Which Group of Virus Does Influenza

Influenza, or “flu,” is also caused by a virus. There are three primary strains of the influenza virus: A, B, and C. Most influenza develops from the A and B strains. These strains can change genetically, reappearing in an altered form every few years. Symptoms of all types of flu include chills, fever, weakness, headache, sore throat, dry cough, nausea, vomiting, and muscular aches and pains. All symptoms may not be present, and the severity varies greatly among people. Treatment for flu is the same as for the common cold. Aspirin should not be taken by children or teenagers because the potentially fatal Reye’s syndrome can develop.Vaccines are available that can prevent a particular type of influenza. Current recommendations are that priority should be given to children and adults with chronic cardiovascular and lung disorders, residents of nursing homes, medical personnel who may transmit the virus to high-risk patients, everyone over 65, and anyone with conditions such as diabetes, kidney disease, hereditary anemias, and impaired natural immunity.

Gastrointestinal Defects

Birth defects, also known as "congenital abnormalities," are structural defects in some part or system of the body that can affect the body's function. These congenital defects occur during fetal development, and are present in a baby from birth. Like other complex body systems, the gastrointestinal system (or digestive system), responsible for digestion and extracting nutrients from food, is vulnerable to congenital defects during its development. Healthy Gastrointestinal Tract Function The gastrointestinal system is made up of several organs, including the: Mouth Esophagus Stomach Small intestine: Duodenum, jejunum and ileum Large intestine: Cecum, colon, rectum and anus.
