A fifth person has died in the Netherlands after contracting the West Nile virus, while confirmed human infections have risen to 44, according to recent figures from the Rijksinstituut voor Volksgezondheid en Milieu (RIVM).
Fifth Fatality Reported as Dutch West Nile Cases Climb to 44
Sixteen New Notifications Over the Past Week
The RIVM received 16 new notifications over the past week regarding individuals diagnosed with the West Nile virus. This brings the total number of established human infections in the country this year to 44.
In most instances, patients were diagnosed after seeking medical care and being admitted to a hospital with symptoms.
Interpreting Fatalities and Transmission Vectors
While five individuals who tested positive for the virus have died this year, the RIVM notes that a positive test result does not automatically mean the virus served as the direct cause of death.
The pathogen is transmitted to humans exclusively through the bites of infected mosquitoes.
Asymptomatic Majority and Mild Flu Syndrome
The vast majority of people who contract the West Nile virus experience no symptoms at all. According to public health data, approximately 80 percent of infected individuals remain entirely asymptomatic.
For the 20 percent who do develop clinical signs, the infection typically manifests as a mild flu syndrome. Symptoms commonly include:
- Fever
- Headaches
- Fatigue
Neurological Complications and Vulnerable Populations
In rare instances—affecting fewer than one percent of cases—the disease progresses to a severe form involving neurological complications.
Public health data indicates that older adults and individuals with weakened immune systems face a substantially higher risk of experiencing a severe course of illness.
