Facing criticism that the World Health Organization has been slow to respond to Zika, Dr. Margaret Chan delivers her first major address on the outbreak.
A team of researchers working on a Zika vaccine has a massive study underway assessing pregnant women and newborns in the northeastern region of Bahia, Brazil. It is the largest study of its kind into a virus that is sweeping across Latin America and has been linked to microcephaly in infants.
Some Latin American countries are calling on women to postpone getting pregnant. Women's rights activist Monica Roa thinks that's "naive and ineffective."
On a trial basis, a British company is releasing genetically modified mosquitoes in Brazil to try to reduce the Aedes aegypti population — the species spreading Zika.
Authorities in Colombia, Ecuador, El Salvador and Jamaica are encouraging women to delay getting pregnant due to the spread of the mosquito-borne illness, Zika. The virus has been linked to brain damage in infants. Delaying pregnancy is a challenge for women in the region where rape is the cause of many pregnancies, and women have little access to contraception.
For the fourth day in a row, protesters took to the streets of Haiti's capitol demanding the resignation of the current president. Elections were postponed this weekend, and the electoral crisis has turned into a constitutional one.
Haiti was supposed to hold a presidential election on Sunday. The head of Haiti's electoral council said he was delaying the vote for security reasons. Residents have taken to the streets to protest.
WHO says the virus is moving fast because the mosquito carrying Zika is widespread in the hemisphere, and the population is not immune. Only Canada is likely to be spared.
