They should start breastfeeding within one hour of birth, be exclusively breastfed for six months and have timely introduction of adequate, safe and properly fed complementary foods, while continuing breastfeeding up to two years of age or beyond. Infants fed with expressed breast-milk from mothers with suspected, probable or confirmed Zika virus infection or who reside in or have travelled to areas of ongoing Zika virus transmission should be fed according to normal infant feeding guidelines (strong recommendation, very-low certainty of evidence). Among infants (0–12 months) affected by complications associated with Zika virus infection, infant feeding practices should be modified (such as adjusting the environment, postural correction or thickening feeds) to achieve and maintain optimal possible infant growth and development (strong recommendation, very- low certainty of evidence). Mothers and caregivers of infants affected by complications associated with Zika virus (such as feeding difficulties) should receive skilled support from health-care workers to initiate and sustain optimal infant feeding practices

Prevention
The virus is spread by mosquitoes, making mosquito avoidance an important element to disease control. The CDC recommends that individuals:
Cover exposed skin by wearing long-sleeved shirts and long pants treated with permethrin. Use an insect repellent containing DEET, picaridin, oil of lemon eucalyptus (OLE), or ethyl butylacetylaminopropionate (IR3535)
Always follow product directions and reapply as directed
If you are also using sunscreen, apply sunscreen first, let it dry, then apply insect repellent
Follow package directions when applying repellent on children.
These abnormalities can lead to intellectual problems, seizures, vision problems, hearing problems, problems feeding and slow development.Whether the stage of pregnancy at which the mother becomes infected affects the risk to the fetus is not well understood, nor is whether other risk factors affect outcomes. One group has estimated the risk of a baby developing microcephaly at about 1% when the mother is infected during the first trimester, with the risk of developing microcephaly becoming uncertain beyond the first trimester. Affected babies might appear normal but actually have brain abnormalities; infection in newborns could also lead to brain damage. Cause
Reservoir
Zika virus is a mosquito-borne flavivirus closely related to the dengue and yellow fever viruses. While mosquitoes are the vector, the main reservoir species remains unknown, though serological evidence has been found in both West African monkeys and rodents. Transmission
Transmission is via the bite of mosquitoes from the genus Aedes, primarily Aedes aegypti in tropical regions. It has also been isolated from Ae. africanus, Ae. apicoargenteus, Ae. luteocephalus, Ae. albopictus, Ae. vittatus and Ae. furcifer. During the 2007 outbreak on Yap Island in the South Pacific, Aedes hensilli was the vector, while Aedes polynesiensis spread the virus in French Polynesia in 2013.Zika virus can also spread by sexual transmission from infected men to their partners. Zika virus has been isolated from semen samples, with one person having 100,000 times more virus in semen than blood or urine, two weeks after being infected.
