Zika virus is derived from the flavivirus family (i.e., virus transmitted by ticks and mosquitoes). It provokes the same name of a fever.
transmission path
Tract infection with Zeke few:
- by mosquitoes of the genus Aedes - do not occur in Russia:
- sexual contact with a patient. Unlike, for example, HIV, Zika virus generated a full immunity, however convalescents not contagious;
- transplatsentarno - from an infected mother to the fetus.
What is the danger of the virus Zika
The possibility of transmission of the virus through the placenta gave rise to an increase in panic that the disease causes microcephaly in the fetus, but it is not yet clear.
Note: mikroentsefaliya - an excessive reduction in size of the head in relation to other parts of the body, developed normally. The disease is not curable and is accompanied by mental failure of different severity. Mikroentsefaliya - rare pathology that occurs with a frequency of 0, 012% (1 in 8000).
Important! Isolated cases of abnormalities in fetal development is really found in South America among tribes endemic Zika fever, but it has not yet established whether the cause of the virus, inbreeding or any other disease.
However, research is still carried out and it is possible that a dangerous virus to the fetus effect is still confirmed.
Zika virus, long time being endemic in remote areas of Africa, is now spreading all over the place for tropical areas where the Aedes mosquito lives:
- Central Africa;
- Central and South America;
- India;
- part of Southeast Asia, including Indonesia.
Symptoms of fever Zika
The incubation period is 3-7 days.
For Zika fever is characterized by the "standard" for the common cold symptoms, which complements the rash.
Most often the disease develops in the following sequence of symptoms:
- fever;
- blotchy rash on the body and limbs, which begins from the face and neck;
- headache;
- migrating joint pain;
- conjunctivitis.
Zika fever symptoms similar to dengue fever, leptospirosissome malaria, Typhus, measles and a number of tropical diseases.
Diagnostics
Patient during the acute phase of the disease is necessary to donate blood.
Diagnosis is performed by PCR.
Zika fever treatment
Since the disease is not a bacterial etiology, that it is not treated with antibiotics, specific antiviral therapy also does not exist yet.
However, the disease is relatively easy, and after recovering formed proof lifelong immunity.
Zika fever treated symptomatically:
- can be used for removal of heat or aches in the body, e.g., acetaminophen;
- It shows excessive drinking;
- rest.
Recover within 5-7 days. Mortality from Zika fever is very low.
prevention
How Not to Die:
- while in the tropics, to use drugs and mosquito antikomarinymi setkamii avoid night walks and mosquitoes Areas (swamps, tall grass, bushes);
- because during the fever in 60% of cases are asymptomatic, in any case not to have sex for 10 days with people who have arrived from endemic areas;
- avoid direct contact with the monkeys (to take them in his arms, not feed).
It is also desirable to refrain from visiting Brazil for the first three months of pregnancy - it is there at the moment (. February 2016) recorded the rapid spread of Zika fever.
