HealthDay Reports: There May Be 6 Types of COVID-19

Using a mix of symptoms, body weight and other factors, the researchers developed a model that predicts which patients will need to be hospitalized and need breathing support.

There May Be 6 Types of COVID-19

TUESDAY, July 28, 2020 (HealthDay News) -- COVID-19 may not be just one disease, but six distinct types, a new British study claims.

Each type differs in severity and in the need for respiratory support during hospitalization, the researchers added.

Cough, fever and loss of smell are the usual symptoms of COVID-19, but the range of symptoms can include headaches, muscle pain, fatigue, diarrhea, confusion, loss of appetite, shortness of breath and more.

HealthDay Reports: More Layers Are Better With Homemade Face Masks

A video recording showed that the 3-ply surgical mask was the most effective, but even a single-layer mask reduced the spread of droplets.

More Layers Are Better With Homemade Face Masks

FRIDAY, July 24, 2020 (HealthDay News) -- When it comes to homemade face masks, two or three layers of fabric is best, researchers say.

That's what you need to keep droplets from your nose and mouth from spreading the virus, the Australian scientists found.

Several kinds of material have been suggested for making masks, but there's little or no evidence of how effective they are, the team noted.

HealthDay Reports: How Immune System Fights COVID-19 May Be Key to Vaccine Success

In a small study, all 10 patients who had severe COVID-19 symptoms produced T-cells that worked with antibodies to try to kill the virus and stop the infection.

How Immune System Fights COVID-19 May Be Key to Vaccine Success

MONDAY, July 6, 2020 (HealthDay News) -- Even the sickest COVID-19 patients make T-cells to fight the infection, a new study finds.

This means that a COVID-19 vaccine will have to cause the body to make T-cells along with antibodies, researchers say.

The immune response to the SARS-CoV-2 virus, which causes COVID-19, was the same in American and Dutch patients in the study.

HealthDay Reports: COVID-19 Blood Test Might Predict Who Will Need a Ventilator

Researchers found that blood levels of a certain cytokine are predictive of the course of COVID-19.

COVID-19 Blood Test Might Predict Who Will Need a Ventilator

WEDNESDAY, July 1, 2020 (HealthDay News) -- A blood test may predict which COVID-19 patients are likely to need a ventilator.

This finding could lead to a scoring system that would flag at-risk patients for closer monitoring and to personalized treatments. It may also help explain how diabetes makes outcomes worse, according to researchers from the University of Virginia School of Medicine.

The study focused on 57 COVID-19 patients who needed a ventilator to breathe. Researchers compared samples of their blood to that from patients who did not need a ventilator.

HealthDay Reports: COVID Spreads Quickly in Crowded Homes, Poor Neighborhoods

One of the researchers said the study shows that neighborhood socioeconomic status and household crowding are strongly associated with risk of infection.

COVID Spreads Quickly in Crowded Homes, Poor Neighborhoods

TUESDAY, June 23, 2020 (HealthDay News) -- Poverty and crowded living conditions increase the spread of the coronavirus that causes COVID-19, a new study suggests.

Researchers reached that conclusion after testing nearly 400 women who gave birth at two hospitals in New York City during the peak of the COVID-19 outbreak.

"Our study shows that neighborhood socioeconomic status and household crowding are strongly associated with risk of infection. This may explain why Black and Hispanic people living in these neighborhoods are disproportionately at risk for contracting the virus," researcher Dr. Alexander Melamed said in a Columbia University news release.

HealthDay Reports: COVID-19 Can Start With Neurological Symptoms

Researchers found that neurological symptoms can appear before the more commonly known symptoms of COVID-19 infection like fever and cough.

COVID-19 Can Start With Neurological Symptoms

MONDAY, June 15, 2020 (HealthDay News) -- While a fever and cough have seemed to be the early warning signs of COVID-19, new research shows almost half of hospitalized patients experience a host of neurological problems.

In fact, headaches, dizziness, strokes, weakness, decreased alertness or other neurological symptoms can appear before the more commonly known symptoms of infection with the new coronavirus (known as SARS-COV-2), the researchers said.

Those neurological symptoms can also include loss of smell and taste, seizures, muscle pain and difficulty concentrating.

HealthDay Reports: When COVID-19 Strikes in Pregnancy, C-Section Tied to Worse Outcomes

Risks associated with a C-section rise when the mother has COVID-19.

When COVID-19 Strikes in Pregnancy, C-Section Tied to Worse Outcomes

THURSDAY, June 11, 2020 (HealthDay News) -- Pregnant women with COVID-19 who deliver by cesarean section may be at greater risk for complications that affect them and their babies, new research suggests.

The study focused on 82 women with COVID-19 -- four of them with severe symptoms -- who gave birth in hospitals in Spain. Thirty-seven women delivered by cesarean section (C-section), including eight as a direct result of COVID-19 issues.

Nearly 30% of babies delivered by C-section had to go to the neonatal intensive care unit, compared with fewer than 20% of babies delivered vaginally, the researchers found.

HealthDay Reports: Lab Experiments Show How Masks Could Protect Against COVID-19

The investigators found that the virus tends to first infect the nasal cavity, which is why face masks might help limit transmission of the virus.

Lab Experiments Show How Masks Could Protect Against COVID-19

TUESDAY, June 9, 2020 (HealthDay News) -- Scientists studying the SARS-CoV-2 coronavirus -- which causes COVID-19 -- believe they've discovered why face masks might help limit transmission of the virus.

The virus tends to first infect the nasal cavity, replicating less well in the lower respiratory tract, University of North Carolina (UNC) researchers found. However, sometimes it's sucked into the lungs, where it can cause serious consequences, including fatal pneumonia.

"If the nose is the dominant initial site from which lung infections are seeded, then the widespread use of masks to protect the nasal passages, as well as any therapeutic strategies that reduce virus in the nose, such as nasal irrigation or antiviral nasal sprays, could be beneficial," study co-author Dr. Richard Boucher said in a university news release.
