Processed Foods. Processed foods tend to have a lot of sodium, and people with hypothyroidism should avoid sodium, Frechman says. Having an underactive thyroid increases a person's risk for high blood pressure, and too much sodium further increases this risk.
Yellow fever is caused by the yellow fever virus (YFV), also called Flavivirus. The virus is transmitted by female mosquitos, who pick it up from monkeys or other humans, then delivers it to a new human when they bite and suck blood. The disease cannot be spread from person to person. Mosquitoes breed in tropical rainforests, humid and semi-humid environments, and around bodies of still water.
Yellow fever is a viral disease spread to humans, as well as between certain other primates and humans, by the bite of infected mosquitoes. The virus is called simply Yellow fever virus, named for the jaundice that affects some patients, and belongs to the virus family Flaviviridae. Yellow fever is endemic in areas of Latin America and Africa, while imported cases have appeared throughout the world.
