Water Went Inside My Nose While Swimming in Cenote: What's My Risk of Getting Naegleria Fowleri?

Naegleria fowleri is a rare but potentially fatal brain infection caused by a free-living amoeba that can be found in warm, freshwater environments, such as cenotes. When contaminated water enters the nose, the amoeba can travel to the brain and cause primary amebic meningoencephalitis (PAM), a severe inflammation of the brain and spinal cord.

Risk Factors

The risk of contracting Naegleria fowleri from swimming in cenotes is extremely low. However, certain factors can increase the risk, including:

  • Swimming with open sores or cuts
  • Diving or jumping into shallow water
  • Stirring up sediment at the bottom of the cenote

Symptoms

Symptoms of PAM typically appear within 1-12 days after exposure and can include:

  • Severe headache
  • Nausea and vomiting
  • Stiff neck
  • Seizures
  • Hallucinations

Treatment and Prevention

There is no specific cure for PAM, but prompt treatment with antibiotics may improve the chances of survival. Prevention is key, and the following measures can help reduce the risk of infection:

  • Avoid swimming in warm, freshwater environments if you have open sores or cuts.
  • Hold your nose closed when jumping or diving into shallow water.
  • Avoid stirring up sediment at the bottom of water bodies.
