The cold and flu season of 2022 has begun with a vengeance. Viruses that have been unusually scarce over the past three years are reappearing at remarkably high levels, sparking a “tripledemic” of COVID-19, the flu and respiratory syncytial virus, or RSV. This November’s national hospitalization levels for influenza were the highest in 10 years.

As the days get shorter and the weather colder in the northern hemisphere, health officials have warned of a perfect storm of infectious respiratory diseases over the winter months.
Outbreaks of seasonal diseases like influenza and respiratory syncytial virus (RSV) are already putting pressure on the overburdened NHS. If surges of these illnesses collide with another large COVID wave, we could be facing a public health disaster. Some have called this threat a “tripledemic”.

Today, the U.S. Food and Drug Administration proposed updated criteria for when foods can be labeled with the nutrient content claim “healthy” on their packaging. This proposed rule would align the definition of the “healthy” claim with current nutrition science, the updated Nutrition Facts label and the current Dietary Guidelines for Americans.
