WHO’s Zika app aims to provide essential information on Zika virus disease and its potential complications. Designed primarily for health care workers and responders, the app can also be a source of real-time information for the general public.
Download and use the app on IOS or android and have easy-to-use information at your fingertips. Access WHO’s technical guidance and other useful resources, follow ongoing Zika related-research and development, stay updated about the latest news, and follow the international response to Zika. New content, including trainings will be added to the app in weeks to come.
"Fight Zika": using animation to spread the word
WHO supports governments and response agencies to communicate the risk from the Zika virus disease and its suspected complications to their citizens and visitors. In collaboration with Scientific Animators Without Borders (SAWBO), WHO has produced this "Fight Zika" video focusing on controlling the Aedes mosquito which transmits Zika as well as deadly diseases such as chikungunya, dengue and yellow fever.
More language versions will follow for use in more than 60 countries currently affected by the outbreak of Zika.
Microcephaly is a rare condition when the head size is smaller when compared with other babies of the same sex, gestational or postnatal age. It can occur when the brain is affected either in utero or in infancy. It can be associated with intellectual and physical disabilities.
Measuring the head circumference of all newborns after birth is a key step in screening. Follow up for assessing neurologic development and detection of associated problems such as seizures, vision and hearing problems is necessary.
5 February 2016 -- WHO declared a Public Health Emergency of International Concern on 1 February after a substantial spike in cases of microcephaly and Guillain-Barré syndrome in the Americas. These cases are strongly suspected to be linked to Zika virus, a mosquito transmitted disease that has spread to more than 25 countries and territories in the region. This page links all WHO information to its response on this Public Health Emergency of International Concern.
- Microcephaly can be caused by a variety of factors, including infections in the womb, perinatal asphyxia, and genetic causes.
- Babies born with microcephaly are at risk for intellectual disability and may also develop convulsions and suffer physical disabilities as they grow older.
- There are no specific tests to determine if a baby will be born with microcephaly, but ultrasound scans late in the second trimester or in the third trimester of pregnancy can sometimes identify the problem.
- The most reliable way to assess whether a baby has microcephaly is to accurately measure head circumference 24 hours after birth, compare the value with WHO growth standards, and continue to measure the rate of head growth in early infancy.
- There is no specific treatment for microcephaly.
