Long-haul COVID: What doctors want patients to know

The rise of telemedicine: A post-pandemic analysis

Before COVID-19, telemedicine remained on healthcare's periphery; however, the pandemic thrust it into the limelight, transforming how we approach medical care. This comprehensive review published by Press Ganey dives deep into the evolution,...

COVID accelerated antibiotic resistance

The COVID-19 pandemic was caused by a virus, and viruses can’t be treated with antibiotics. But recent research finds that COVID patients were given a tremendous amount of antibiotics, contributing to the problem of antibiotic-resistant bacteria. Why? This NPR feature sheds light on an unexpected side effect of the pandemic.

Why dizziness is still a mystery

Dizzy spells can completely upend the lives of those suddenly struggling to find their footing. Despite this severe impact, the different flavors of dizziness and their sources continue to elude medical understanding. This article follows a health...

Loss of sense of smell is a common symptom of COVID-19 infection

In 2020, researchers discovered why this occurs. The virus that causes this infection attacks the cells that support smell-detecting neurons. Once infection clears, the sense of smell typically returns, though the exact timeline for that differs by patient. (Some users may experience a paywall.)

Watch an expert's take on the rare disease hantavirus—and why it's not of great concern to the general population

This rare zoonotic disease, transmitted to humans primarily through infected rodent droppings, urine, or saliva, is rarely spread between people. The disease was of particular concern in spring 2026, when an outbreak occurred on a 150-person cruise ship, prompting a flurry of action, including contact tracing for passengers in their home countries. The disease can be fatal. But early care—primarily oxygen support—can help patients survive.

Read the Surgeon General's 2023 loneliness report claiming loneliness is an epidemic

This report details the specific health threats linked with loneliness, including that loneliness and social isolation can increase the risk of premature death by nearly 30%. Loneliness lowers our capability to mount an effective immune response to viruses and respiratory illness, can cause chronic inflammation on par with physical inactivity, and increases the risks for anxiety, depression, dementia, heart disease and stroke.

Long-term memory issues among West Nile survivors may be from immune response, not virus

Rodent research suggests that long-term neurological complications such as fatigue, weakness, difficulty walking, and memory loss, may be due to the immune system systematically destroying parts of neurons in the brain in response to the infection, rather than due to viral infection itself.

Chronic lyme isn't a medically recognized diagnosis in conventional medicine

It describes a constellation of symptoms attributed to a persistent Lyme infection—meaning the bacteria have remained present even after antibiotics. It often occurs among people who have never received a positive test for Lyme. Doctors do recognize "post-treatment Lyme disease syndrome," however, which can include muscle and joint pain, fatigue, and cognitive difficulties after treatment for confirmed Lyme.

Lengthy incubation periods are why it’s tough to link foodborne illness to specific foods

People may not get sick from a foodborne pathogen for several days after consuming it, making it a challenge to link the illness and its cause. Factors influencing when a person starts feeling sick—even as the pathogen is multiplying in the gut—include individual variations in immune systems and gut microbiomes, what other foods are in the person’s body, and how much of the pathogen was consumed.

Human-to-human transmission of hantavirus remains extremely rare, so the 2026 hantavirus cruise ship outbreak doesn't mean we're facing a COVID-style pandemic risk.

Patients are a part of the progress

Why we don't have an answer for the common cold

Since a landmark study of the common cold in 1925, researchers have learned much more about the seasonal ailment. Despite continuous study, people still contract colds for similar periods of time at the same rate with the same symptoms, and there's no vaccine. This article explains how the many viral strains make it hard to control.

Links between long-term caregiving and chronic stress

This Cleveland Clinic overview suggests that around 60% of people caring for family or loved ones with health conditions will experience burnout. Caregivers prepare meals, help with transportation, administer medications, and perform daily tasks for others, all while managing their own lives. This guide may help readers overcome the guilt or frustration of long-term caregiving to seek alternative options.

David Fajgenbaum had a few months to live after a diagnosis with a rare form of Castleman's disease. By studying his blood, medical records, and broader literature, he was able to identify the cause of his condition and a treatment. He's been in total relapse for ten years.

The lack of diversity in clinical trials is undermining the future of precision medicine

Medicine works better when the treatments are tailored to fit each individual person’s biology and history. Homogeneous patient selection in clinical trials means treatments and care are being refined based on only a small range of variables, some of which may not apply to you. This 40-minute podcast episode discusses the historical and current reasons for the lack of clinical trial diversity and what this means for the future of personalized medicine.

Brain death is a uniquely modern problem stemming from modern ventilators

Patients who would have once died from devastating brain injury can now live on a ventilator for a long period of time, creating ethical, medical, and legal dilemmas.

'Tomato flu' outbreak in India turned out to be HFMD

An illness initially dubbed "tomato flu" in 2022 that sickened children in Kerala, India, with symptoms typical of hand, foot, and mouth disease turned out to be that—not a new ailment. A letter published in the prestigious journal The Lancet had initially described the illness as "a new virus" but at least some of the children ultimately tested positive for one of the viruses that causes HFMD, so it wasn't a new condition after all. (Some users may encounter a paywall.)

MS disproportionately sickens women, but men tend to have worse outcomes

Though the disease is more common in women, men's symptoms progress more quickly, with men more often diagnosed with progressive MS and men's cases typically resulting in more severe symptoms—perhaps due at least partly to more delayed diagnosis—and more severe disability over time.
