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."

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.

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.

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.

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.

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.

University of Arizona Heath Sciences researchers developed one of the most accurate COVID-19 antibody tests available and now have shown antibodies persist for months after infection, providing long-term immunity.

The question of how long immunity lasts against COVID-19 is one step closer to being answered, according to a new study. Researchers from the University of Arizona Health Sciences studied the production of antibodies from a sample of nearly 6,000 people and found immunity lasts for at least several months after being infected with SARS-CoV-2, the virus that causes COVID-19.

Three new reports show coronavirus immunity can last for months -- and maybe even longer. The findings suggest that many, if not most, people who recover from coronavirus infections are protected for at least a period of time. One study found that people produce antibodies that protect against infection and last for at least five to seven months. "We have one person that is seven months out. We have a handful of people that are five to seven months out," Deepta Bhattacharya, an immunobiologist at the University of Arizona College of Medicine, told CNN.

After a dismal year for the airline industry because of the coronavirus pandemic, some carriers are emphasizing enhanced health and safety measures in a bid to lure back travelers in time for the holidays. "You're in a contained tube for a number of hours. So I think people who are higher-risk for whatever reason need to be wary about whether the travel is essential or not," said Dr. Shad Marvasti with the University of Arizona College of Medicine.
