Getting COVID Again Is More Dangerous Than People Realize
Doctors share why it’s still important to take the COVID virus seriously, including the dangerous health effects of getting re-infected.
The New Paradigm of Airborne Disease
The COVID-19 pandemic shattered established views of airborne disease. Although it represents a paradigm shift in public health, the field has yet to catch up.
Identifying subtypes of Long COVID: a systematic review
This review identified four major approaches for categorizing Long COVID patients
and their symptoms. Symptom co-occurrence and organ system were the most commonly
used subtypes used in categorization. Fatigue and olfactory–gustatory dysfunction
emerged as recurrent core symptoms across multiple subtypes of Long COVID.
Vascular and inflammatory diseases after COVID-19 infection and vaccination in children and young people in England: a retrospective, population-based cohort study using linked electronic health records
Children and young people have higher risks of rare vascular and inflammatory diseases
up to 12 months after a first COVID-19 diagnosis and higher risk of rare myocarditis
or pericarditis up to 4 weeks after a first BNT162b2 vaccine, although the risk following
vaccination is substantially lower than the risk following infection. These findings
are of great importance for national policy makers and caregivers considering vaccination
consent for children, and support the public health strategy of COVID-19 vaccination
in children and young people to mitigate the more frequent and persistent risks associated
with SARS-CoV-2 infection.

COVID-19 Safety: How To Stay Safe, Keep Each Other Safe, and Move as Leaders and Good Relatives in Collective Care Efforts | NIWRC
While many leaders and institutions have pushed “post-pandemic” rhetoric, virologists, epidemiologists, and other science/health experts continue to help us understand the reality that COVID-19 never went away.
“SARS-CoV-2 airborne detection within different departments of a COVID-19 hospital building and evaluation of air cleaners in air viral load reduction”
Study suggests that air cleaners can reduce up to 98.1 % of viral load in the air of a Covid patient's room with confirmed positive airborne viral RNA. Rooms with HEPA ventilation had zero virus detected.
Global prevalence of long COVID and its most common symptoms among healthcare workers: a systematic review and meta-analysis
This meta-analysis investigates the prevalence and common symptoms of long COVID among healthcare workers (HCWs) globally. It found that 40% of HCWs who had COVID-19 experienced long COVID, with the most common symptoms being fatigue, neurological issues, loss of smell/taste, muscle pain, and shortness of breath. While the prevalence seems similar to the general population, the study notes limitations due to inconsistent definitions and data quality, emphasizing the need for standardized research methods and highlighting the substantial burden of long COVID on the healthcare workforce.
New research links long COVID to worse health-related quality of life | CIDRAP
Researchers analyzed 2022 data from the Behavioural Risk Factor Surveillance System surveys completed by 108,237 COVID-19 survivors who did or didn't have persistent symptoms. Participants' health-related quality of life (HRQL) was assessed via SRGH, self-reported mental and physical health, and efficiency in completing activities of daily life.
Of all participants, 35% were aged 18 to 34 years, 46.5% were men, and 22.7% had long COVID, also known as post-COVID condition (PCC), defined as having lingering symptoms at least 3 months post-infection.
The risk of Long Covid symptoms: a systematic review and meta-analysis of controlled studies
Estimating the risk of long COVID is challenging because many of its symptoms are associated with other conditions. Here, the authors conduct a systematic review and meta-analysis of studies that estimate long COVID risk while accounting for background symptoms using comparator control populations.

Identifying people with post-COVID condition using linked, population-based administrative health data from Manitoba, Canada: prevalence and predictors in a cohort of COVID-positive individuals
A new Manitoba-specific study using whole-population health data looked at 66,365 Manitobans with positive Covid tests (PCR) between 2020-21 and found that 23.3% had Long Covid.
Children face elevated health risks for years after covid
Researchers found that those with SARS-CoV-2 infections had a 63% increased risk of developing one or more cardiovascular conditions—including arrhythmias, heart inflammation, chest pain, palpitations, and hypertension—compared to those with negative tests and no documented history of SARS-CoV-2 infection. These risks were elevated regardless of whether the patient had a congenital heart defect (CHD).
Young patients with positive SARS-CoV-2 tests had a 17 percent higher risk of developing chronic kidney disease tested at stage 2 or higher, indicating mild kidney damage that still functioned well, and 35 percent higher risk of chronic kidney disease at stage 3 or higher, meaning there is mild to severe damage impacting kidney function, from one month to two years after infection.
Patients who had a positive SARS-CoV-2 test—compared to those with a negative test—had a 25 percent increased risk of developing at least one gastrointestinal symptom or disorder in the post-acute phase, and a 28 percent increased risk in the “chronic phase” from six months to two years after the SARS-CoV-2 test.
Global Prevalence of Long COVID, its Subtypes and Risk factors: An Updated Systematic Review and Meta-Analysis
Meta-analysis of 429 studies published from 2021-2024 estimated a pooled global long COVID prevalence of 36% in COVID-19 positive individuals.
Global prevalence of post-COVID-19 condition: a systematic review and meta-analysis of prospective evidence, HPCDP: Vol 45(3), March 2025 - Canada.ca
More than 50% of COVID-19 survivors experienced at least one PCC symptom up to 2 years after their initial infection.
Studies across 14 nations show 25% to 30% rate of long COVID
Among the 25.1% of participants who said they experienced long-COVID symptoms, 12.8% reported sleeping disorders.
Long COVID facts and findings: a large-scale online survey in 74,075 Chinese participants
An analysis of over 68,000 valid responses found that common long COVID symptoms include fatigue, memory decline, reduced exercise ability, and brain fog, with lower rates among individuals infected only once. Women were more prone to long COVID, and symptoms varied by age, except for sleep issues and muscle or joint pain, which were more frequent in older adults. Northern China showed higher prevalence, possibly due to colder temperatures. Risk factors included pre-existing conditions, alcohol use, smoking, and severe acute infection. While reinfection generally caused milder acute symptoms, it increased the likelihood and severity of long COVID. Vaccination, especially with multiple boosters, significantly reduced long-term symptoms. Additionally, COVID-19 patients reported more bacterial, flu, and mycoplasma infections, and 8–10% believed they developed chronic diseases due to the virus.
The risk of Long COVID, explained
The question has been asked over and over again: what is the risk of Long COVID and how does that risk increase with each infection? Let's break down the science and get to know this invader that is making a host out of us.

Long COVID Showed Me the Bottom of American Health Care
"The closure of long-COVID clinics in recent years has affected patients who need care. I talked with people who, like me, have been living with long COVID later in the pandemic. Ryan Parker lives in Portland, Oregon; is a member of the Northern Cheyenne tribe; and used to work in philanthropy. Like many people with long COVID, Parker tried to work through his illness. He told me he returned from one work trip so sick that he couldn’t get out of bed for a month. Last fall, the long-COVID clinic that was treating him closed. Because of the disease, Maeve Sherry has been disabled and unable to work for three years. They found a long-COVID clinic in Great Falls, Montana, three hours from where they lived at the time, but it closed in December of 2023, they said. There are now no long-COVID clinics in Montana. When Myisha Hill was still struggling to do household chores, take care of her kids, and even talk weeks after a COVID infection, she looked up the long-COVID clinic near where she lives in Las Vegas, she told me. But it, too, had closed. There are now no long-COVID clinics in Nevada."
