Most common symptoms of COVID have changed, study says. That’s what they are

The study found that the most commonly reported symptoms of COVID-19 in recent weeks have changed since the coronavirus began spreading around the world.

According to the Zoe Health Study, an ongoing research project in the UK that tracks the virus through the COVID Symptoms Tracker program, core symptoms were largely similar regardless of vaccination status. Participants self-report their COVID-19 experiences using the app.

The latest study list, published on October 20, highlights how “previously recorded symptoms change with the development of virus variants,” the report said.

According to the study, four of the five main symptoms of COVID-19 were the same in participants who received two doses of the vaccine, one dose of the vaccine, and those who were not vaccinated. Such symptoms were headache, constant cough, sore throat and runny nose.

Heart attack deaths have risen sharply among young adults in the US in the second year of the COVID pandemic

According to new research from scientists at Cedars-Sinai Medical Center in Los Angeles, as the number of COVID-19 infections increased during the pandemic, so did the number of deaths from heart attacks, with the largest increase among adults aged 25-44.

“The dramatic increase in heart attacks during the pandemic reversed what had been a decade of steady improvement in cardiac death,” said Dr. Yi Hui Yeo, first author of the study and a physician scientist at Cedars-Sinai. “We are still learning the many ways in which COVID-19 affects the body, regardless of age, gender, ethnicity or race.”

Scientists around the country and the world continue to publish results showing that SARS-CoV-2 infections increase the risk of other serious diseases, such as stroke, nerve damage and some autoimmune diseases.

Has the COVID pandemic helped the climate? Here’s an overview of California’s carbon emissions in 2020

The COVID-19 pandemic has had one positive outcome for California: It has helped reduce the state’s carbon footprint, at least temporarily.

Carbon dioxide emissions fell 9% in 2020, the California Air Resources Board said Wednesday, the biggest drop in a year since California began measuring man-made carbon emissions.

But aviation board officials acknowledged that the results were skewed by Gov. Gavin Newsom’s stay-at-home orders in the early months of the pandemic, when offices, malls and freeways were largely empty and the economy ground to a halt.

Stephen Cliffe, the board’s chief executive, called the 2020 results “outliers” and said greenhouse gas emissions had certainly increased over the past two years as economic activity improved.
