Avian Influenza Incidence Tracking Map, Februa...Image by Quiplash! via Flickr
The United Kingdom has become the latest country to confirm cases of the swine flu. At the same time, the World Health Organization has raised its alert level from 3 to 4. With 150 people already killed in Mexico, the WHO revealed that the influenza virus has the sustainability for human-to-human transmission and can cause community level outbreaks.

One can recall a similar outbreak known as bird flu which was more risky than H1N1 virus. According to Professor Neil Ferguson of the World Health Organization, H1N1 is nothing when compared to other similar outbreaks such as SARS or the 1918 Spanish flu.

According to the professor, the evidence is clear that the United Kingdom is headed for a swine influenza pandemic in the coming months. However, it would be difficult to determine the extent of the epidemic since this is usually the time of the year when flu is prominent in the United Kingdom.

It is likewise almost sure that if the H1N1 outbreak disappears in the coming weeks, there might still be an outbreak of the virus in the autumn. If the situation indeed transforms into an epidemic, then 30% - 40% of the general population might become susceptible to infection. Professor Ferguson believes that any outbreak might become longer since the summer season in the United Kingdom is fast approaching.

On the other hand, Sir Liam Donaldson, who is concurrent Chief Medical Officer for England, believes that this new strain of H1N1 virus is something which people has natural immunity and has not received any vaccination yet. For this reason, one becomes susceptible to infection and spread to other people.
However, there is no sufficient information about the virus yet and H1N1 is still a subject of studies by major laboratories in the world. Once there is sufficient information about the virus, only then can it be possible to make improved predictions about individuals who are at higher risk and likely to have serious complications.

At present, the situation in Mexico is creating confusion and it is hard to make a firm a conclusion about what is likely to happen. In any case, there is a need to be ready for any untoward incidents that may happen.

Professor John Oxford, meanwhile, believes that the H1N1 outbreak is not as alarming as the H5N1 bird flu virus. He believes that the country can provide the basic H1N1 immunity for the population. The outbreaks outside of Mexico have not resulted to deaths which is an indication that the virus is not that aggressive.

Aside from that, the summer months is fast approaching so it is less probable for the H1N1 virus to cause an outbreak as well. In any case, the United Kingdom has enough antiviral medicines to treat half of the population.

With this in mind, there is no cause for worry about the H1N1 virus, as it appears that it would cause an outbreak that would be felt all over the world and increase mortality rates.

The outbreak of H1N1 began in Mexico City and as of today has resulted to the death of 42 people and more than 800 confirmed cases of swine flu infection. Although it has now spread in 22 countries, it is believed that this new virus outbreak would not be result to a pandemic and is milder than similar virus infections.

According to the World Health Organization, efforts for developing a swine flu vaccine has been ongoing since the first human case of the virus has been confirmed. Estimates place the initial doses of the vaccine will be administered in 5 to 6 months time.

While people diagnosed with H1N1 virus seems to be headed for recovery, there have been deaths recorded. Aside from that, receiving vaccines for this virus is important particularly the elderly and individuals with a weak immune system, since they are prone to complications such as pneumonia.

Likewise, the vaccine will serve as protection in case the condition persists particularly during the winter months which is the time when influenza is at its peak.

According to the World Health Organization (WHO), although they are still incomplete, current evidence shows that seasonal influenza vaccines will provide minimal or no protection against swine flu. Every year, a new batch of flu vaccine is developed and matched with strains that the WHO determines will most probably circulate in the winter months, which happens to be the peak season for influenza outbreaks.

Influenza virus comes in various strains which contains different proteins on their surfaces. The body's immune system can only fight and destroy a virus if they are able to recognize these proteins. It is worth noting that antibodies that recognize one strain may not detect other strains.
Existing vaccines may only offer some protection against swine influenza if the proteins on its surface are identical to strains used to develop previous vaccines. According to the NIBSC, they are trying to determine if the swine flu virus, which is an H1N1 strain of type A influenza, as well as previous H1N1 vaccines match current vaccines.

The preparation of a vaccine commences after a virus develops as they provide the starting point for the production of the vaccine. As such, there is always a time delay while a vaccine is being developed. Preparation of a vaccine involves several steps so it would take several months before a vaccine becomes available.

According to WHO estimates, the virus needed for producing the vaccine will be accessible to vaccine manufacturers by the middle of May while the initial dose for a new vaccine would be ready within 5 to 6 months after that. Waiting time would be much longer if the growth of the vaccine proceeds rapidly.

Vaccination plays a crucial role in the prevention and reduction of the effects of serious conditions. Unfortunately, they are not entirely effective and could lose its effectiveness if the virus mutates.
Existing flu vaccines are valid for about one year and are 70% - 80% effective against transmission with strains of influenza virus that are identical to strains used in the production of vaccines.

The WHO believes that it is too early to tell how the A(H1N1) virus would change. It is closely monitoring any changes in the virus and this would help countries quickly react to any important changes that the virus may show.

Vaccines help the body combat certain diseases in case an individual becomes afflicted with the illness in the future. On the other hand, an antiviral drug is used on people who is already infected with a virus. Although they work in various ways, they generally work to prevent the virus from spreading to different cells in the body.

Swine flu vaccines are administered prior to exposure to a virus so they would be protected from that agent. Antivirals only work if administered within a certain period of time before or after they are exposed to the virus.

