Swine influenza - update 5
29 April 2009 -- The situation continues to evolve rapidly. As of 18:00 GMT, 29 April 2009, nine countries have officially reported 148 cases of swine influenza A/H1N1 infection. The United States Government has reported 91 laboratory confirmed human cases, with one death. Mexico has reported 26 confirmed human cases of infection including seven deaths.
The following countries have reported laboratory confirmed cases with no deaths - Austria (1), Canada (13), Germany (3), Israel (2), New Zealand (3), Spain (4) and the United Kingdom (5).
Further information on the situation will be available on the WHO website on a regular basis.
WHO advises no restriction of regular travel or closure of borders. It is considered prudent for people who are ill to delay international travel and for people developing symptoms following international travel to seek medical attention, in line with guidance from national authorities.
There is also no risk of infection from this virus from consumption of well-cooked pork and pork products. Individuals are advised to wash hands thoroughly with soap and water on a regular basis and should seek medical attention if they develop any symptoms of influenza-like illness.

Based on assessment of all available information, and following several expert consultations, I have decided to raise the current level of influenza pandemic alert from phase 4 to phase 5.
Influenza pandemics must be taken seriously precisely because of their capacity to spread rapidly to every country in the world.
On the positive side, the world is better prepared for an influenza pandemic than at any time in history.
Preparedness measures undertaken because of the threat from H5N1 avian influenza were an investment, and we are now benefitting from this investment.
For the first time in history, we can track the evolution of a pandemic in real-time.
I thank countries who are making the results of their investigations publicly available. This helps us understand the disease.
I am impressed by the work being done by affected countries as they deal with the current outbreaks.
I also want to thank the governments of the USA and Canada for their support to WHO, and to Mexico.
Let me remind you. New diseases are, by definition, poorly understood. Influenza viruses are notorious for their rapid mutation and unpredictable behaviour.
WHO and health authorities in affected countries will not have all the answers immediately, but we will get them.
WHO will be tracking the pandemic at the epidemiological, clinical, and virological levels.
The results of these ongoing assessments will be issued as public health advice, and made publicly available.
All countries should immediately activate their pandemic preparedness plans. Countries should remain on high alert for unusual outbreaks of influenza-like illness and severe pneumonia.
At this stage, effective and essential measures include heightened surveillance, early detection and treatment of cases, and infection control in all health facilities.
This change to a higher phase of alert is a signal to governments, to ministries of health and other ministries, to the pharmaceutical industry and the business community that certain actions should now be undertaken with increased urgency, and at an accelerated pace.
I have reached out to donor countries, to UNITAID, to the GAVI Alliance, the World Bank and others to mobilize resources.
I have reached out to companies manufacturing antiviral drugs to assess capacity and all options for ramping up production.
I have also reached out to influenza vaccine manufacturers that can contribute to the production of a pandemic vaccine.
The biggest question, right now, is this: how severe will the pandemic be, especially now at the start?
It is possible that the full clinical spectrum of this disease goes from mild illness to severe disease. We need to continue to monitor the evolution of the situation to get the specific information and data we need to answer this question.
From past experience, we also know that influenza may cause mild disease in affluent countries, but more severe disease, with higher mortality, in developing countries.
No matter what the situation is, the international community should treat this as a window of opportunity to ramp up preparedness and response.
Above all, this is an opportunity for global solidarity as we look for responses and solutions that benefit all countries, all of humanity. After all, it really is all of humanity that is under threat during a pandemic.
As I have said, we do not have all the answers right now, but we will get them.
Thank you.
