As the cases of swine flu are incresing all over the world and there is a lot of panic about it.Vikram hospital wants to inform you some of the information about this flu so that people get relax about it
When we usually talk about swine flu people just feel that this is come new discovered virus invading the earth like how HIV and SARS did. But the history of this swine flu is more than half a century old.
Actually swine influenza was first proposed to be a disease related to human flu during the 1918 flu pandemic, when pigs and humans fell ill at the same time. About ten years later, the first identification of an influenza virus as a cause of disease in pigs occurred, in 1930. For the following 60 years, swine influenza strains were almost exclusively H1N1. In 2011, a new swine flu virus was detected. The new strain was named influenza A (H3N2)v but only a few people (mainly children) were first infected by this newly discovered strain. Unfortunately, another virus termed H3N2 (note no “v” in its name) has been detected and caused flu, but this strain is different from H3N2v. In general, all of the influenza A viruses have a structure similar to the H1N1 virus; each type has a somewhat different H and/or N structure.
Like most influenza infections the symptoms of swine flu are fever (100 F or greater), cough, nasal secretions, fatigue, and headache with fatigue being reported in most infected individuals. Some patients may also get a sore throat, rash, body aches, headaches, chills, nausea, vomiting, and diarrhoea.
When we talk about the treatment for swine flu, most cases require only symptom relief. If you have a chronic respiratory disease, your doctor may prescribe additional medication to help relieve your symptoms.
The antiviral drugs oseltamivir (Tamiflu) and zanamivir (Relenza) are sometimes prescribed to reduce the severity of symptoms, but flu viruses can develop resistance to them.
There is currently no vaccine available against human swine influenza. One has to follow proper hand hygiene practices like the following ones
- Avoid close contact with people who are having respiratory illness.
- Sick persons should keep distance from others.
- Cover your mouth and nose with a tissue or handkerchief when coughing or sneezing.
- Washing your hands often with soap or alcohol based hand wash will help protect from germs.
- Persons who develop influenza-like-illness (ILI) (fever with either cough or sore throat) should be strongly encouraged to self isolate in their home for 7 days after the onset of illness or at least 24 hours after symptoms have resolved, whichever is longer.
- If ill persons must go into the community (e.g., to seek medical care) they should wear a face mask to reduce the risk of spreading the virus in the community..
- Persons in home isolation and their household members should be given infection control instructions like frequent hand washing with soap and water; use of alcohol-based hand gels (containing at least 60%alcohol).
- When the ill person is within 6 feet of others at home, the ill person should wear a face mask, if available or handkerchief or tissues.
