Influenza or Flu

Influenza or Flu

Influenza is an infectious disease of the respiratory tract caused by the influenza virus. The disease generally lasts 3-7 days. It is characterized by fever, cough, and considerable muscle ache (myalgia). It is sometimes complicated by secondary bacterial pneumonia. Flu starts abruptly, usually with a fever up to 39.4C (103F) in adults and higher in children. The illness may be followed by a period of weakness and depression.

The incidence of infection is highest among school-age children. This may be because they lack previous exposure. Infection is probably transmitted as a small-particle aerosol. A high proportion of the infected individuals does not develop symptoms but are probably symptoms but are probably capable of transmitting infection to others.
Persistent fever or worsening symptoms may indicate one of three types of the pneumonia form of influenza. The first is sudden, sever and often fatal and is present from onset; the second, less sever, appears a few days after onset; and the third, also less sever, appears after apparent recovery.

It was observed that influenza epidemics characterized by cough and fever occurred more frequently at certain times of the year. Even today, the seasonal factors in influenza are still observed both in the temperature and tropical countries. But the seasonal influence is still poorly understood.

Treatment and Medications

Bed rest and plenty of fluids constitute the best treatment. Aspirin may be given to adults but not to children, because children are at risk of developing Reye’s syndrome. Flu victims, 50 years old or older, however, may be given antibiotics to prevent pneumonia. An attack of influenza produces a temporary immunity, but unfortunately the protection is against only the type of virus causing that same influenza. It is not effective for another influenza strain.

Vaccines have been developed that have been found to be 70-90 percent effective for the at least 6-8 months against either A or B types, and genetically engineered live-virus vaccine is under development. Vaccination is considered especially important for older people, patients with cardiac or respiratory diseases, and pregnant women.

Since 1984, vaccination is also given to the medical personnel and staff and the public who desire for protection from influenza. But routine or annual vaccination is not recommended. It is only administered during outbreaks and for high-risk groups because of the periodic changes in influenza viruses.

Today, Centers for Disease Controls and some government and non-government organizations recommends the use of Amantadine Hydrochloride for therapy and as an adjunct to immunization for high-risk patients. Amantadine Hydrochloride is effective against types A influenza infections but is not effective against type B.

We had the flu in my house
a few months back,
it was just awful.
The only thing that saved me a lot of pain and anguish,
was having my pneumonia shot.
I have to get a booster shot next week.
It has been 9 years and
they are good for up to 10 years.
Nice article.
Thanl you for sharing.:)

Influenza is not common in tropical countries I feel. It takes a toll in colder countries though, especially the elderly are vulnerable - siva
