The United States .- More children have been diagnosed with a mystically paralyzing disease in recent weeks, and health authorities in the United States said they are still not sure about the cause.
This year's bill can outweigh the same outbreaks recorded in 2014 and 2016, officials said. Fortunately, the disease is still rare: 90 cases have been registered in 27 states, according to the Centers for Disease Control and Prevention (CDC).
It is still unknown which causes some children to lose the ability to move their face, neck, back, arms or legs. Symptoms usually occur approximately one week after the child has a fever or respiratory disease.
Health authorities refer to the condition as acute weak myelitis. No one has died of the disease this year, but CDC officials say at least half of patients do not recover from paralysis and some suffer from serious complications.
The Polio and West Nile virus were discarded. Doctors suspect that the cause may be some type of enterovirus, which in most people causes cold symptoms. But CDC officials say it is not yet clear.
The first wave of mysterious cases of paralysis in 2014 coincided with a widespread increase of diseases related to an enterovirus called EV-D68, reported CDC officials. But there were no such increases in the 2016 outbreak or in the present.
There is also a lack of clinical evidence: The CDC authorities have examined the cerebrospinal fluid in about 75% of the 90 patients and have discovered the presence of EV-68 in a single case. Another type of enterovirus, known as EV-A71, was found in another patient.
