West Nile Virus: A Threat to Be Reckoned With – Rising Cases Prompt Health Concerns.
A Closer Look at West Nile Virus
Table of Contents
West Nile virus, a mosquito-borne illness, has become increasingly prevalent in recent years. This year’s infection rates are approaching record levels, with 100 confirmed cases across nine regions of Greece. Of these, 76 individuals have developed serious neurological symptoms, including encephalitis and meningitis.
The virus primarily affects older adults, with the average age of fatalities being over 60. Sadly, 12 deaths have been reported thus far. For every case that impacts the central nervous system, an estimated 140 people may be infected with mild or no symptoms.
Climate change has exacerbated the situation, leading to year-round mosquito activity. Recent studies have even detected the virus in mosquitoes during winter months.
Common symptoms of West Nile virus include:
- Fever
- Headache
- Body aches
- Fatigue
- Rash
More severe cases may present with:
- High fever
- Neck stiffness
- Disorientation
- Tremors
- Muscle weakness
- Paralysis
Prevention is crucial in controlling the spread of West Nile virus. Key measures include:
- Using insect repellents containing DEET or picaridin
- Wearing long-sleeved shirts and trousers
- Eliminating standing water around homes
- Installing or repairing window screens
Diagnosis typically involves blood tests or analysis of spinal fluid. While there is no specific treatment for West Nile virus, severe cases may require hospitalisation for supportive care, including intravenous fluids.
Public health officials are urging caution, especially as the warm summer months continue. Those with underlying health conditions such as diabetes, cancer, or kidney disease may be at higher risk for complications.
Fresh West Nile Virus Fatalities Reported
The Greek health authorities have disclosed new West Nile virus cases and deaths. From 7-14 August, 21 additional infections were identified, bringing the total tally for 2024 to 76. Sadly, two more individuals succumbed to the virus, raising the death count to 12.
Those who died were over 60 years old, with a median age of 80. Notably, the Kallithea area in Attica registered its first case in three years.
A 2010 study suggests that for each central nervous system infection, roughly 140 people contract the virus with mild or no symptoms. It’s crucial to note that West Nile virus spreads via infected mosquito bites, not person-to-person contact.
Key Points:
- 21 new cases in one week
- 2 additional deaths
- 76 total cases in Greece for 2024
- 12 total deaths this year
- Median age of deceased: 80 years
- First Attica case in 3 years (Kallithea)
This information underscores the ongoing presence of West Nile virus in Greece and the importance of mosquito control measures.
