H1N1 Flu (Swine Flu)

Responsible for binding the virus to host cells is called the HA (hemagglutinin) peplomer while the virus that allows to break its bonds to the host cell once it is ready to move on is called the NA (neuraminidase) peplomer. This type is also called H1N1 Flu or well-known as Swine Flu. Swine flu is a type of virus infected from pigs. Humans do not normally get swine flu, but human infections can and do happen.

But, randomly, the human race got infected with Swine flu. Most frequently, these cases occur in persons with direct exposure to pigs (example: owner and or workers in the swine backyard or industry or even the children near pigs at a fair).

The virus is contagious and can spread from human to human. Symptoms of swine flu in people are similar to the symptoms of regular human flu such as cough, fever, body aches, sore throat, chills, fatigue and headache.
Swine Flu is a respiratory track infection from the hogs. This kind of virus can kill the human race just like what happen to a pregnant woman and another individual in Texas with also reported death in Washington. This infection is a worldwide virus outbreak that started in Mexico and eventually spread from one country to another continent including China.

A flu deadly disease occurs when a new influenza virus emerges for which people have little or no immunity at all and those whom their hospitals are more than 10 to 20 miles from their community can easily infected with the Swine Flu. The transmission of human to human of Swine flu can also be done.

This is thought to happen in the same way as seasonal flu occurs in people, which is mainly through coughing or sneezing of people infected with the influenza virus to an uninfected individual will be infected also. People may also become infected by touching something with flu viruses on it and then they touch their mouth or nose. The disease spreads easily by human to human transmission and can be cause with serious sickness, and can spread to other individuals in your community, spread out across the country and even worldwide in a very short period of time.

A big NO-NO to some individuals who think that swine flu can also get from foods we eat. Take note that influenza viruses cannot be transmitted by food by means of eating pork or pork products. Eating properly handled and properly cooked pork is safe.

Swine Flu can be monitor if you consult to your health officer directly if you are not feeling well for more than 24 hours especially if you have a hog race industry in your backyard. They will advice you on how to plan, prepare and prevent the Swine Flu virus that spread out worldwide.

An Overview of Swine Flu

Swine flu or influenza is a condition caused by strains of subtypes of Influenza A virus called H1N1, H1N2, H3N1, H3N2, and H3N3. These viruses are common in pigs located in midwestern United States, Canada, South America, Mexico, Mainland China, Japan, Taiwan, Europe, and other Eastern Asian countries.

Transmission of influenza virus from swine to humans is relatively uncommon and does not always result to human influenza but often leads to production of antibodies in the blood. When properly cooked, pig meat does not have the potential of passing the virus. Transmission that leads to human influenza is called zoonotic swine flu.

People who work with pigs, particularly those with direct exposure, are at greater risk of being infected with swine flu. Towards the middle of the 20th century, identification of influenza subtypes became likely paving the way for an accurate diagnosis of transmission to humans. Since then, 50 infections have been confirmed and recorded.

It is rare for these strains of swine flu to be transmitted from one human to another. In humans, the symptoms of swine flu are similar to common influenza as well as influenza-like illness such as chills, sore throat, fever, coughing, muscular pains, severe headache, and general discomfort.
The 2009 swine flu outbreak in humans was caused by a new strain of influenza A virus subtype H1N1 which have genes that closely resemble swine influenza. The root of this new strain is not known. According to the World Health Organization for Animal Health, this new strain has not been isolated in pigs. It is capable of human-to-human transmission and manifests the normal symptoms of influenza.

Swine can be infected with human influenza such as the case of the 1918 flu pandemic and the 2009 flu outbreak. Swine flu was first proposed as a disease associated with humans during the 1918 flu pandemic. During that time, pigs became simultaneously sick with humans.

Influenza virus as a cause of disease in pigs was first identified in 1930. For the next six decades, strains of swine influenza became almost exclusively H1N1. From 1997 to 2002, new strains of three varied subtypes and 5 different genotypes were identified as the cause of influenza among pigs in North America.

From 1997-1998, H3N2 strains developed. They included genes acquired through reassortment of human, avian, and swine viruses and have been a principal cause of wine influenza in North America. Reassortment between H1N1 and H3N2 resulted to the development of H1N2. In Canada, a strain of H4N6 resulted from the reassortment of avian and swine flu but was isolated on a single farm.

The H1N1 variant of swine flu is one of the descendants of the strain that brought about the 1918 flu pandemic. While persisting in pigs, the descendants of the 1918 virus have also been transmitted throughout the 20th century which resulted to the usual seasonal influenza outbreaks.
It is interesting to note that direct infection from pigs to humans is rare, with only 12 confirmed cases in the United States since 2005.

However, since the influenza strains remain in the pigs after they have disappeared in the human population can make these pigs a reservoir where the influenza virus could survive and later on transmitted to humans as soon as their immunity to the strain is no longe effective.

Swine flu has been recorded as zoonosis in humans several times, oftentimes with limited distribution and rarely with massive distribution. Swine outbreaks are common and can lead to significant economic losses in the industry, mainly leading to stunting and expanded market time. Swine influneza, for instance, the British meat industry has experienced 65 million of losses annually.

