I will try to post update on H1N1 news on and off since this is of big concern by most people now.
Latest update by WHO on H1N1:
Worldwide, the majority of patients infected with the pandemic virus continue to experience mild symptoms and recover fully within a week, even in the absence of any medical treatment. Monitoring of viruses from multiple outbreaks has detected no evidence of change in the ability of the virus to spread or to cause severe illness.
In addition to the enhanced risk documented in pregnant women, groups at increased risk of severe or fatal illness include people with underlying medical conditions, most notably chronic lung disease (including asthma), cardiovascular disease, diabetes, and immunosuppression. Some preliminary studies suggest that obesity, and especially extreme obesity, may be a risk factor for more severe disease.
This is the latest from European Centre of Disease Control (ECDC):
- There are no reports as yet of unusual presentations or transmission routes for this influenza compared to normal seasonal influenza viruses. There is no indication of risk of infection through food or potable drinks.
- If the pandemic behaves like previous ones, cumulative clinical attack rates over the first major wave of infection in 2009–10 might be expected to be in the range of 20% to 30%, with a reasonable planning assumption of 30%.
- Based on experience in North America, clinical attack rates will be highest in children and younger adults.
- Adults over 60 years seem, at present, to be the least affected age group, though there are indications from the USA that those few that are affected experience the highest risk of severe disease of any age group.
- The groups experiencing most of the severe disease and death are those in the risk groups of people with chronic underlying medical conditions (this includes morbid obesity), pregnant women and young children (especially under two years of age).
- Most of those infected experience a mild self-limiting illness, even in people in risk groups. However, as for seasonal influenza there are some people who experience more severe disease and some of these die despite medical care. These include a few people without any known underlying condition and outside other risk groups.
One risk facing us is that our health resources may be stressed to the limits, as was the experience in New York city, and that other lethat diseases like Dengue may be neglected in our preoccupation with H1N1. Dengue kills more people in Malaysia than most seasonal flu every year, so while we should be vigilant about H1n1, we should not let our guard down against Dengue.