Swine flu is an illness which derives its name from a virus that infects pigs. While the virus cannot affect people, they are likely to get an infection from time to time. The virus is communicable and can be transmitted from one person to another.

The symptoms of swine flu are like those manifested in a regular flu and may include cough, sore throat, body aches, headache, fever, chills and fatigue.

The H1N1 virus continues to become widespread in the United States. The Center for Disease Control believes that the number of cases, hospitalizations, and deaths will continue within the coming days and weeks.

The Center for Disease Control is aggressively responding to the growing outbreak. The objective of the agency is to curb the spread and severity of the illness as well as to inform health care providers, public health officials, and the general public to fend off the challenge by the medical crisis. Likewise, the CDC is giving interim guidance on a daily basis as a response to the rapidly growing crisis.

For treating swine flu, there are antiviral medicines that can be administered. So far, oseltamivir, amantadine, rimantadine, and zanamivir are the approved drugs for swine influenza treatment in the United States.
However, amantadine and rimantadine will not work against swine flu as the H1N1 virus was found to be resistant against these medicines. Laboratory procedures, on the other hand, have proven that H1N1 is susceptible to oseltavimir and zanavimir.

Using antiviral drugs in the treatment of swine influenza works by making your illness milder and making you feel relieved earlier than expected. Aside from that, antiviral medicines prevent the onset of serious complications.

Antiviral medicines are most effective when administered after the onset of the illness usually within a couple of days. However, it should be considered two days after the onset of symptoms, especially for hospitalized patients or those at greater risk for influenza-related complications.

Administration of anti viral drugs is also useful in preventing influenza when given to an individual who is not sick but has exposed to a person with swine influenza.

It can reduce the possibility of infection by 70% to 90%. The duration of intake will be determined by the condition of the patient. Currently, there are no accessible vaccines for protecting against H1N1.

In order to keep yourself from getting infected by the virus, here are some of the things that can be done:

- Keep yourself informed about H1N1. You can visit the official website of the World Health Organization or check brochures from local hospitals or medical facilities.
- Since the influenza virus can be transmitted from one person to another through coughing or sneezing, you can keep yourself busy by doing the following:

- When coughing or sneezing, cover your nose and mouth with a tissue. After using the tissue, dispose of it and throw it in the trash.
- Wash your hands with soap and water after coughing and sneezing. Use alcohol-based hand sanitizers whenever necessary.
- To prevent germs from spreading, refrain from touching your eyes, mouth, or nose.
- If you become ill, the CDC recommends that you avoid contact with other people at work or school so as not to infect them.
- Comply with public health advice concerning school closures, crowd avoidance, and social distancing efforts.

As far as swine flu is concerned, health authorities are doing everything they can to prevent the outbreak of another deadly virus.

With this new strain of influenza running around, properly called Type A H1N1 swine infl

uenza, but more popularly known as the swine flu, I think it would be nice to give people the 411 on the latest medical emergency that's got the world's attention.

Swine influenza came from pigs, hence the name, and pigs usually have regular outbreaks of this disease. The problem with it this time is that this strain of influenza has managed to jump the species and went over to us Homo sapiens and cased a bit of havoc.

Pigs don't have to worry about it because most of them have built-in resistances to the diseases, mostly because of the constant evolutionary exposure to the disease. They like us when we receive the flu: a few chills, sniffles and a bit of bed rest and we're right as rain. Problem with that is us humans don't have this resistance to swine flu, mostly because we're not pigs. The pigs would be in the same boat if a human strain had jumped into the porcine population.

The other problem with it is its virulence. The Center For Disease Control have determined that this strain of swine flu is contagious and can be passed to other people through the normal vectors: the virus can be transmitted when someone touches something that is contaminated and the puts it in his eyes, nose, or mout. It's even airborne as microscopic droplets can travel through the air when someone sneezes. The CDC, however, is still a bit hazy on some other factors like incubation time and much contact is too much contact.

Another problem is that the swine flu has the same symptoms as regular human flu, just worse by an order of magnitude. High fever, cough, sore throat, body aches, headaches, chills and fatigue can either mean you've been hit by the ordinary human flu and should take the usual cures or maybe you have the swine flu and need to go to the doctor immediately. Personally, it would be better to take no chances and just go to the doctor. Diarrhea and vomiting are the big warning signs though. Death by flue isn't direct though. It just compounds with other diseases like pneumonia and makes it even worse. It can also kick any existing medical conditions you have like asthma up a notch.

So, the question on your mind now probably is: is there no hope or should I just run to the hills to avoid human contact? Thankfully, you don't have to go that far. The CDC has recommended the use of several medicines to treat yourself with and to prevent the spread of the disease. Oseltamivir and zanamivir are viral inhibitors that make sure that the virus does not reproduce. More common antiviral drugs that are bought over the counter can also be effective. They make the symptoms milder and help your body heal itself faster. They can also stop some of the higher level complications that can happen when you are infected, if you take them early enough.

Of course, an ounce of prevention is better than a pound of cure. To avoid getting infected, try to avoid close contact with sick people and wash your hands on a regular basis, especially before you eat. If you have the unfrotunate luck of getting sick, isolate yourself and check your symptoms. Immediately consult with your doctor if your sickness persists more than usual.

The swine flu is just the latest in a long line of diseases that have endangered the human race. No matter how frightening it is, it's still pretty survivable. All you need to have is the right knowledge to win the battle.
