PART 1: Zika virus spread by mosquito bites and sex P1
Health information websites announced that Zika virus appeared in 2015 in Brazil, the Caribbean islands and the Latin American countries. This is an important emerging disease and horrible health issues today because it causes infant deformities. Zika virus disease currently does not has specific treatment and even preventive vaccine, follow affirmation of government health website.
US officials declared a travel warning for pregnant women, who are pregnant should not travel to 22 countries and regions in Latin America, including El Salvador, Bolivia, Brazil, Colombia, French Guiana France, Ecuador, Guatemala, Guyana, Panama, Honduras, Mexico, Paraguay, Venezuela, Suriname, and the Caribbean region: St. Martin, Barbados, Puerto Rico, Guadeloupe, Haiti, Martinique.

In addition, there are a number of points as Cape Verde, off the west coast of Africa, Samoa in the South Pacific.
What should know:
What is Zika virus?
A type of virus which was first discovered in monkeys in Uganda in 1947, the name of this virus is named after the forest where it first time is detected. Virus originated mainly from African tropics.
The incubation period of Zika disease is about 2-12 days after being bitten by mosquitoes. Approximately 75-80% of patients infected with the virus Zika do not have any clinical manifestations. Patients only have mild disease manifestations. Patients often fall to sick with mild fever (37.8 to 38.5°C), fatigue, growing maculopapular rash on the skin, painful in small joints of hands and feet, congestive inflammation, myalgia, headache, orbital pain, and asthenia.
A few patients may have abdominal pain, nausea, diarrhea, mucosal ulceration or itching. Need appointed monitor fetal ultrasound for pregnant women who has Zika virus suspected to be able to detect small head fetal complications.
Aedes strains which can cause Zika virus transmission including A. africanus, A. aegypti, A. vitattus, A. furcifer, A. Apicoargenteus and A. luteocephalus. When mosquitoes bite people or animals who or which have Zika virus infection, the virus will multiply in the mosquito and after 10 days of incubation can cause transmit the virus to other people or animals. An infected mosquito individual can transmit virus for generations to mosquito offspring.
In addition to mosquitoes which is the main transmitted road, there are many other possible routes of transmission Zika virus such as transmission from mother to fetus, transmitted through sex. this virus RNA has also been detected in the blood, urine, semen, cerebrospinal fluid, amniotic fluid and breast milk of Zika infected patients.
What defects in infants
Researchs in 35 children with small head in Brazil, skull CT and transcranial ultrasound was detected calcified condition spread in the brain. Approximately 1/3 of the event of abnormal cell migration upset the brain structures as smooth brain syndrome (lissencephaly) or hypertrophic roll brain syndrome (pachygyria). Ventricular dilatation secondary caused by cortical atrophy or subcortical structures are also common.
Some children with congenital limited joint mobility (arthrogryposis) due to motor neuron shortcoming. Congenital retinal atrophy was also observed in children with small head neonatal malformations. These defects may appear when this virus infected mother during any quarter of pregnancy.
– There is no vaccine for preventing this virus. Prevention is mainly by preventing not to entering Zika epidemic areas. The individuals in the epidemic areas apply mosquito bites restrictive measures such as: Wear long clothes, bright colors, use insect repellant drugs, bed nets …
– In the affected areas to implement mosquito measures such as: keeping clean environment, removal of standing water supplies, sealed the jars, tanks or release mosquitoes killed fish, using trap…
– Need to use a condom when having sex with this virus infected person.
– Despite this virus RNA detected in milk but there is no evidence of transmission of Zika virus through breastfeeding so should not have recommended abstinence during breastfeeding mother suspected or identified this virus infection.
