Experts are concerned that a microbe that rarely but sometimes finds its way into the human brain moves from its natural range in the south to the north. Once in the brain, the amoeba destroys brain tissue and causes inflammation and swelling. Amoeba is found naturally in warm freshwater, but with increasing temperatures it is found in the north-central and western states more than in the past.
A new study Amoeba is set to release in January on emerging epidemics that could expand its geographical range. The authors observed primary amoebic meningoencephalitis (PAM) cases caused by amoeba nuclea foliar between 1978 and 2018. It enters the brain through the nose and Swallowing does not cause infection. However, PAM is very rare, with only 34 cases in the last 10 years Centers for Disease Control and Prevention (CDC).
Amoeba can be found in water and prefers temperatures as high as 113 Fahrenheit, which is why experts believe it could be linked to its widespread northern climate change. According to their estimates, the study found that there was an increase in air temperature two weeks prior to exposure, and that adaptation to increased recreational activities in the water affected the spread of the amoeba and an increase in PAM events.

PAM is generally dangerous. The most recent cases Jackson Lake In Texas, six years old The boy was injured Died from it, and In Florida There was a 13-year-old boy infected. But there may be hope that it is not always dangerous There is at least one case There it was treated with antibiotics.
The researchers found that the maximum latitude for PAM cases moves about 8.2 miles north each year of the study. Fortunately, according to the study, the number of PAM cases does not seem to be increasing. “Our results further investigate the PAM’s recommended northward expansion and its possible association with higher temperatures,” the authors write.
But if the amoeba continues to spread in more waters in the north, it will lead to more cases. “If the water in the northern states continues to be hot, there is concern that people in those states could be at greater risk of drowning,” said CDC epidemiologist Jonathan Yoder. Inside.
