Summary
Türkiye reported a significant rise in West Nile Virus (WNV) cases in 2024, with 133 infections and 13 deaths, primarily in Istanbul. Enhanced surveillance and a One Health approach are recommended for future prevention and control of this mosquito-borne illness.
Area of Science:
- Public Health
- Infectious Diseases
- Epidemiology
Background:
- Human West Nile Virus (WNV) infections have been reported in Türkiye since 2010, with annual outbreaks.
- Enhanced surveillance for WNV has been active since 2011.
- Early detection of WNV is critical for patient management and outbreak control.
Purpose of the Study:
- To evaluate the increase in WNV cases in Türkiye in 2024.
- To analyze the characteristics of WNV cases reported in 2024.
Main Methods:
- Retrospective analysis of confirmed WNV cases from January 1 to December 31, 2024.
- Data sourced from the web-based Infectious Disease Surveillance and Early Warning System and Laboratory Information Management System.
- Inclusion of all registered WNV cases in individuals.
Main Results:
- A significant increase in WNV cases was observed in 2024 after a four-year period (2020-2023) with no reported cases.
- 133 cases and 13 deaths were reported between July and October 2024.
- The majority of patients (58.6%) had West Nile Neuroinvasive Disease (WNND), with a mean age of 60.4 years; 72.2% were male. Most cases (47.4%) resided in Istanbul.
Conclusions:
- Clinician awareness and improved laboratory diagnostic capacity are essential for rapid WNV detection.
- Integrating human WNV surveillance with vector, animal, and transplantation surveillance is recommended.
- Adopting a One Health approach is crucial for effective WNV surveillance, prevention, and control.

01:28Infectious Diseases and Their Occurrence
97
Infectious diseases appear in populations through various transmission patterns, influenced by pathogen characteristics, population immunity, environmental conditions, and social behavior. Understanding these patterns is essential for effective public health surveillance and intervention. These categories—sporadic, outbreak, epidemic, pandemic, and endemic—help frame the nature and scope of disease events.Sporadic diseases occur irregularly and infrequently, without a predictable...

01:25Arboviral Encephalitis
70
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

01:27Influenza
101
Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

01:19Encephalitis l: Introduction
27
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

01:26Encephalitis ll: Pathophysiology
30
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
