The AES epidemic attains a peak every year in May-June in almost 236 villages of Muzaffarpur, killing innocent children; it disappears in the monsoons, only to re-surface the following year. In 2014, almost 800 children suffered from AES, with a mortality rate of 150.
According to some doctors, children affected with AES die mainly because of unbalanced blood sugar levels. But the root cause is yet to be identified. Experts say that after inducing glucose to the patient, sugar levels go up to 100 but drop down in no time. Doctors say that the children can be saved only if blood sugar level is maintained. Incidentally, this disease is affecting only the poor children, the ones already struggling against malnutrition and poverty. Despite several researchers trying to solve the mystery behind this epidemic, the reasons still remain unknown.
