Bratwurst (German: [ËbÊaËtvÊÉÌ¯st] ( listen)) is a type of German sausage made from veal, pork or beef. The name is derived from the Old High German BrÃ¤twurst, from brÃ¤t-, finely chopped meat, and Wurst, sausage, although in modern German it is often associated with the verb braten, to pan fry or roast.
Cold viruses have been shown to survive on indoor surfaces for approximately seven days. Flu viruses, however, are active for only 24 hours. All viruses have the potential to live on hard surfaces, such as metal and plastic, longer than on fabrics and other soft surfaces. In fact, infectious flu viruses can survive on tissues for only 15 minutes. Viruses tend to also live longer in areas with lower temperatures, low humidity, and low sunlight.
The viruses that cause viral hemorrhagic fevers live naturally in a variety of animal and insect hosts â most commonly mosquitoes, ticks, rodents or bats. Each of these hosts typically lives in a specific geographic area, so each particular disease usually occurs only where that virus's host normally lives. Some viral hemorrhagic fevers also can be transmitted from person to person, and can spread if an infected person travels from one area to another.
