BPSU study - Severe microcephaly (SSM-UKI)

Surveillance of severe microcephaly in the UK and Ireland commenced in October 2017. This study will find out how many UK babies are born with microcephaly each year and how seriously this affects their health and developmental outcomes, including problems with hearing and vision. It will provide a better picture of the care and support these babies and their families currently receive.

About the study

Microcephaly describes a baby with a ‘small head’, who has experienced poor head growth before or after birth. Severe microcephaly is defined by the World Health Organization (WHO) as a head circumference more than three standard deviations below the mean for age and sex. This rare condition may be associated with abnormal brain structure or neurodevelopment, and with disability, although some babies will develop normally.

Many different causes of microcephaly have been described, including genetic disorders, exposure during pregnancy to environmental toxins, certain drugs, infection or malnutrition. Two important infections in the mother that may cause microcephaly are rubella (German measles) and Zika virus.
