COVID creates a higher burden of disability than either heart disease or cancer, which cause about 52 and 50 DALYs for every 1,000 Americans, respectively, according to the Institute for Health Metrics and Evaluation’s Global Burden of Disease study.
“When I looked at that initially, I was really shocked,” said study author Dr. Ziyad Al-Aly, who is director of the clinical epidemiology center at the Veterans Affairs St. Louis Health Care System. “That’s actually a huge number.
“We did the analyses multiple times and, and then it just always can come back to be to be the same.”
After considering their findings, though, Al-Aly said it really shouldn’t be such a huge surprise that long COVID is so disabling, because it affects so many different parts of the body.
Al-Aly said his study should be a wake-up call.
“I think that we need to understand that infections lead to chronic disease and we need to take infection seriously,” even when it seems to be mild, Al-Aly said.
The study, which was published Monday in the journal Nature Medicine, looked at the medical records of nearly 140,000 veterans who survived for 30 days after getting a COVID-19 infection in 2020, and compared their health outcomes to nearly 6 million other patients in the VA health system who had no evidence of infection.
The study has some important caveats. On average, the people in the study were older, in their 60s, and almost 90% were male, so the findings may not translate to those who are younger or to women.
None of the people in the study were vaccinated at the time they were infected because the vaccines had not been developed yet, and there weren’t yet antiviral treatments targeted to COVID-19. Studies have since shown that vaccination and early treatment can help curb long COVID risk.
The researchers only included people in the COVID-19 infection group if they had a positive test, but tests were slow to roll out early in the pandemic, and the researchers say many people may have had the infection with no test results recorded in their medical records. That may have resulted in some people being included in the control group when they should have been in the infection group. If that was a large number of people, the study authors say, their results may be an underestimation of the true risks people faced post-infection.
Al-Aly said he used this group because he wanted to learn more about the long-term outcomes for people who get COVID-19, and he needed to find patients who were more than two years past their infections, so these risks may have gone down over time as vaccines and better treatments were developed.
Still, the study paints a sobering picture of how long people faced physical consequences from early infections.
The study found people who were not hospitalized with COVID-19, still had an elevated risk of death for about six months after they first got sick.
Over the two years, their risk of having many long COVID symptoms went down, but it remained elevated for about one-third of the 77 ailments that were studied. Some of those lingering problems included blood clots, a slower than normal heartbeat, fatigue, diabetes, gastrointestinal problems, sleep problems, muscle and joint pain, headache, hearing and smell loss, and autonomic nervous system dysfunction.
People in the group who had to be treated in the hospital for an initial COVID-19 infection fared even worse. They remained at increased risk for death and hospitalization for at least two years after they recovered from their acute symptoms.
Out of 77 different long COVID issues studied, people who were hospitalized remained at elevated risk for about two-thirds of them even two years later. These included heart problems, stomach problems, memory and thinking difficulties, blood clots, diabetes and lung problems. They were also more likely to have a substance use disorder, including for alcohol and opioids. They were also more likely to report contemplating suicide.
“Our findings highlight the substantial cumulative burden of health loss due to long COVID, and emphasize the ongoing need for health care for those faced with long COVID,” said Al-Aly.
“It appears that the effects of long COVID for many will not only impact such patients and their quality of life, but potentially will contribute to a decline in life expectancy, and also may impact labor participation, economic productivity, and societal well-being.”
HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.
The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.
Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.
“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”
The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.
A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.
Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.
“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.
Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.
The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.
“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.
Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.
Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.
Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.
The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.
“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.
Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.
Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.
Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.
A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
