The Phases of Swine Flu

A process that happens if two different types of influenza virus infected a single cell and it can produce a new strain of influenza is called re-assortment. It will act as a “mixing vessel” in which re-assortment can occur between flu viruses of several species such as pigs are prone to influenza viruses that can also infect both humans and birds. This is because if the virus allows pieces of RNA from different viruses to mix together and form a novel type of virus as a new virus particles are being assembled from a virus splitting between eight independent pieces of RNA.

On the other hand, the World Health Organization raised the pandemic alert level from phase four to phase five, signaling that a pandemic is “imminent”.

To know more about different phases of Swine Flu as defined by the WHO, I enlisted six of them” defined by the WHO:

If a virus circulated among animals but there are no reported cases of infections to humans will fall under phase one. An example of this phase is an outbreak of flu symptoms in your hog race backyard.
In phase two there is an identified animal flu virus and caused infections to human, and it will be considered a potential pandemic threat.

An example is when the owner either the child or an adult within the hog race backyard got infected with a flu from their animal symptoms.
Phase 3 specified that a confirmed animal or human-animal flu virus has caused small outbreaks in human race, but has not resulted in human-to-human transmission that is sufficient to sustain community-level outbreaks. An example in this phase is when a child within the hog race backyard got infected together with his father, his mother and his siblings.

Radically in Phase 4, there is a cause of community-level outbreaks of human-to-human transmission of an animal or human-animal flu virus. This phase will focus to contain the spreading of the virus. The United Nations will then inform different countries asking to advice their people such as traveling to containment areas. All countries with infected with the swine flu must also consider in deploying a pandemic vaccine. An example of this when the infected family member went out from their backyard decided to talk to his friends and unaware that hes spreading the virus.

In the 5th phase, if there are at least two countries in one region and spread the virus by means of human-to-human transmission. The signal of the pandemic is imminently strong. The infected countries are required to advise people with respiratory illnesses to stay home. There should be an advisory of suspension of classes. An example of this is when a man-infected virus either a family member or any of his friends travel to another neighboring country.

The sixth and final phase also called the pandemic phase. A pandemic phase is just like a spread of virus in phase 5 but extended at least one other country outside their geographic region. There must be an implementation of contingency plans of health systems in all levels. An example of this is when a man-infected virus travel to another continent.

Whatever phases of Swine Flu outbreak, we are experiencing in our country or geographic region we must prepare and prevent it to spread to lessen the death toll.

The Lowdown on The 2009 Swine Flu Outbreak

The 2009 outbreak of swine flu or H1N1 virus is recently hugging the limelight due to the potential harm or effects it can have on a patient or on a community. Unfortunately, the source of the virus still cannot be traced.

Before the first case in the United States was discovered, the illness was believed to have started in Mexico which eventually spread to other countries. Recently, the first case of swine flu was reported in
Costa Rica. Alarmed that it could grow into a worldwide flu epidemic, the World Health Organization of the United Nations and the Center for Disease Control Prevention (CDC) in the United States raised its pandemic alert level to Phase 5, which signifies that a “pandemic is imminent.”
While experts believed that the recent outbreak is not as fatal as previous epidemics, such as the SARS virus, health officials believe that the number of cases could go up as the new flu is expected to make its way throughout the United States.

The new swine influenza strain is apparently a new variant of four strains of influenza A virus subtype H1N1. According to the Center for Disease Control and Prevention, one of the strain is endemic in humans and birds and a couple are endemic in pigs.

However, according to scientists the 2009 H1N1 outbreak is of swine origin which is associated with the virus isolated in North America in 1998. To hasten understanding of the current outbreak as well as in coming up with a vaccine, scientists from Canada have completed the full genetic sequencing of the H1N1 virus.

The new strain of H1N1 has become widespread in Mexico and the United States with confirmed cases in 18 countries and suspected cases in 42 others. Travelers have been warned not to travel to affected countries such as Iceland, Singapore, Thailand, South Korea, Hong Kong, Singapore, to name a few.

In addition, warnings have also been issued warnings to visitors of countries affected by the outbreak. It is advisable for visitors to see the doctor right away if they experience flu-like symptoms.
In Mexico, schools, universities, and all public events were suspended from April 24 to May 6, 2009. In the United States, over 400 schools were closed as of May 3, 2009, which included schools in Texas and about 250,000 confirmed or probable cases.

Dr. Keiji Fukuda, who is the Assistant Director-General for Health Securiy and Environment of the World Health Organization confirmed that efforts to control the outbreak is already too late and should now focus on lessening the effects of the virus. He also clarified that closing borders or limiting travel to infected areas will do little in stopping the spread of the H1N1 virus.

On April 28, 2009, the Center for Disease Control and Prevention suggested that as much as possible, people should avoid non-important travel to Mexico.

According to Dr. Ira Longini, who is an expert in the mathematics and statistics of epidemics, staying at home, seeking medical care, closing public venues, and making anti-flu medicines accessible can help reduce the sickness by almost two-thirds.

Finally, according to Dr. Longini, the focus of efforts is to slow transmission until there is a vaccine that can be developed and made available for controlling swine flu outbreaks.

