Everything is very clear and understandable. I like posts that fill in your knowledge gaps. This one is of the sort. Click here to cancel reply. Name required. Email will not be published required. Take a look: Germs can survive for up to three hours on your hands. There are between 2 to 10 million bacteria on your fingertips and elbows. The number of germs on your fingertips doubles after you use the toilet.
Your hands spread 1, times more germs when they are damp than when they are dry. Why are germs so bad? Nearly 80 percent of illness-causing germs are spread by your hands. Your remote control is a top carrier of bacteria. There are more germs on your phone, keyboard and cutting board than on a toilet seat. When you flush the toilet, germs can spray up to 6 feet. Purses and handbags have up to 10, bacteria per square inch, and 30 percent of them contain fecal poop bacteria.
The CDC has this down to a science: Get your hands wet, turn off the water, and apply soap. Rub your hands together to lather up the soap. Clean every surface from between your fingers and under your nails to your palms and back of your hands. Scrub for at least 20 seconds. Turn the water back on and rinse well. Dry your hands with a clean towel and use the towel to turn off the water.

September 16, at pm. What is the goal of a virus? Once a virus finds the perfect host, the goal is to reproduce and spread. Imagine that a virus makes a home in the cells that make up your blood. Then, it can hitch a ride just about anywhere in the body, and spread itself around. Some viruses will make a home inside a cell and grow and grow until the cell bursts, spreading the virus around to find new "home" cells.
Viruses are pretty sneaky because they can mutate change quickly to adjust to a new environment. Fungi are kind of like plants and are made up of many cells.
You've heard of mushrooms and yeast. These are types of fungi. The reason that fungi are not called plants is because they cannot produce their own food from soil, water and sun, like green leafy plants plants can photosynthesize. Instead, fungi live off of animals and other plants. Have you ever seen a tree with fungus growing on it? The fungus survives by living on the tree. So how does a fungus make a home on a human? Fungi love damp warm places, like the underside of a rock or those sweaty cracks between your toes.
Of course, the fungus that can make its home on your skin does not sprout out like a mushroom, but it is similar to a mushroom in that all fungi are made up of spores that bud like plants to produce more spores.
This is how the fungi can spread. Most fungi are harmless. The kind that can grow on your skin can be treated and looks much like a rash. It probably won't hurt you, but it is really itchy! You can catch a fungus by walking barefoot where it likes to live, like in the school gym locker room. Wash your hands with soap and water when your hands are visibly soiled.
Food handlers in restaurants, schools, delis and grocery stores must wash their hands with soap and water before applying hand sanitizers.
