2016, the year that was: Health + Medicine

Health spent a lot of time in the spotlight in 2016. Medicare was a major issue in Australia’s federal election and numerous government reviews into health were announced and reported.

Explainer: what are antibodies and why are viruses like dengue worse the second time?

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?

Pitting mozzies against mozzies to stop the spread of disease

Upscaling the success of emerging mosquito control technologies relies on automating the rearing and release of millions of mosquitoes. Australia is to become the testing ground for a novel strategy.

Zika and Ebola had a much worse effect on women: we need more research to address this in future

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.

Why a Zika vaccine is a long way off

The long vaccine development process is focused on ensuring production of the safest and most effective vaccine for use.

Common Australian mosquitoes can’t spread Zika

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.

How Congress is failing on Zika

Congress has failed three times to approve spending to stop the spread of Zika. Their long-term response isn’t much better.

Zika virus: Only a few small outbreaks likely to occur in the continental US

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.

US response to Zika: Fragmented and uneven

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.

I’m an OB-GYN treating women with Zika: This is what it’s like

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.

In Zika, echoes of US rubella outbreak of 1964-65

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.

Is the end of Zika nigh? How populations develop immunity

During a disease outbreak, lots of people can become infected in a short time and develop immunity, making it hard for the pathogen to spread.

What will it take to reduce infections in the hospital?

Thousands of people acquire infections while hospitalized. Many are caused by urinary catheters, a routine part of a hospital stay. But cutting back on their usage can lower infection rates.
Is a Zika vaccine being tested ahead of vaccines for other flaviviruses because Zika’s occurring in the context of an international sporting competition? Christian Bruna/AAP

News of Zika vaccine might be reassuring, but it’s too late for Rio, and do we really need it anyway?

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.