Tamiflu And Relenza Against Swine Flu

Newsbreak on the flash: A new strain of Swine Flu that has killed 149 and sickened nearly two thousand in Mexico has spread to the United States and is raising fears of a possible pandemic. Through this article you will learn more about the disease and why it is causing concern among health officials and inform the readers about the two suggested antiviral drugs by Centers for Disease Control and Prevention (CDC) to fight Swine Flu pandemics.

This prescription of antiviral medication that can be used to treat influenza infections between children and adults is called Tamiflu. If their symptoms have started within the last two days they are advice to start taking the Tamiflu. This antiviral medication can also be used to prevent children, teens and adults if they are exposed to the influenza virus.

Relenza (ruh-LENS-uh) is more active than the Tamiflu. This kind of medicine, aside from treatment of influenza they can also prevent the suspect to getting the flu again. While some antiviral medicines only protect against influenza A, Relenza is effective against both influenza A and B. This Relenza drug belongs to neuramidase inhibitors group of medicines. These medications target the influenza virus and prevent it from spreading inside your body.

Relenza treats the cause of influenza at its source, rather than simply treating the symptoms like the role of Tamiflu. Simulations suggest that if physicians choose a second effective antiviral such as zanamivir. Zanamivir is the generic name of Relenza as first-line treatment in even a few percent of cases, but can solve to delay the spread of resistant strains.

The available antiviral treatments for influenza, the virus is resistant to rimantadine and amantadine, but sensitive to the oseltamivir and zanamivir. Oseltamivir is the generic name Tamiflu. This strain may mutate develop resistance of oseltamivir in the future.

Tamiflu and Relenza is highly recommended by the CDC for both treatment and prevention of the new strain. 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 had already extended by the United States government and Roche Applied Science. Not only that, the other members of the G8 Countries extended their contract stockpiled of Tamiflu from vaccine manufacturers.

It is highly recommended not to buy from online pharmacies without an address of these two types of medications because their stockpiled are counterfeited. Consult to the World Health Organization for information about the antiviral drugs before making any steps in your country.

Medical experts warned the public not to take the antiviral drugs if you are not ill. You only want to be safe but the worst thing is if you take any of this antiviral drugs may lead you to a virus developing drug resistance. They suggest that antiviral drug should be taken only to very sick people or an individual with low immune system.

From the undetermined source that only one out of three Americans would get Swine Flu vaccine or antiviral drugs. So, it means the vaccine manufacturers especially the manufacturers of Tamiflu and Relenza have no enough capability to do more drugs against the pandemics.

According to CDC, testing has found that the Swine Flu virus remains at risk to two common antiviral drugs, Tamiflu and Relenza.

Swine Flu: The New Pandemic

Everyone’s all abuzz with panic nowadays it seems. That’s mostly because after SARS and bird flu, another new strain of virus has managed to rear its head. The H1N1 influenza virus, more popularly known as the swine flu, exploded on to the global scene last April via a large-scale infection in Mexico City.

I think everyone’s seen the images on CNN a thousand time. Surgical-masked Mexicans crowding the hospitals with worrisome shots of full hospital beds.The Center for Disease Control and the World Health Organization raised their alert levels in hopes of catching and cutting off the infection at the bud, but it seems that cases have been reported all over the world. It seems that the current fatalities from disease are from Mexico but everyone is just expecting for the other shoe to drop.

To understand all of this panic, ypou need to have a little background. Influenza, or more popularly known as the flu, is probably one of the most infectious diseases out there. Airborne and highly contagious, it could spread like wildfire all across the world. Now you’re asking what’s the matter with a few people getting a bit of sniffles? That’s because this isn’t your ordinary flu.

A lot of the flu viruses we are exposed to have been in the human system for hundreds of years. We’ve managed to build an immunity to these strains. The big problem that’s got everyone running scared is the idea that a flu strain has crossed species. This is what happened with the bird flu and now, with the swine flu. The pigs and birds have also built up resistances to these diseases, however, since humans are not used to them, these strains of flu have a very large potential of being fatal.

The last time a large-scale flu epidemic raged around the world, electricity was just coming into vogue and cars were all Model Ts. The Spanish Flu Epidemic of 1918 literally set the bar for every modern disease in terms of casualties. Fifty to a hundred million people worldwide died over a period of two years from 1918 to 1920 as the disease spread worldwide. Following on the heels of the Great War, it was a one-two punch that killed an entire generation of young men and women. What everyone’s afraid of is this: the 1918 epidemic was a subtype of the H1N1 flu virus, the same virus that seems to have crossed over and become a real threat to humans.

This is why the CDC is keeping a close watch on Mexico and hoping all of the subsidiary cases worldwide aren’t indications of the beginning of some worldwide epidemic. The good news about this is that the disease is treatable. Medicine and vaccine production alerts have been sent out by the CDC and most pharmaceutical companies have started churning out oseltamivir and zanamivir.

The problem with that is the demand may outstrip the supply depending on the swine flu’s virulence. More common antiviral drugs are also available but they’re not exactly definitive cures. They serve to weaken the symptoms and give you a fighting chance and prevent some of the worse flu symptoms like diarrhea and vomiting.

So as the world waits and watches the situation in Mexico, it would be a good idea to take a few precautions. Regular hand washes and vitamins can help make sure you avoid the initial infection of the swine flu. Avoiding pork’s not needed though. Swine flu can’t be transmitted through food. Remember to just a take a few preventive measures and you can come through clean and healthy.
