You have probably heard a lot about the term “phase” of the pandemic alert issued by the World Health Organization lately. But, do you know the actual meaning of it and the definition associated with each phase? Perhaps you may have asked questions such as

l The actual number of phases in the pandemic influenza warning
l The meaning of each phase in the pandemic influenza warning

As defined by the World Health Organization, there are 6 phases following by “Post Peak” and “Post Pandemic” respectively.

Generally speaking, phases 1 to 3 indicate that the pandemic is predominantly animal infections and there are few human infections.

Up one level is Phase 4 indicating that the situation has become worsen, sustaining that the virus can transmit from human to human causing community level outbreaks.

Phases 5 to 6 indicate that there will be widespread of the virus with multiple human infections. Phase 6 indicates that the situation is very serious and a world-wide pandemic is under way. On the other hand, a strong signal of a pandemic is imminent when the warning of phase 5 is issued.

Post-peak period means that although there appears to be a decrease of pandemic activities, there is a possibility of recurrent events and a second wave may be coming.

In Post-pandemic period, the influenza disease becomes seasonal and the virus will return at a specific season. Surveillance of the virus is of utmost important.

Escalation of the Swine Influenza Pandemic

The continuation of the spreading of the swine flu in the United States following by the first case of death of a 2-year old boy who had recently visited Mexico prompting President Barack Obama to call the outbreak of swine flu a “serious situation” which required the “utmost precautions”.

In view of the development, an urgent meeting was held again by the World Health Organization in Geneva to discuss the seriousness of the current situation. After evaluating the data and latest development around the world, Dr. Margaret Chan, WHO’s Director-General has raised the current level of influenza pandemic alert from phase 4 to 5, indicating that every country in the world should remain high alert and detect any unusual cases of influenza-like illness and pneumonia immediately as the H1N1 virus could have the capacity to spread through each country quickly in addition to possessing the ability to mutate rapidly.

As of April 30, 2009, the effect of swine flu has been mild in the United States while comparing with the situation in Mexico, where swine flu had killed more than 150 people and sickening over 2,000. There were 91 cases of laboratory confirmed cases, 1 in Arizona, 14 in California, 1 in Indiana, 2 in Kansas, 2 in Massachusetts, 2 in Michigan, 1 in Nevada, 51 in New York, 1 in Ohio and 16 in Texas including 1 death. As the swine flu virus is relatively new and many people do not have immunity to the virus, medical professionals expect that the H1N1 virus will continue to spread with more cases of deaths in the coming weeks.

How can we stay away from the Swine Flu Virus?

Although swine influenza is highly contagious, there are certain procedures that you can take to keep yourselves away from the virus. At this time, it is best for everyone to go trough a little trouble to ensure the safety of others. For example, it is advised that you should

What is Swine Influenza?

Swine Influenza (swine flu) is a highly contagious respiratory disease of pigs caused by type A influenza. The swine influenza virus (SIV) is very common in pigs and can cause outbreaks of influenza during the cool seasons usually in fall and winter. However, SIV is not common in humans. On the other hand, if people work in a place where they need to have a close contact with swine, they are at a high risk to get infected if the virus carries a strain which can infect human. Furthermore, the SIV can mutate into a different form which can transmit from human to human. The outbreak of swine flu in 2009 was an exact situation which was the mutation of the swine flu virus and the result could be multiple human infections. Also, evidence indicated that swine flu virus could be transmitted from the patients to health care workers who had close contact with them.

Swine Influenza – The Latest

The updated information indicated that the Swine flu has become worse and an urgent which was the second meeting was held by the Emergency Committee of the World Health Organization on April 27, 2009 to discuss the latest situation.

The Director-General had raised the level of influenza pandemic alert from phase 3 to 4 indicating that the situation has become worsened and the disease would sustain human to human transmission, meaning that everyone in the world including the uninfected areas should be high alert of the situation and taking every necessary precaution to protect oneself from the swine flu virus because the likelihood of a pandemic has increased.

It was also noted that international travelers must take extra precaution when travelling to the United States, Canada and especially Mexico where the swine influenza A (H1N1) virus was originated. As of April 27, 2009, it was reported that the suspected death toll from swine flu escalating to 149 people and close to 2,000 people have been hospitalized with serious cases of pneumonia in Mexico. While the number was indeed shocking, one would be equally shocking to hear that the actual number of confirmed cases of swine flu was still unknown by the Government of Mexico. As of April 27, 2009, it was reported that there were 18 laboratory confirmed cases of swine flu virus in Mexico.

Giving the rising death toll, the government of Mexico is now urging for the decision to close all schools nationwide and restricts large gatherings in the public which will further damage the already gloomy economy in Mexico.
Nevertheless, international travelers are warned by each individual country at this time not to travel to Mexico unless it is absolutely necessary as some expect that the worst is yet to come.
