Stig Kristoffersen asked:


Swine flu refers to influenza caused by those strains of influenza virus that usually infect pigs and are called swine influenza virus (SIV). Swine influenza is common in pigs in the M?d-West of the United States and some other states, Mexico, Canada, South America, Europe, Kenya, Mainland China, Taiwan, Japan and other parts of eastern Asia.

Transmission of swine influenza virus from pigs to humans is not common and properly-cooked pork poses no risk of infection. When transmitted, it does not always cause human influenza and often the only sign of infection is the presence of antibodies in the blood which are only detectable by laboratory tests. When transmission results in influenza in a human, it is called zoonotic swine flu. People who work with pigs, especially people with intense exposures, are at risk of catching swine flu. However, only about fifty such transmissions have been recorded since the mid-20th Century, when identification of influenza subtypes became possible. Rarely, these strains of swine flu can pass from human to human. In humans, the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general, namely chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort.

The 2009 flu outbreak in humans, known as “swine flu”, is due to an apparently virulent new strain of influenza A virus subtype H1N1 that contained many genetic elements normally found in swine influenza. The origin of this new strain is unknown, and the World Organization for Animal Health (OIE) reports that this strain has not been isolated in pigs. It can be transmitted from human to human, an ability attributed to an as-yet unidentified mutation. This 2009 H1N1 strain causes the normal symptoms of influenza, such as fever, coughing and headache.

The 2009 flu outbreak is due to a new strain of influenza, an apparent reassortment of at least four strains of influenza A virus subtype H1N1, including one strain endemic in humans, one endemic in birds, and two endemic in swine. Although initial reports identified the new strain as swine influenza (ie, a zoonosis), its origin is unknown. Several countries took precautionary measures to reduce the chances for a global pandemic of the disease.

This new strain had not previously been reported in pigs. On May 2, 2009, H1N1 was reported in pigs at a farm in Alberta, Canada, with a link to the 2009 swine flu outbreak in Mexico. The pigs are suspected to have caught this new strain of virus from a farm worker who recently travelled to Mexico, then showed symptoms of an influenza-like illness. These are probable cases, pending confirmation by laboratory testing.

The time and location of the outbreak is still unknown, but it was first detected in two cases in Southern California in late March. When this novel virus was publicized, officials in Mexico suspected a link to an outbreak of late-season flu cases they were finding. Mexican news media report that the outbreak may have started in February near a Smithfield Foods pig plant amid complaints about its intensive farming practices. Within days, hundreds more suspected cases were discovered in Mexico, with more cases also showing up in the U.S. and several other countries. By late April, officials from the U.N.’s World Health Organization (WHO), based in Switzerland, and the Centers for Disease Control and Prevention (CDC) in the U.S., were expressing serious concern about the flu outbreak, worried that it might become a worldwide flu pandemic.

The new strain has spread widely beyond Mexico and the U.S., with confirmed cases in eighteen countries and suspected cases in forty-two. Many countries have advised their inhabitants not to travel to infected areas. Countries including Australia, China, Iceland, India, Indonesia, Malaysia, Philippines, Singapore, South Korea and Thailand are monitoring visitors returning from flu-affected areas to identify people with fever and respiratory symptoms. Many countries have also issued warnings to visitors of flu-affected areas to contact a doctor immediately if they had flu-like symptoms.

Mexico’s schools, universities, and all public events will be closed from April 24, 2009 to May 6, 2009. By May 3, 2009, more than 400 schools in the U.S. closed due to confirmed or probable cases in students or staff, affecting 250,000 students

By April 28, the new strain was confirmed to have spread to Spain, the United Kingdom, New Zealand, and Israel, and the virus was suspected in many other nations. As a result, WHO raised its alert level to “Phase 5″ out of 6 possible, which it defines as a “signal that a pandemic is imminent” By the end of April, 300 schools had closed across the United States and the Mexican government ordered a multi-day shutdown of all non-essential activities in the government and private sector, amounting to a shutdown of most of the country’s economy. At the same time, however, many scientists were reaching a consensus that the epidemic was so far “relatively mild,” and believed that it could be less fatal than previous pandemics.

The new strain is an apparent reassortment of four strains of influenza A virus subtype H1N1. Analysis by the CDC identified the four component strains as one endemic in humans, one endemic in birds, and two endemic in pigs (swine). However, other scientists have stated that analyses of the 2009 swine flu (A/H1N1) viral genome “suggests that all segments are of swine origin”, “we are puzzled about sources of information that affirm that the virus is a reassortment of avian, human and swine viruses,” and “this preliminary analysis suggests at least two swine ancestors to the current H1N1, one of them related to the triple resorting viruses isolated in North America in 1998.” One swine strain was widespread in the United States, the other in Eurasia. Worldwide the common human H1N1 influenza virus affects millions of people every year, according to WHO officials, and “these annual epidemics result in about three to five million cases of severe illness, and about 250,000 to 500,000 deaths” annually. In industrialized countries most of these annual deaths occur in people aged 65 or older. By May 2, some pigs in Canada were diagnosed with H1N1. Although some influenza strains can spread between species, the influenza virus is killed by normal cooking procedures, so there is no risk of infection from consumption of well-cooked pork and pork products.

