Another study suggests common cold protects some from COVID-19

October 5, 2020

The common cold can make you miserable, but it might also help protect you against COVID-19, a new study suggests.

The researchers added that people who’ve had COVID-19 may be immune to it for a long time, possibly even the rest of their lives.

The research focused on memory B cells, long-lasting immune cells that detect pathogens, produce antibodies to destroy them, and remember them for the future.

The study authors compared blood samples from 26 people who were recovering from mild to moderate COVID-19 and 21 healthy people whose samples were collected six to 10 years ago, long before they could have been exposed to COVID-19.

They found that B cells that attacked previous cold-causing coronaviruses appeared to also recognize the coronavirus that causes COVID-19.

This could mean that anyone who’s ever been infected by a common cold coronavirus — nearly everyone — may have some amount of immunity

(Reuters) – Nine U.S. states have reported record increases in COVID-19 cases over the last seven days, mostly in the upper Midwest and West where chilly weather is forcing more activities indoors.

On Saturday alone, four states – Kentucky, Minnesota, Montana and Wisconsin – saw record increases in new cases and nationally nearly 49,000 new infections were reported, the highest for a Saturday in seven weeks, according to a Reuters analysis. Kansas, Nebraska, New Hampshire, South Dakota and Wyoming also set new records for cases last week.

Daytime highs in many of these states are now in the 50s Fahrenheit (10 Celsius). Health experts have long warned that colder temperatures driving people inside could promote the spread of the virus.

Montana has reported record numbers of new cases for three out of the last four days and also has a record number of COVID-19 patients in its

But health experts cautioned that there’s no guarantee the numbers will continue to fall, as chillier October weather begins to usher outdoor activities indoors.

Taison Bell, an assistant professor of medicine specializing in infectious diseases and critical care at the University of Virginia in Charlottesville, said the greater Washington region is “in a bit of a steady state” in its number of reported coronavirus cases. The region’s caseload had held steady for several weeks before starting to tick downward about 10 days ago.

He also cautioned that the arrival of cooler weather could increase the spread of the virus as people increasingly decide to congregate indoors.

Neil J. Sehgal, an assistant professor of health policy and management at the University of Maryland School of Public Health, urged residents to consider the pandemic as they make plans for the holidays. They should remember that this is “not the normal holiday season,”

Additives found in cold cuts, ice cream, bread, other processed food cause concern

According to the Food and Drug Administration, there are more than 3,000 additives used in foods to — among other things — enhance flavor, texture or shelf life. They range from simple ingredients such as sugar or salt to chemical compounds with unpronounceable names.

You certainly don’t need to avoid them all, but even among additives that the FDA has deemed safe, there is some evidence that not all are completely benign. We’ve taken a look at the latest research on some food additives that have recently sparked some controversy or concern.

Nitrates and nitrites

These food additives are used mainly as preservatives in processed meats — such as bacon, hot dogs and deli meats.

What’s the concern? When these foods are cooked at high heat, or when they mix with stomach acid during digestion, the added nitrites can generate nitrosamines. Nitrosamines may be carcinogenic, and some research shows that
