Early in the pandemic, many researchers feared people who contracted COVID could be reinfected very quickly. This was because several early studies showed antibodies seemed to wane after the first few months post-infection.

It was also partly because normal human coronaviruses, which are one cause of common colds and are cousins of SARS-CoV-2, do not generate long-lasting immunity, so we can get reinfected with them after 12 months.

Over recent weeks and months, we’ve heard of several COVID cases in which people have tested positive after previously clearing the virus.

Scientists are hopeful being infected with COVID-19 confers immunity for a length of time. But some of these instances have raised concerns about reinfection. Although rare, it seems to be possible.

The other thing which could be at play in many of these cases is “prolonged viral shedding”.

Tab, the Coca-Cola company’s original diet soda brand, is headed to the soda graveyard, joining retired brands such as Like, Leed and Limette.

Coca-Cola has announced that it is discontinuing Tab after 57 years on the market, and fans of the drink will have until the end of December to purchase their last can of nostalgia.

From the beginning, Tab’s story has been one of perseverance. The brand survived initial low sales, the artificial sweetener scares of the 1960s and 1970s, lukewarm enthusiasm for the product at the corporate level and intermittent consumer availability to become – for a brief period – the most popular diet soda in America. Then, of course, Diet Coke came along.

Well-meaning advice for people freaking out about current events often includes encouragement to be patient, stay calm and keep the faith… but how on Earth are you supposed to do that amid the insanity of 2020?

As a practicing clinical psychologist and professor who studies how to manage anxiety and tolerate uncertainty, I offer 10 suggestions to make it through this highly stressful election period.

Two large recent studies show that people hospitalized for COVID-19 in March were more than three times as likely to die as people hospitalized for COVID–19 in August.

The first study used data from three hospitals in New York City. The chance of death for someone hospitalized for the coronavirus in those hospitals dropped from an adjusted 25.6% in March to 7.6% in August. The second study, which looked at survival rates in England, found a similar improvement.

The Centers for Disease Control and Prevention recently revised its guidance to acknowledge that COVID-19 can be spread through tiny airborne particles, known as aerosols. It had earlier removed a similar guidance from its website, saying it was “posted in error.”
