Fry's grocery stores is no longer sanitizing shopping carts for customers. Instead, the stores are providing sanitizing wipes for customers to do it themselves. "Obviously shopping carts are one of those things that a high number of people are going to be touching," Dr. Sahd Marvasti from the University of Arizona College of Medicine said. "But if I had to choose between whether or not masks were required versus universal sanitizing, I would choose masks."

Milk drinking in America has fallen by 40% since 1975. But its production and consumption has risen by 9%. The article references a study published in Nutritional Reviews in February 2020 by Elizabeth Jacobs, PhD, and colleagues from the University of Arizona College of Public Health in Tucson. The researchers recommend milk be downgraded as a separate and essential food. Dr. Jacobs says it should be placed in a much lower category as one of many foods that could provide protein.

The number of new weekly COVID-19 cases in Arizona recently rose to its highest point since the first week in August. "What's happening here in Arizona, it's more like a slow boil," said Joe Gerald, an associate professor with the University of Arizona's Mel and Enid Zuckerman College of Public Health. "It's not like what we're seeing in other parts of the country, like North Dakota, South Dakota, Wisconsin. Those states look like Arizona did in June, where there's this rapid uptick."

A Canadian researcher has found that the virus that causes COVID-19 can hijack a pain receptor on our cells, using it to get into the cell, but also blocking its ability to signal pain. Interview with Rajesh Khanna, a professor of pharmacology at the University of Arizona College of Pharmacy.

Several new reports published recently show Covid-19 immunity can last for months. Researchers from the University of Arizona Health Sciences found antibodies that protect against infection can last for at least five to seven months after a Covid-19 infection. Interview with Deepta Bhattacharya, an immunobiologist at the University of Arizona College of Medicine.

Immunity against Covid-19 may persist for at least five months after being infected with the SARS-CoV-2 virus, according to a study led by an Indian-origin researcher in the US. We clearly see high-quality antibodies still being produced five to seven months after infection,” said Deepta Bhattacharya, associate professor at the University of Arizona College of Medicine in Tucson.

Chlorine disinfection is used by the majority of drinking water treatment municipalities to control microbial pathogens. Kelly Reynolds, professor and environmental microbiologist at the University of Arizona College of Public Health and Director of the Environment, Exposure Science and Risk Assessment Center, writes about emerging microbes that exhibit chlorine resistance.

With many kids in our area starting hybrid learning, parents have more questions about how COVID-19 affects children. While coronavirus is commonly known as a lung issue, the American Heart Association said it can involve the heart as well. In fact, Dr. Nancy Sweitzer, director of the Sarver Heart Center at the University of Arizona, is currently focusing on myocarditis in children, which can cause severe chest pain and inflammation of the heart.

The question of how long immunity lasts against COVID-19 is one step closer to being answered, according to a new study by researchers from the University of Arizona Health Sciences. Deepta Bhattacharya, associate professor and immunologist at the University of Arizona College of Medicine in Tucson is interviewed.

Should you or your guests fly? Should you take that likely much-needed vacation or push it to the equally uncertain future? Is air travel really that risky? To find out, The Show spoke with Paloma Beamer, associate professor in the College of Public Health at the University of Arizona. She’s an exposure scientist, who studies how people are exposed to disease — and designs ways for people to avoid it.
