Public health experts are warning of a ‘quad-demic’ this winter. Here’s where flu, COVID, RSV, and norovirus are spreading
With COVID-19, a person may experience symptoms anywhere from two to five days, and up to 14 days after infection. Those with the flu are potentially contagious for about one day before they start ...
For this winter’s COVID-19 surge, Justman says that hospitalizations are expected to peak at a rate higher than during this past summer’s surge but probably lower than during last winter's peak.
With sufficient humidity in the cooler layer, fog is typically present below the inversion cap. An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky.
There are three stages, according to the way COVID-19 infection can be tackled by pharmacological agents, in which the disease can be classified. [71] Stage I is the early infection phase during which the domination of upper respiratory tract symptoms is present.
Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface.

Basically, there’s a ton of norovirus floating around out there. Norovirus is no joke—it can cause vomiting and diarrhea (often at the same time), making for a miserable experience.
Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.
