What is Naegleria fowleri?
Naegleria fowleri is a rare but deadly amoeba known as the 'brain-eating amoeba.' It thrives in warm freshwater environments like lakes, hot springs, and ponds. The amoeba enters the body through the nose, travels to the brain, and causes a severe brain infection called primary amoebic meningoencephalitis, which is often fatal.

What is West Nile virus?
West Nile virus is a mosquito-borne virus that can cause illness in humans. It is transmitted through the bite of infected mosquitoes, which become carriers after feeding on infected birds. Most people infected with West Nile virus experience mild symptoms or no symptoms at all, but some can develop serious neurological conditions.
-
Why are these infections increasing now?
Both Naegleria fowleri and West Nile virus cases are rising due to environmental changes, including warmer temperatures and increased rainfall. These conditions create ideal habitats for the amoeba and mosquitoes, expanding their reach and increasing the risk of infection in different regions.
-
How can I protect myself from amoeba and West Nile?
To avoid Naegleria fowleri, avoid swimming in warm freshwater bodies, especially during hot weather, and do not submerge your head in untreated water. For West Nile virus, use insect repellent, wear long sleeves and pants outdoors, and eliminate standing water around your home to reduce mosquito breeding sites.
-
Are climate changes causing more outbreaks?
Yes, climate change is contributing to the increase in outbreaks of both Naegleria fowleri and West Nile virus. Rising temperatures and changing rainfall patterns expand the habitats of these pathogens and their vectors, leading to more frequent and widespread infections globally.
