How quickly does PAM infection progress?

Primary amoebic meningoencephalitis (PAM) is a serious infection of the brain caused by a tiny organism called Naegleria fowleri. This infection is very fast-moving. Symptoms usually start within 1 to 9 days after the amoeba enters the body through the nose. These symptoms can include headache, fever, nausea, or vomiting.

After symptoms begin, the disease progresses rapidly. Advanced symptoms can develop quickly, such as a stiff neck, confusion, seizures, and even hallucinations. The infection usually leads to severe brain damage and is often fatal.

Due to the rapid progression of the disease, early detection and treatment are crucial. Unfortunately, PAM is often diagnosed late because its initial symptoms can be mistaken for more common illnesses. Prevention is important, and avoiding warm freshwater sources where the amoeba is found can reduce risk.

Understanding the speed and severity of PAM can help in seeking timely medical attention if exposure is suspected.
