COVID-19 is primarily a respiratory disease. But it presents odd neurological symptoms like cognitive dysfunction and the loss of taste and smell. Researchers looking at the brains of those worst hit saw a big clue to why: brain areas that appeared stroke damaged.

As more information has become available, scientists realize Covid is a multi-system disease that can potentially affect any organ. And the impact of that can linger for weeks and months. Here’s what you should know about the long haul symptoms…

As the COVID-19 vaccines become available, there are questions about its safety, especially for people with certain allergies. After all there are people who can’t take the flu vaccine. So, allergy experts are taking a close look at this issue and, along with the CDC, have information that can help you know what to expect. […]

We’ve long known vitamin D supports a healthy immune system. Now it’s apparent it provides significant defense against SARS-Cov-2, the virus behind COVID-19.

Since the pandemic began, we’ve been asking questions: Who will it strike? Why do some people suffer a severe case or loss of life? And most urgently, how can we stay healthy?

After all we’ve been through, reach around and pat yourself on the back. You deserve it. You’re a survivor and that means you’re looking ahead… Because the mutant variants of COVID will keep coming. If you haven’t made it a priority to ramp up your immune system, there’s still time…

A weird and common symptom of COVID-19 affecting up to 80 percent of us is the loss of smell. Some suffer parosmia, where their sense of smell is distorted, making lemons smell like cabbage. Luckily, it’s possible to “train” your sense of smell back to normal…

Since the beginning of the pandemic, we’ve been told to use alcohol-based hand sanitizers. But shelves that once were full of the germ-killing goo have gone bare. That’s ok, because research is finally catching up with what works and what doesn’t against the virus. And that applies not just to treatment but hand sanitizer too. […]

As COVID-19 spreads, scientists are unraveling the complexities of the disease and the virus behind it. One thing they’ve discovered is a particular mechanism that could explain why there are those among us, like the elderly and people with chronic disease, who are more vulnerable to infection, as well as provide clues to help them. […]

You know the mantra for how to avoid getting sick this winter: Wash your hands and wear a mask. And when the days start getting shorter, the temperature drops and cold and flu season kicks in, we could all use an immunity boost, COVID or no COVID. That’s where my favorite secret weapon comes in… Yes, […]

Sleep apnea is a progressive condition that causes a person to stop breathing during sleep, often multiple times a night. It’s linked to hypertension, stroke and heart failure.

The COVID-19 pandemic continues to spread across the US.
