The crawling of the female worm on the skin around the anal area often produces intense itching causing a person to scratch there, getting the eggs on the hands. Without washing, the hands touch the mouth. Now the eggs are swallowed and hatch in the lower colon where the pinworms mate, and cycle continues. The eggs are usually found on the infected person's pajamas and bed linen. Children can easily infect the entire family through the bathtub, toilet seat, and bedclothes.
The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves.
The Hertz Corporation, originally known as Rent-a-Car Inc., was founded by Chicago, Illinois native Walter L. Jacobs in 1918. This small car rental operation began with a dozen Model T Ford cars. Within five years, Jacobâs fleet expanded to 600 vehicles - generating annual revenues of approximately $1 million USD.
