The obesity epidemic, the flu epidemic, the opioid epidemic... in the 21st century, everything seems to be an "epidemic". But what does the term actually mean?
People and animals live side by side – and can have pathogens in common.
No one then knew a virus caused the 1918 flu pandemic, much less that animals can be a reservoir for human illnesses. Now virus ecology research and surveillance are key for public health efforts.

With many men 'missing' from the population in the aftermath of the 1918 flu, women stepped into public roles that hadn't previously been open to them.

Science has come a long way in the 100 years since the worst flu pandemic in history. But that doesn't mean that the country is ready for another health disaster.
Despite new findings, the deaths can't be blamed on enteric fever alone.
Approximately 80 percent of all pharmaceuticals used by Americans are produced overseas.
Thanks to Hurricane Maria, some US hospitals are experiencing a saline shortage. In times of emergency, medical supply chains break down too easily.

Don't believe these 10 common myths about the 1918 Spanish flu.
Bats are the only mammals capable of true flight. Scientists believe flight may influence their immune responses to coronoviruses, which cause fatal diseases such as SARS and MERS in humans.
Scientific studies show that bats may carry "coronoviruses" causing SARS and MERS - without showing symptoms of disease. Could the bat immune system be key to human survival in future pandemics?
Every year in Canada, there is an average of 23,000 cases of lab-confirmed influenza, 12,000 people who need to be admitted to hospital and 3,500 flu deaths.
As influenza season begins in North America, many people wonder whether to get a flu shot. Our expert delves into the pros and cons of the vaccine and how it works.
Vaccines for the flu offer mediocre coverage compared with those for other diseases.
A better vaccine could have reduced the rates of flu, but not the high-dose Fluzone vaccine doctors were touting at the start of the week.
John Gerrard says a developed city like Sydney could not cope with an epidemic of the scale of the recent Ebola outbreak.

This antivirus software protects health, not computers. Researchers are beginning to combat deadly infections using computer-generated antiviral proteins – a valuable tool to fight a future pandemic.
When a man was diagnosed with Ebola in Dallas in 2014, workers cleared out the apartment unit where he had been staying.
President Trump wants to slash global health funding at a time when more investment is needed, not less. This spending can protect Americans – as well as foreigners – from deadly diseases.

Malaria has long menaced the world, but gains have occurred. Those efforts could now be stymied by budget cuts, however. Here's how a disease that knows no borders could widen its deadly reach.

After the Spanish flu we didn’t see any new flu strains for forty years. Now novel strains are increasingly popping up.
How is it the flu has managed to stay around for so long, and why haven't we beaten it yet?
When governments delay releasing information about disease outbreaks, algorithms come to the rescue.