Recommendations to prevent infection by the virus consist of the standard personal precautions against influenza. This includes frequent washing of hands with soap and water or with alcohol-based hand sanitizers, especially after being out in public. The CDC advises not touching the mouth, nose or eyes, as these are primary modes of transmission. When coughing, they recommend coughing into a tissue and disposing of the tissue, then immediately washing the hands.

Of the available antiviral treatments for influenza, the WHO stated that the viruses obtained from the human cases with swine influenza in the United States were sensitive to oseltamivir (Tamiflu) and zanamivir (Relenza) but resistant to amantadine and rimantadine. Tamiflu and Relenza also have a preventative effect against Influenzavirus A. On April 27, the CDC recommended the use of Tamiflu and Relenza for both treatment and prevention of the new strain. Roche and the U.S. government had already extended the shelf life of federally stockpiled Tamiflu from the original five years to seven years because studies indicated that the medication continues to maintain its effectiveness.

ng>Swine Flu Symptoms

The symptoms of swine flu in people are expected to be similar to the symptoms of regular human seasonal influenza and include fever, lethargy, lack of appetite and coughing. Some people with swine flu also have reported runny nose, sore throat, nausea, vomiting and diarrhea. Symptoms of Swine flu may including all or some of the following:

Fever Muscle aches Lethargy Coughing Headache Sore throat Runny nose Nausea Vomiting Diarrhea Lack of appetite Complications Of Swine Flu

Those at higher risk of catching influenza in general include those with the following:

* Age of 65 years or older

* Chronic health problems (such as asthma, diabetes, heart disease)

* Pregnant women

* Young children

But the past epidemics and pandemics of flu have shown that during pandemics most people that are affected are healthy young adults.

Complications of Swine Flu can include:

* Pneumonia

* Bronchitis

* Sinus infections

* Ear infections

* Death

Transmission of Swine Flu (How is Swine Flu spread?)

As with other flu like illnesses, Swine flu is spread as follows:

Coughing Sneezing Kissing Touching infected objects Touching nose, mouth and/or eyes with infected hands Swine flu does not spread by eating pork. Treatment of Swine Flu Swine Flu Vaccination / Swine Flu Shot

The protective ability of influenza vaccines depends primarily on the closeness of the match between the vaccine virus and the epidemic virus, so the presence of non reactive H3N2 SIV variants suggests that current commercial vaccines might not effectively protect pigs from infection with a majority of H3N2 viruses. The current vaccine against the seasonal influenza strain H1N1 is thought unlikely to provide protection. The director of CDC’s National Center for Immunization and Respiratory Diseases said that the United States’ cases were found to be made up of genetic elements from four different flu viruses—North American swine influenza, North American avian influenza, human influenza A virus subtype H1N1, and swine influenza virus typically found in Asia and Europe.

Gelsemium. [Gels]

This remedy corresponds to the commencement of the trouble, when the patient is weak, tired and aches throughout the body. It removes speedily the intense aching and muscular soreness. There is constant chilliness and the patient hugs the fire; the fever is less acute than that of Aconite, and the cough is hard and painful. There are paroxysms of sneezing with excoriating discharge, and great torpor and apathy. An extensive experience with this remedy in the great Epidemic of 1918 proved its usefulness. Simple cases were speedily cured. Aconite will sometimes prove the better remedy for children, but the drug will never be a prominent one in influenza. Still it may be prescribed when indicated; it will, perhaps, soothe and moderate the subsequent attack, but its action is not quick here as in simple fevers, as we have to do with a blood affection.

#Baptisia.

Influenza with marked gastro-intestinal symptoms may need this remedy, especially when there are present putrid diarrhoea stools. Clarke considers this remedy the nearest specific for the disease; he prefers the 30th potency. Hughes also praises it, but uses it in the 1x and 2x dilutions, which seem to have more extensive testimony as to their efficacy.

#Eupatorium perfoliatum.

This remedy has much soreness and aching of the entire body; hoarseness and cough, with great soreness of the larynx and upper respiratory tract. Coryza with thirst and drinking causes vomiting. The cough is a very shattering one, hurts the head and chest, and as in Drosera, the patient holds the chest with the hands. The breakbone pains are characteristic of the remedy. Add to these symptoms acute bilious derangements, and it is all the more indicated. Many physicians rely on this remedy in influenza / flu almost exclusively in the early stages.

