Given the cases of the mysterious disease that has reached Bahia and Ceará, states that border Pernambuco, the State Health Department (SES) has issued an alert to medical units. They should notify and investigate within 24 hours any cases that present with extreme muscle pain, renal failure and black urine, as well as similar clinical features.
So far, two people have died on suspicion of contracting the disease in Bahia. Another 53, including patients from Ceará, reported similar symptoms: muscular pains that begin in the neck and radiate to the rest of the body, in addition to dark urine.
"The State Department of Health of Pernambuco states that it has remained alert regarding the occurrence of suspected cases of acute myalgia to be clarified in some states of the Northeast. Through the Network of Strategic Information Centers in Health Surveillance (CIEVS Network), SES-PE follows and maintains a network of state care and surveillance services updated on the evolution of these events," the department says in a note.
Brazilian and American researchers try to unravel the mystery.
However, four laboratories in Brazil and one in the United States still have no prediction of when they will have the answers. They do not know when they will complete the blood samples that were collected.
The suspicion that the disease is caused by a fish toxin found in the Bahian North Coast is already ruled out. However, one of the main assumptions is that the contamination originates from a virus found in sewage in the feces: a virus of the hepatitis A family.
Parechovirus was found in the last analysis carried out in the laboratory of the Health Sciences Institute of the Federal University of Bahia. However, what intrigues the researchers is that there are no reports of deaths related to this virus. Generally, the patient is hospitalized, but without risk of death.