An Introduction To Swine Flu

Swine Flu-Is a respiratory track infection from the hogs. This kind of virus can kill the human race. This infection is a worldwide virus outbreak. A flu deadly disease occurs when a new influenza virus emerges for which people have little or no immunity and for which there is no vaccine. Those whom their hospitals are more than 10 miles from their community can easily infected with the Swine Flu.

The disease spreads easily person-to-person, and can be cause with serious illness, and can spread out across the country and even worldwide in a very short span of time. An influenza pandemic may be caused by either swine (pig) or avian (bird) flu viruses.

Swine flu viruses do not normally infect humans. But, randomly, the human race got infected with Swine flu. Most frequently, these cases occur in persons with direct exposure to pigs (example: owner and or workers in the swine backyard or industry or even the children near pigs at a fair).

Human-to-human transmission of Swine flu can also occur. This is thought to happen in the same way as seasonal flu occurs in people, which is mainly through coughing or sneezing of people infected with the influenza virus to an uninfected individual will be infected also. People may also become infected by touching something with flu viruses on it and then they touch their mouth or nose.

Some think that swine flu can also get from foods we eat. Take note that influenza viruses are not transmitted by food. You cannot get the influenza virus by means of eating pork or pork products. Eating properly handled and cooked pork is safe. Proper cooking of pork or pork products with an internal temperature of 160F will kill the swine flu virus as it does with other bacteria and viruses.

Fever, lethargy, lack of appetite, runny nose, sore throat, nausea, vomiting, diarrhea and coughing are some of the following symptoms of swine flu in people.

In diagnosing influenza infection, a respiratory specimen would generally need to be collected within the first 3 to 4 days of illness (when an infected person is most likely to be contagious). However, some persons, especially children, may be infectious for 10 days or longer.

If you get sick, there are two antiviral drugs (Tamiflu and Relenza) available with prescription can make your illness milder and make you feel better faster. They may also prevent serious influenza complications. In treatment, antiviral drugs work best if started as soon after getting sick as possible, and might not work if started more than 2 days after illness starts.

There are a number of things that you can do to prepare yourself and those around you for a flu pandemic. It is important to think about the challenges that you might face, particularly if an epidemic is rigorous.

The effects of a pandemic can be lessened if preparation is made ahead of time. Planning and preparation information and checklists are being prepared for various sectors of society, including information for individuals and families.

Different agencies are providing funding, advice, and other support from different rich nations to every country to assist with Swine Flu epidemic planning and preparation. Reading articles like this can help you plan against the spreading of the Swine Flu.

Swine Flu: Overview, Treatment, and Prevention

Swine flu is an illness that is affecting hundreds of individuals in the United States as well as worldwide. According to the CDC, the illness may take some more time. Since one is likely to become infected with the condition, they need to understand swine flu symptoms in order for them to obtain proper treatment or medicaion.

The Symptoms

The symptoms of H1N1 infection is similar to that of seasonal flu. Among the symptoms include cough, sore throat, running or stuffy nose, chills and fatigue, to name just a few. Several people infected with the virus have complained of diarrhea and vomiting. The high risk groups prone to H1N1 is not yet known at the moment but it is likely that they are similar to those suffering from seasonal influenza.

People at greater risk of serious side effects from seasonal flu include people more than 65 years old, children below 5 years old, pregnant women, and people with chronic medical consitions as well as those who are taking immunosuppressive medications or with HIV infection.

Avoid Social Contact

If you are feeling sick, your condition may last for more than a week. You should remain at home and refrain from making social contact. As much as possible, you should not communicate with other people to avoid the spread of the virus.

At the moment, the CDC believes that H1N1 has similar properties on the aspect of transmission with seasonal flu virus. If you go out of the house to consult your doctor, wear a mask or use a tissue when coughing or sneezing.

According to recent studies, people suffering from seasonal flu are at risk to transmit the disease a day prior to development of symptoms for up to seven days after getting sick.

Children are more likely to be at risk for a longer period of time so it is best to consult a healthcare provider.

Emergency Warning Signs

If you suddenly become sick and experience any of the following warning signs, this is your cue to seek emergency medical assistance.

In the case of children becoming ill due to H1N1infection, the following warning signs may require immediate medical attention:

* Fast or difficulty in breathing
* Bluish or gray colored skin
* Insufficient amount of liquids
* Severe or continuous vomiting
* Lack of sleep or interaction
* Irritability
* Recovery from flu-like symptoms but the symptoms come back with fever and worse coughing

Among adults, the following emergency warning signs demand immediate medical attention:

* Trouble with breathing or shortness of breath
* Abdominal pains or pressure in the chest
* The individual suddenly becomes dizzy
* The patient is confused
* Severe or continuous vomiting
* Recovery from flu-like symptoms but the symptoms come back with fever and worse coughing

Prevention Is The Best Treatment

You can do your part in preventing the spread of the H1N1 virus. Here are some tips on how you can take part in efforts for preventing the spread of infection.

* Be aware. Obtain information about H1N1 by visiting the website of the CDC.

* Use a tissue in covering your mouth and nose when sneezing. Afterwards, throw the tissue in the trash.

* With soap and water, wash your hands after coughing or sneezing. If possible, use alcohol-based sanitizers.

* Refrain from touching your nose or mouth as this could lead to easy transmission of germs.

By being aware of swine flu symptoms, the spread of the H1N1 virus would easily be prevented.