#Sabadilla. [Sabad]

Sneezing is the great keynote of this remedy. Sneezing and lachrymation on going into the open air. The throat is swollen and the pain is worse on empty swallowing; the sneezing is excessive, shaking the whole body. Shudderings, with gooseflesh chills creeping upwards, are also prominent symptoms. Frontal headache, dryness of mouth, without thirst and cough, worse on lying down, are additional symptoms. It suits well many cases of the catarrhal form of flu; other remedies having sneezing are Cyclamen and Euphorbia.

#Arsenicum. [Ars]

This remedy covers more phases of flu than perhaps any other remedy. Hughes believes that it will cut short an attack, especially when there is a copious flow, prostration and paroxysmal coryza. Its periodicity makes it suitable to epidemics, and it suits the early symptoms when the affection is in the upper portion of the respiratory tract. The burning dryness and copious watery excoriating secretion and the involvement of the conjunctiva are unmistakable indications. Langour and prostration are prominent symptoms.

#Arsenicum iodide.

Chills, flushes of heat and severe fluent coryza, discharge irritating and corrosive, sneezing and prostration. It corresponds to true influenza and is highly recommended by Hale. Sanguinaria nitrate is especially valuable when the trachea and larynx are affected. Phytolacca. Specific when the throat is inflamed and spotty, with great hardness and tenderness of the glands.

#Dulcamara. [Dulc]

This is one of our best remedies in the acute form; the eyes are suffused, the throat is sore and the cough hurts because of the muscular soreness. If brought on by damp, cold changes in the weather, so much the surer is Dulcamara indicated.

#Bryonia.

The trouble here is largely bronchial and going down. When a person is very grumpy and feels miserable with the flu, wanting only to lie still and be left alone, this remedy is likely to be useful. Headache, muscle aches, and cough or stomach pain may be the major symptoms. Everything feels worse from even the slightest motion. The person’s mouth usually is dry, with a thirst for long cold drinks.

#Phosphorus may be indicated, especially when the trouble moves towards the chest. It is a very useful remedy for the debility following la grippe, as it is usually of the pure nervous type. It is the great post-influenza “tonic.”

#Rhus toxicodendron. [Rhus-t]

Influenza, with severe aching in all the bones, sneezing and coughing. The cough is worse evenings and is caused by a tickling behind the upper part of the sternum. Especially is it useful in cases brought on by exposure to dampness. There is much prostration and depression, and the patient may have some symptoms which are suspicious as pointing towards typhoid fever, such as burning tongue, stupor and delirium. Aching pains, nightly restlessness are keynotes symptoms. Causticum, like both Rhus and Eupatorium, has a tired, sore, bruised sensation all over the body and soreness in the chest when coughing, but it has in addition involuntary urination when coughing.

#Allium cepa. [All-c]

Profuse catarrhal coryza; the nose runs freely, there is sneezing, irritability cough, the face is swollen and looks inflamed. Camphora. This remedy is often sufficient at the outset to cut short an attack, or at least modify the severity.

#Sticta. [Stict]

Nasal catarrh; headache, thirst, nightly expectoration, great watering of eyes,running at nose, hoarseness of voice, frontal headache and depression of whole system. Tuberculous subjects attacked by influenza. “There is no better remedy,” says Dr. Fornias,”for the incessant wearing, racking cough of this class of patients.” Tuberculinum is an excellent prevention of recurring attacks of influenza /flu in those who have annual attacks.

#Ipecac

Adapted to cases where the gastric symptoms predominate; tongue clean or slightly coated. Nausea: with profuse saliva; vomiting of white, glairy mucus in large quantities, without relief; sleepy afterwards; worse from stooping. Low thirst. Cough: dry spasmodic, constricted, asthmatic. Difficult breathing from least exercise; violent dyspnoea, with wheezing and anxiety about the stomach. Cough, with rattling of mucus in bronchi when inspiring; threatened suffocation from mucus. Pains as if bones were all torn to pieces.

#Veratrum album

Adapted to diseases with rapid sinking of the vital forces; complete prostration; collapse. Cold perspiration on the forehead (over entire body, Tab. ); with nearly all complaints. Thirst: intense, unquenchable, for large quantities of very cold water and acid drinks; wants everything cold. Diarrhoea: frequent, greenish, watery, gushing: mixed with flakes: cutting colic, with cramps commencing in hands and feet and spreading all over; prostrating, after fright; < least movement; with vomiting, cold sweat on forehead during and prostration after. Vomiting: excessive with nausea and great prostration: < by drinking ( Ars. ); by least motion ( Tab. ); great weakness after.
