What is allergic rhinitis? Allergic rhinitis, often called allergies or hay fever, occurs when your immune system overreacts to particles in the air that you breathe—you are allergic to them. Your immune system attacks the particles in your body, causing symptoms such as sneezing and a runny nose. The particles are called allergens, which simply means they can cause an allergic reaction. People with allergies usually have symptoms for many years.
What causes it? • Chicken pox is caused by a very contagious infection caused by the varicella-zoster virus. • It is an airbourne virus, which means it is easily and rapidly spread through sneezing and coughing. Droplets of water expelled from the nose and mouth of the infected person are inhaled by those around them • The infection may also be caused by direct contact with the secretions from the blisters. • The varicella virus has an incubation period of between 10 and 21 days.
ICO2 Headlice Explain how the following can be transmitted from one person to another Head Lice Head lice (pediculus humanus capitis) feed on blood, primarily on the heads of children. Infestation by head lice is called pediculosis. Fortunately, they do not transmit disease, although their presence can be very bothersome. These lice inject a saliva into their hosts as they feed to prevent the blood from clotting. This results in itching which at best is annoying and at worst can result in infection if scratched too vigorously.
Accidents and injuries Task1 Common accidents and injuries that occur to children and young people: 1. Falls from height (furniture, stairs, play equipment, slippery floors) which can led mostly to head injuries. 2. Burns and scalds ( sunburns, electrical, caused by lamps, matches, lighters, cigarettes, fireplaces, hot liquids) 3. Ingestion – poisoning ( from ingestion medicines, shampoo, cleaning products) 4.
Some people actually confuse their mild outbreaks with other skin conditions such as “eczema”. Early after infection, some people experience prodrome, a tingling, itching feeling that occurs in an area where blisters will shortly develop. Contrary to popular belief, both types can cause genital herpes (Osondu). Transmission is made during contact with a sore or fluid from an infected person, including fetal infection during birth when sores are present on the mother. The reservoirs of the virus are typically ocular, oral, or genital epithelial cells (Hodge).
Hookworm lives in the small intestine of hosts such as humans, cats and dogs, where it is able to mate and mature. Ancylostoma duodenale is abundant throughout the world like Europe, North Africa, India, china, Southeast Asia, Caribbean, South America, and some part of the United State. Hookworm is a small cylindrical worm, they are greyish white in color. The size of the males are 8 mm to 11 mm long. While, the females are 10 mm to 13 mm long.
There are about 9000 species of annelid known today. The ascaris are an intestinal worm, resembling earthworms in size and appearance. MATERIALS: * Dissecting pins * Gloves * Forceps * Lab apron * Scissors * Paper towel * Scalpel * Water * Dissecting probe * Preserved earthworm * Hand lens * Dissection tray PROCEDURE: We first put on our lab aprons, gloves, and (for the girls) make sure your hair is pulled back. We get the dissection tray and place the earthworm. Grab two dissecting pins and place them one on each end of the earthworm.
Mollluscum contagiosum is a viral disease caused by mollusci pox virus, which is virus. The virus is contagious through direct contact and is more common in children. Molluscum contagiosum is most common in children ages 1 to 10. However, the virus also can be spread by a DNA sexual contact and can occur in people with compromised immune systems. It is spread through direct contact or shared items such as clothing or towels.
* Burns or scalds to the child’s skin * Meningitis symptoms such as a stiff neck, fever, headache and a rash that doesn’t fade when pressed by a glass. * Confusion, headache, vomiting or blurred vision after a head injury. * Being floppy, unresponsive or unconscious. * Difficulty breathing and blueness around the lips. * Having a high fever, heat exhaustion or severe sunburn.
Coughing and sneezing can spread contagious pink eye by spraying tiny droplets from infected mucus into the air. Shared towels also can be infected, as well as table tops, counter spaces and bathrooms. Pink eye can occur in adults, but most often affects young children through epidemics that spread rapidly in classrooms and day care centers. Particularly in these communal settings, you need to take extra precautions to prevent pink eye, such as frequent hand washing by adults and children. In fact, when pink eye symptoms are present, it's a good idea to keep a can of disinfectant spray handy and use it often.
