Aedes aegypti, the Zika-carrying mosquito.
The Zika outbreak that started in Brazil in 2015 continues on five continents, causing neurological disease and birth defects.

Zika is not gender neutral: women’s rights are at stake.

Aedes aegypti mosquito, which can spread dengue and Zika on February 4, 2016.
Emerging research suggests that preexisting immunity to dengue virus, which is endemic in South America, could make a subsequent Zika infection worse.
Most ill health can be avoided on family holidays through research and planning in advance, plus smart packing.
Simple steps can lower your risk of bringing home traveller's diarrhoea, respiratory infections and mosquito-borne diseases from your holiday.
Zika arrives in Brownsville, Texas.
There are likely to be more Zika cases reported in Texas.
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?

For viruses like dengue, being injected with the pathogen as in a vaccine can open the door to secondary infections.
Our immune system protects us but when it comes to some mosquito-borne disease, it can work against us. What are the implications for the development of a Zika virus vaccine?

It's hard to contain a mosquito-borne infection like Zika when the conditions are ideal for it to spread.
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.
Three researchers examine the big challenges of urban development: from city leadership to lock-ins.

Increasing isolation threatens global health. International cooperation is critical to fighting diseases that will not respect borders.

The long vaccine development process is focused on ensuring production of the safest and most effective vaccine for use.
The outbreak of Zika virus in Brazil had Australian travellers on alert but transmission is only possible in tropical Queensland.
New research shows common local mosquitoes aren’t able to spread Zika. This means Australia is unlikely to see a major outbreak of the disease. But a risk remains in northern Queensland.
County officials gear up to hand-spray mosquitoes in San Diego.
Congress has failed three times to approve spending to stop the spread of Zika. Their long-term response isn't much better.
Most cases of Zika are asymptomatic.

A computer model suggests that while more cases of Zika can be expected in the continental U.S. outbreaks will probably be small and are not projected to spread.

Politics, not epidemiology or medicine, drives government responses to disease. Politicians are the ultimate decision-makers in public health, and they must respond to political forces.
With more birth abnormalities linked to Zika, effects of the virus may be more sinister than we thought.
Arthrogryposis is where a baby's joints are deformed due to a shortening (known as contractures) of the muscles from before birth.
Researchers are trying to understand how maternal immune responses might contribute to certain neurological disorders in offspring.
A pregnant woman's immune response may be a risk factor for some neurological conditions like autism and schizophrenia in the baby later on.
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.
