The fertility-inhibiting effect of mosquitoes: Socio-economic differences in response to the Zika crisis in Colombia

The buzz on babies: the fertility-depressing effect of the zika virus in Brazil

“…More directly related to our research, Gamboa and Lesmes (2019) In the Brazilian summer of February 2016 -one nine-month full-term pregnancy period following the peak in searches for Zika -there was a sizeable drop in the number of births in Brazil. Figure 3 illustrates this trajectory.…”

“…As well, this is an increase of around 2% to 4%. In context, the Zika virus epidemic that threatened with a terrible disease for newborns (microcephaly) in urban areas of the country in 2016, reduced birth rates in 10% (Gamboa and Lesmes, 2019).…”

Mosquitoes, birth rates and regional spillovers: Evidence from the Zika epidemic in Brazil

“…By using this information, we prevent our estimates from being affected by a short‐term migration. Following Gamboa and Lesmes (2019), we defined a municipality as affected by Zika if they reported at least one case of Zika infection to the Ministry of Health. This measure considers all cases notified to the Ministry of Health (confirmed and probable cases, without confirmation).…”

“…Faced with this reality, the population is expected to respond to the risks and recommendations of the Ministry of Health, possibly by increasing care and/or reducing the number of births. Some studies have analysed the population's response to the epidemic and have found a negative effect of the Zika/microcephaly on fertility rates in Brazil (Castro, Han, Carvalho, Victora, & França, 2018; Junior & Rasul, 2019; Quintana‐Domeque, Carvalho, & de Oliveira, 2018; Rangel, Nobles, & Hamoudi, 2019; Ryu, 2019) and on birth rates in Colombia (Gamboa & Lesmes, 2019). However, although there is an extensive literature that shows the spatial dependence on the incidence of viral outbreaks such as dengue and Zika (Cai, Ding, Yang, Peng, & Wang, 2019; Fitzgibbon, Morgan, & Webb, 2017; Flórez‐Lozano et al, 2020; Martínez‐Bello, López‐Quílez, & Torres Prieto, 2018; Mondini & Chiaravalloti‐Neto, 2008), issues related to spatial interaction are not addressed in studies that sought to analyse the impact of Zika incidence on birth rates.…”
