Spraying pesticides in Gama, Brazil, 2016.
A new study shows that the pesticide pyriproxyfen – widely used in Brazil during the Zika outbreak of 2015 – could disrupt thyroid hormones and thus affect brain development in children.
Researchers studying Alzheimer’s disease use fetal tissue for their experiments.
The Trump administration has banned NIH researchers from using fetal tissue. The tissue is an essential tool for scientists investigating diseases ranging from Alzheimer’s to Zika virus infections.
The World Health Organisation has pledged a long-term response to controlling the Zika virus because the threat is far from over
Finding Zika’s roots can help contain the virus.
The 2015 Zika outbreak in South America brought the virus to global attention. But tracing the history of the virus in West Africa can give clues to tackling future outbreaks.

Zika is not gender neutral: women’s rights are at stake.
How will the downgrade of Zika’s emergency status affect women like this 23-year-old Vietnamese woman and her baby born with microcephaly?

The World Health Organisation no longer sees Zika as a health emergency. But what does this downgrade mean for the health of mothers and babies?

Pregnant women in Sierra Leone, Guinea and Liberia were faced with the double fear of dying from Ebola as well during childbirth.
We found that less than 1% of published research papers around the time of both outbreaks, that related to the outbreaks, actually explored their gendered impact.
Talking with patients who’ve had Zika is tough.

Physicians like me are learning about Zika along with our patients. This takes a dose of humility on our part and an understanding from our patients that we learn something new every single day.

Though separated by time and place, there are surprising similarities in the the social issues raised by the rubella outbreak of 1964-65 and the recent Zika outbreak in South America.

The chance the someone at the Rio games will import the virus to their home country is low.
Is a Zika vaccine being tested ahead of vaccines for other flaviviruses because Zika’s occurring in the context of an international sporting competition?
Recently two events concerning the Zika epidemic coincided: two potential vaccines against the virus were declared a success when used in mice, and Jason Day withdrew from the Olympic Games.
Academics have sent an open letter to the World Health Organisation calling for the Olympics to be postponed or moved because of the Zika threat. They’re overreacting.

To tackle Zika and other viral outbreaks, we need to focus not only on the pathology of the disease, but also on the global political and economic architecture.
A new arrival in Australian backyards may increase the risks of mosquito-borne disease outbreaks.
Zika virus may be in the headlines but the burden of other mosquito-borne diseases, such as dengue fever, should not be overlooked.
Could fear of Zika loosen Latin America’s strict abortion laws?
Better access to birth control and safe, legal abortions in Latin America could save lives. But carving out Zika-related exceptions in existing restrictions might not go far enough to achieve this.
Even if Zika sometimes causes pregnant mothers to have babies with microcephaly, this does not necessarily mean every infected mother would have an affected baby.
Despite all the hype around Zika, crucial questions remain unanswered. How great is the risk that infection during pregnancy would result in a baby with microcephaly? And what can be done to prevent this?
Guilherme Soares Amorim, who was born with microcephaly, has his head measured.
Zika virus and microcephaly are firmly linked, but scientists are still trying to prove that it has caused the condition.
The link between Zika and microcephaly is not proven, but the incidence of both have greatly increased in the same areas.
Despite high rates of infection, the Zika outbreak would not have been particularly alarming had it not been for the sudden and – apparently associated – increase in the numbers of infants born with microcephaly.
