The more researchers learn about the virus Zika, the more anxiety on the prevalence and consequences increases. The latest disturbing news comes from the Italian team doctors have reported an unusual case in a 32-year-old woman infected with the virus during their stay in the Dominican Republic earlier this spring. After returning to Italy in mid-April, she manifested the usual symptoms – fever, headache and muscle weakness. Later, however, she began to notice relatively mild but permanent change in memory and tangible problems with concentration.
After extensive tests, doctors confirmed the presence of Zika in the body of the patient, but detected the infection in the central nervous system and vagina, they preclude it comes to viruses such as dengue. The 32-year-old Italian woman has fully recovered, but the conclusion of the doctors is that the virus caused the sudden swelling of the brain or called. encephalitis during infection – a rare but alarming result which underlines the need for early diagnosis of Zika related neurological symptoms, experts are clear.
Is already well known to Zika causes severe consequences in the fetus in infected mother during the first trimester of pregnancy. In these cases, the virus is able to cause significant neurological damage that lead to many birth defects. These include microcephaly, deformation of joints, defects in vision and hearing. On the other hand, only 20% of adult patients with infection, do not exhibit any symptoms at all, while those which occur, they are limited to those of mild influenza-like illness. However, doctors already know that the virus can cause serious consequences in adult patients. Even after the initial manifestation of infection is cleared from the body with a small percentage of people likely of developing Guillain-Barré syndrome. This is an autoimmune disease that targets the peripheral nervous system and causes muscle weakness, tingling in the legs and even temporary paralysis.
In contrast to these cases, neurological symptoms in Italian patient are caused by the direct reach of the virus to the brain. This may be not so surprising, since the data of several clinical trials have shown that in some cases it is disclosed the possibility that the virus infects the brain and destroying brain cells. These findings raise questions about the possibility Zika not just transient infection in adults and that exposure in the brain can have a lasting impact on long-term memory or the risk of developing depression, experts note. The report on the case of 32-year-old Italian was published in the journal Emerging Infectious Diseases.
