The W.H.O. raised the world influenza pandemic alert to level 4, the last level before declaring a pandemic. At the same time the WHO state that it is no longer possible to contain and reduce world wide spread of the infection. The change to a higher phase of pandemic alert indicates that the likelihood of a pandemic has increased, but not that a pandemic is inevitable.

ProMED state that: 
Analysis of previous pandemics show that transmission in the Northern hemisphere stops in the beginning of May. The best analysis is made by Viboud et al. (JID 2005;192:233-48). Even if the present A/H1N1 has pandemic potential it is therefore highly likely that the outbreak will fade out within the next 2 to 3 weeks, but it will reappear in the autumn on the northern hemisphere. The second wave can be more pathogenic than the first wave, and inclusion of the present virus in the vaccine for the autumn therefore should have the highest priority

Comment of influenza A/H1N1 (swine flu) 
The spread has now reached such a level that travels to Mexico should be restricted to absolutely unavoidable visits and visitors should bring Tamiflu or Relenza with them for standby emergency treatment. Other countries (see the BBC link above) start to impose screening for arriving passengers with influenza like illness, which means that international travel now starts to be affected by the outbreak.
