Pathogenesis, diagnostic challenges and treatment of zika virus disease in resource-limited settings.

The association of Zika virus (ZIKV) infection with congenital malformation and neurological sequelae has brought significant global concern. Consequently, the World Health Organization (WHO) declared it "a public health emergency of International concern" on 1 February, 2016. A critical review of its pathogenesis would lead to a better understanding of the clinical features and the neurological complications.

Low Zika virus seroprevalence among pregnant women in North Central Nigeria, 2016.

Background: Zika virus (ZIKV) has been known for decades in Africa but contemporary data is lacking at large.

Objectives: To describe the seroepidemiology of ZIKV in North Central Nigeria.

Assessment of the vitamin B12 status of pregnant women in Nigeria using plasma holotranscobalamin.

Maternal vitamin B12 deficiency during pregnancy is an independent risk factor for neural tube defects and other neurological problems in infants. We determined the vitamin B12 status of 143 pregnant women in Nigeria representing all trimesters who presented to an antenatal clinic in Jos, Nigeria, using holotranscobalamin II levels (holoTCII), which is a measure of the vitamin B12 that is available for uptake into tissues. The holoTCII concentration ranged from 13 to 128 pmol/L.
