Zika virus is a flavivirus, like dengue and yellow fever, spread predominantly from vector to human, by the Aedes species mosquitoes, particularly Aedes Aegypti.(1) The efficiency of spread by other Aedes species mosquitoes, especially the more widespread Aedes Albopictus, is uncertain.
It was first identified during mosquito surveillance in 1947... more

Genetic engineering of pathogens and synthetic genomics (the ability to create synthetic viruses) are a reality. Dual use research of concern (DURC), sometimes referred to as “gain of function research” (GOF) is research intended to benefit humankind, but which can also cause harm, either through laboratory accidents or deliberate release.(1) The controversy... more

Travel is the most important vector for spreading infectious diseases globally. In the 1918 pandemic of influenza, there was a delay of over a year in the pandemic reaching Australia, because sea-travel was the only route to the island continent.
The rate of international travel has increased exponentially over the past 70 years(1), with travel more... more

Vaccinology as a discipline has arisen from paediatrics, with a great wealth of expertise and champions in infant vaccination. Over time, more and more adult vaccines have become available, with influenza, pneumococcal, tetanus and most recently... more

In South Korea, the epidemic of MERS coronavirus has caused over 126 cases and 15 deaths, being the largest epidemic to date outside of the Kingdom of Saudi Arabia.(1) This is the first time since the infection emerged in humans in 2012 that a satellite epidemic... more

This past 2014 Australian summer university break saw me travelling thousands of miles from Sydney, to the United States of America (USA). I went to spend a much-needed Christmas holiday at the US, staying with my elder brother’s family of five, residing in Virgina. At the time of my travels, the weather was freezing cold, with falling snow painting every... more

It is a little over one year since the Ebola virus disease outbreak was officially declared in West Africa. There is now great hope that if the recent gains achieved are sustained, the epidemic would have been contained in Liberia, Sierra Leone and Guinea by the middle of 2015. With over 25 000 reported confirmed cases and over 10 000 reported deaths, the crisis... more

After decades as a neglected, poorly researched disease, the unprecedented 2014 Ebola epidemic resulted in acceleration of research into drugs and vaccines for Ebola. Early predictions were that the epidemic would not be controlled until June or July in 2015 at the earliest, so vaccine trials may have been planned under this assumption. Late in 2014, however, the... more

The outbreak of hepatitis A due to contaminated frozen berries in Australia in February 2015 has caused an outcry about food security and food labeling. Managing the risks of imported food, however, is only one aspect of prevention for hepatitis A, and another aspect, vaccination, has gone unnoticed.
Hepatitis A is a common cause of viral hepatitis, which... more
