imrsSince last summer, public-health officials have been trying to figure out why more than 100 children in dozens of states have suffered from a polio-like weakness in their limbs. And while authorities have not found a direct link to the severe respiratory illness that affected children across the country last year, they are exploring whether that nationwide outbreak may be tied to this mysterious situation. There have been 103 confirmed reports of children who have developed the illness, which is called “acute flaccid myelitis,” according to the Centers for Disease Control and Prevention. These cases, which span 34 states, have almost all led to the hospitalization of the affected children, with some of them put on breathing machines. Last fall, the CDC began testing cases that occurred after Aug. 1. They had tested 88 cases by mid-November and found some possible trends, but the ultimate cause of the illnesses were still unclear. A handful of cases involved children who had been affected by the enterovirus D68 outbreak, but the CDC cautioned that no causal relationship between the illness could be confirmed by that time. There are also other viruses that can cause illnesses with symptoms like the ones currently being seen, the CDC noted. More
