- 36. Mesures preventives Quan tossiu o esternudeu cobriu-vos la boca i el nas amb un mocador de paper. Si no teniu mocador, tossiu o esternudeu a la part superior de la màniga. Ventileu sovint els espais tancats obrint les finestres. Quedeu-vos a casa si creieu que esteu malalts i truqueu a Si us faciliten una mascareta, poseu-vos-la. Eviteu el contacte proper amb persones malaltes de la grip, i no compartiu menjar ni estris i altres objectes sense netejar-los degudament. Feu servir mocadors de paper per netejar-vos el nas. Llenceu-los al cubell de les escombraries o a la paperera. Netegeu-vos les mans després de tossir o esternudar amb aigua i sabó o amb un preparat a base d'alcohol. No us toqueu els ulls ni el nas amb les mans brutes.

Editor's Notes
- What are pandemics? Pandemics are when a new influenza A emerges to which most or many of the population have no immunity. The result usually from an animal influenza combining some of its genes with a human influenza. To be a pandemic strain an influenza A virus needs to have three or four characteristics. They need to be able to infect humans, to cause disease in humans and to spread from human to human quite easily. An additional criteria that is often applied is that many or most of the population should be non-immune to the new virus. Note this animated slide was first developed by the National Institute of Infectious Disease in Japan and we are grateful to them and especially Masato Tashiro for letting us use it.
- But remember this is idealised – and in 2009 in North America this is not putting as many people into Hospital as you would expect from the above. In the 2009 pandemic it is not clear yet what percentage are asymptomatic. Two reasonable estimates are 33% and 50% of the total infected. [ Note to Uwe – can you increase the asymptomatic fraction in both to make them look about 33% of the total ]
- This slide speaks for itself. The last line refers to some reserve plans which countries have which if enacted would be an over-response.
- Presently (May-June 2009) Europe seems to be in a prolonged initiation phase with occasional outbreaks and small peaks. This could go on for months with the real first wave coming in the autumn or winter. The pandemic waves will occur at different dates in different countries. And even within one country it will not affect every area at once
- This slide the original of which was developed by the United States CDC illustrates the theoretical aims of community mitigation by public health measures, mass use of antivirals etc. However it needs to be appreciated that the effectiveness of PHM is by no means certain. A further discussion of this can be found through the ECDC PHM ‘Menu’ http://ecdc.europa.eu/en/Health_Topics/Pandemic_Influenza/phm.aspx
