Fever in AdultsA fever is a body temperature of 100.4 F or greater. A fever may be caused by a virus, bacteria, fungus, blood clot, tumor, drug, or the environment. Treatment of fever in adults usually involves ibuprofen, acetaminophen, or aspirin.
Fever in ChildrenFever is defined as a rectal temperature over 100.4 F or 38 C. Fever isn't life-threatening unless it is persistently high - greater than a 107 F rectal temperature. Fever is usually caused by an infection. Treatment focuses on controlling the temperature, preventing dehydration, and monitoring for serious illness.
Flu in AdultsFlu (influenza) is an acute infection of the nose and throat airways. This infection may spread to the lungs. Flu is the most frequent cause of acute respiratory infection in people of all ages. Symptoms of the flu include fever, severe aches and pains, headache, dry cough, sore throat, and at times vomiting and nausea. Treatment for the flu includes home remedies such as OTC pain relievers, rest, and hydration. Medical treatment for the flu includes antiviral medications.
Flu in Children HealthChildren may become infected with influenza by inhaling infected droplets in the air or if they come in contact with secretions from an infected person. Symptoms in children include a high-grade fever up to 104 F, chills, headaches, sore throat, cough, and muscle aches. Treatment of flu in children involves rest, increased fluid intake, treating fever with acetaminophen or ibuprofen, using a humidifier, and using a rubber suction bulb to remove nasal secretions in younger children.
Guillain-Barre SyndromeGuillain-Barre syndrome is a disorder of the nervous system in which the myelin sheath that insulates nerves deteriorates, causing loss of sensation and muscle weakness. The cause of the disease, also called polyneuropathy, is unknown. Doctors theorize it is an autoimmune disorder, however. Treatment includes supportive care and plasmapheresis.
H1N1 Nasal Spray VaccineThe H1N1 nasal spray vaccine 2009 is an attenuated (live virus) vaccine to prevent the H1N1 influenza (swine flu). There are certain groups of individuals who should not receive this vaccine.
Sore ThroatSore throats are generally named for the anatomical site affected, such as: the pharynx, tonsils, adenoids, larynx, and epiglottis. Sore throat treatment depends on the cause, infection, viral, or fungal.
Swine FluPrior to 2009, swine flu was a form of influenza that predominately affected swine. The virus was not easily transmitted to humans. However, the swine flu virus has mutated, allowing for person-to-person transmission. Swine flu symptoms include fever, sore throat, and cough. Infected individuals may also experience fatigue, headache, chills, or body aches. Lab testing is needed to confirm a diagnosis of swine flu. Treatment may involve oseltamivir or zanimivir.
