Thank you very much for posting this.

I wish every country in the world would copy the report system of Sweden :tiphat:, and/or that WHO would create a central database, based on a system like Sweden´s, where every country could fill in their H1N1 info dayly/weekly, and that the database was acesseble for everyone to read.

This is the best I can do, I cant get the graphic scheme to be in place like in the original website.

Information for healthcare and laboratories - epidemiology and clinical symptoms

Summary of available information on the epidemiology and clinical symptoms. The new influenza A (H1N1) has not previously been identified either in humans or any other species. Available information suggests that it is a virus originating in North American swine influenza that circulated on the continent in about 10 years. The lack of historical data and genetic information on influenza strains in pigs limit the ability to accurately comment on the new influenza origin.
Incubation period

Variable data; 1-5 days (Spain), 4-6 days (UK), 2-7 days (USA).
Reproductive rate, R0

(The average number of persons becoming infected by an infected person during the time he / she carries the infection.)
Estimated at 1.4 (1.3-1.8) in Mexico. (Seasonal flu is estimated to be about 1.3.)
(Source: Secretar?a de Salud, Mexico.)
Other estimates (Euro Surveill. 2009; 14 (19)):

• Bo?lle et al. R0 = 2.2-3.1
• Fraser et al. R0 = 1.4-1.6
• Rambaut et al. R0 = 1.16
• Nishiura et al. R0 = 2.3 (Euro Surveill. 2009; 14 (22))

Attack rates

(Cumulative incidence = number of exposed people who become infected divided by the total number exposed.)
3.5/100 000 in Mexico (Source: Secretar?a de Salud, Mexico)
Age

Data from Mexico (June 25, 2009) (n = 9028). (Source: Secretar?a de Salud, Mexico.)

For these, the median age of 27.5 years (27 days - 89?r), 70% women and 65% hispanica. 19 of 30 (64%) had underlying disease or were pregnant. Of the five women who were pregnant 2 developed complications, spontaneous abortion and premature hinnbristning. None of the 30 hospitals treated patients showed signs of secondary bacterial infection.
On May 11 had been 98 cases reported in Spain. The median age was 22 (14-55). Of these, 78% visited Mexico.10% had received the vaccine against seasonal influenza.
On May 11, 65 cases confirmed in Britain. 58% of cases were aged 10-29 years. None of the infected had received influenza vaccine.
Data from studies in the EU / EFTA countries (June 8, 2009) (Eurosurveillance)
93% of all cases with information on symptoms (n = 371) had at least one symptom. 8% of cases were asymptomatic. Asymptomatic cases were significantly more common in the age group <20 years compared with older cases. Gastrointestinal symptoms were significantly more common in the age group <20 years compared with older cases.
Complications were seen in 7 of 286 cases (2%): pneumonia (4), otitis (1), elevated liver enzymes (1) and need for therapy with sterioder (1).
20 of 260 cases (8%) received the vaccine against seasonal influenza for the benefit of the season.
105 of 291 cases (36%) hospitals, but in several countries, this was done by isolation reasons rather than the illness was serious.
Underlying diseases in hospital treated patients in New York (June 12, 2009) (n = 567) (WHO) Of 567 hospital treated cases were 80% at least one risk factor for serious illness.
The most common were:
Asthma 41%
Pregnancy: 28% of all hospital treated women of childbearing age (n = 142)
Age <2 years: 12%
Diabetes: 11%
Immunodepression: 9%
