a 58-year-old man and a 64-year-old man.
The age distribution of patients hospitalized for a laboratory confirmed
New infection with Influenza A (H1N1) shows that these patients are mostly younger
than 65 years.
Most hospitalisations are of children aged 0 to 4 years.
In total, until November 4 included 611 patients in the hospital and 17
deceased patients.
In 62% of inpatients and 81% of the deceased
patients had underlying medical problems.
The number of patients with flu-like symptoms that are reported to the GP is the last
week increased.
The incidence of influenza-like illness (IAZ) in the last week
was 11.8 per 10,000 inhabitants.
In 32 of the 79 examined samples (40.5%) were New
Influenza A (H1N1) found. The incidence of pneumonia was 1.2 per 10,000 inhabitants.
Last week included 28 patients in Intensive Care. A total of 69 patients
included (were) in Intensive Care. Of these 42 patients had people
required mechanical ventilation and 65.7% of patients had an underlying disease.
In the
age distribution peaks are seen in the age groups 10 to 15 years and between 45 and 65
year.
96% of the National Influenza Center from week 28 studied influenza
viruses were of type A (H1N1) v.
In the Netherlands last week 1 New Influenza A (H1N1) virus found resistant
against oseltamivir.
Within the Nursing Infectious Diseases Surveillance Network (SNIV) No increase in the
incidence of influenza-like illness seen. There is no increase in pneumonia among
nursing home residents.
In the week ending on Wednesday, October 28, 2009 in the total mortality of CBS
not significantly increasing. The mortality by age for the younger
age groups no mortality increasing.
Conclusion: The number of people visiting the doctor for flu-like symptoms is
increased. On this basis can still be spoken of a mild
influenza epidemic in the Netherlands. The reported number of hospitalizations is back
doubled compared to last week. There are 7 people in the past week deceased
resulting from the New Influenza A (H1N1), including 5 with underlying medical problems.
