Peaking in January and February, Respiratory syncytial virus is the virus causing most common colds, when it is limited to the upper respiratory tract. Unfortunately when the virus aggravates the lower respiratory tract, complications occur, including respiratory distress, pneumonia, bronchiolitis and possibility the development of asthma. Pruitt also states that each year 125,000 children (mostly under 6 months of age) require hospitalization, and of these, about 2,500 die (Pruitt 63). Beyond this age, by about two years old, children have been exposed to RSV and have developed and immunity. If diagnosis of this infection is made through cultures of respiratory secretions, treatment begins immediately.
Unit 9 Shigella Shigella infection (shigellosis) is an intestinal disease caused by a family of bacteria known as shigella. The main sign of shigella infection is diarrhea, which often is bloody. Shigella can be passed through direct contact with the bacteria in the stool. For example, this can happen in a child care setting when staff members don't wash their hands well enough after changing diapers or helping toddlers with toilet training. Shigella bacteria also can be passed in contaminated food or by drinking or swimming in contaminated water.

Back before the 1890’s Clostridium perfringens used to be known as Clostridium welchii. F.W. Andrews and E. Klein discovered that Clostridium perfringens was associated with food poisoning, and in just a couple years specifically 1892, this microorganism would be found in different types of gangrene, appendicitis, puerperal fever, and enteritis. (3) .. Gas gangrene was very widespread in World War 1, complicating 6% of open fractures and 1% of all open
It infects nearly 2% of adults and 6% to 8% of children in developed countries worldwide. Nearly 33% of people in developing countries have had giardiasis. In the United States, Giardia infection is the most common intestinal parasitic disease affecting humans [1]. Giardia infection can cause a variety of intestinal symptoms, which include: Diarrhea, Gas or flatulence, Greasy stool that can float, Stomach or abdominal cramps, Upset stomach or nausea and dehydration. Symptoms of giardiasis normally begin 1 to 3 weeks after becoming infected.
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.
Diarrhea is seen in approximately 10 to 20 percent of patients. After 2 to 7 days, SARS patient may develop a dry, nonproductive cough that might be accompanied by hypoxia. In 10 to 20 percent of cases, patients require mechanical ventilation. Most patients develop pneumonia. The disease is spread by close person-to-person contact through direct contact with respiratory secretions and/or body fluids of an infected individual.
Epidemic Outbreak of “The Herpes Virus” (Assignment #1) Herpes is an infection caused by the etiologic agents Herpes Simplex Virus-1 and HSV-2. HSV-1 is the type generally known for causing oral herpes outbreaks, also known as cold sores or fever blisters. These blisters last from a week to a month, becoming open sores that crust over with scabs. The outbreak following the initial infection (usually a few days to a few weeks afterward) is usually the worst—the ones after that are less painful. Some people actually confuse their mild outbreaks with other skin conditions such as “eczema”.
If an infection is the reason for the pain, there would be nausea, fever, vomiting, cramping and constipation. Diverticula is common in people after 40 years of age. When you have inflamed diverticula, the condition is known as diverticulosis. You may never even know that you have these pockets because they rarely cause any problems as severe as diverticulitis. Diverticulitis usually gets worse throughout the first day.
Most children who develop asthma have a family history of allergies. Early damage to the lungs caused by cystic fibrosis, premature birth, artificial ventilation in an intensive care unit, and certain viral illnesses (especially respiratory syncytial virus [RSV]) can also cause a predisposition to asthma. The severity of asthma varies greatly from child to child. Mild cases may involve only a cough associated with exercise or at night. The milder forms of the disease are the most common, but asthma in its most severe form can result in a catastrophic shortness of breath that leads to death Many simple steps can be taken to reduce asthma triggers in a child's home.
