The West Nile virus seems to spread rapidly in our country. The 2 patients who died were over 78 years old, had been severely ill, presenting events from the Central Nervous System (CNS).
On the week of August 13-20, 2025, 12 patients were diagnosed with the virus. Thus, the total number of domestic cases (including dead) this year reached 47. Of these patients, these patients, only 6 had mild symptoms.
Everyone else had CNS events (including the brain and spinal cord) and most importantly:
- Encephalitis or
- Aseptic meningitis or
- Meningoencephalitis
All patients so far needed hospitalization. The two of them, as mentioned above, lost their lives. Others 34 have been dischargedwhile the rest 11 are still hospitalized. Of these, 2 are hospitalized in an intensive care unit (ICU).
