Could anyone give me the real, not the media hyped numbers, the real numbers about the Mexico and the worldwide case? As I read at BBC, when they stated there was 20 dead, there was 200. Now there are 146, so should we multiply this number with 10?
The real numbers are surely not covering the reality.

I agree, from the reports I have been reading through this virus seems to cause the most severe condition in people in prime health.
The better your immune system the more severe the respiratory condition can be?
In fact in some of the cases that ended in death many were in prime health, between the ages of 20-50 years... And the intense immune system reaction caused inflammatory tissue reaction and the lungs to fill with mucous and fluids... An overreaction of the immune system?
For reasons not completely known, too many immune cells can be sent to the infection site. This happens when a particular type of molecule in the body, known as cytokines, activate the immune cells at the infection site and cause more immune cells to flood the site of infection. This propagates what is referred to as a cytokine storm where far too many immune cells are caught in an endless loop of calling more and more immune cells to fight the infection. The cytokine storm ends up inflaming the tissue surrounding the infection.
When the infection is in the lungs, severe inflammation caused by a cytokine storm can cause permanent lung damage. A prolonged cytokine storm will eventually shut down breathing altogether. Airducts get clogged and cells no longer properly absorb oxygen. This is what makes the cytokine storm so deadly in certain epidemic strains, such as bird flu. Even bronchitis, other varieties of influenza, pneumonia, sepsis and possibly rheumatoid arthritis are susceptible to triggering a cytokine storm.

Looks like they aren't going to so much raise it as revise the rating system. The jump between Level 3 and Level 4 is quite large and doesn't properly encompass what is actually happening. They need a level 3.5.
edit : Well, I guess I'm wrong! I still think that they need a level 3.5 though.

In Phase 2 an animal influenza virus circulating among domesticated or wild animals is known to have caused infection in humans, and is therefore considered a potential pandemic threat.
In Phase 3, an animal or human-animal influenza reassortant virus has caused sporadic cases or small clusters of disease in people, but has not resulted in human-to-human transmission sufficient to sustain community-level outbreaks. Limited human-to-human transmission may occur under some circumstances, for example, when there is close contact between an infected person and an unprotected caregiver. However, limited transmission under such restricted circumstances does not indicate that the virus has gained the level of transmissibility among humans necessary to cause a pandemic.
Phase 4 is characterized by verified human-to-human transmission of an animal or human-animal influenza reassortant virus able to cause “community-level outbreaks.” The ability to cause sustained disease outbreaks in a community marks a significant upwards shift in the risk for a pandemic. Any country that suspects or has verified such an event should urgently consult with WHO so that the situation can be jointly assessed and a decision made by the affected country if implementation of a rapid pandemic containment operation is warranted. Phase 4 indicates a significant increase in risk of a pandemic but does not necessarily mean that a pandemic is a forgone conclusion.
Phase 5 is characterized by human-to-human spread of the virus into at least two countries in one WHO region (Figure 4). While most countries will not be affected at this stage, the declaration of Phase 5 is a strong signal that a pandemic is imminent and that the time to finalize the organization, communication, and implementation of the planned mitigation measures is short.
Phase 6, the pandemic phase, is characterized by community level outbreaks in at least one other country in a different WHO region in addition to the criteria defined in Phase 5. Designation of this phase will indicate that a global pandemic is under way.
