The public in Sierra Leone was proactive in reporting suspected Ebola cases.
The power to overcoming Ebola was in public awareness by performing simple yet basic infection prevention and control measures like washing hands, isolation and reporting suspected cases.
Statistics and probability can sometimes yield mind bending results.
Sometimes statistics and probability can produce unexpected or counter-intuitive results. If we're hoping to use numbers to make good decisions, we should be wary of the traps.
A hospital nurse checks the temperature of all visitors in Conakry (Guinea) in 2014, at the height of the Ebola epidemic.
One year after the end of the West African Ebola epidemic, a study of survivors in Guinea shows what has been learned about the deadly virus, and what remains unknown.
What if it wasn’t back to the drawing board every year for a new flu shot?
Flu virus mutates so quickly that one year's vaccine won't work on the next year's common strains. But a new way to create vaccines, called 'rational design,' might pave the way for more lasting solutions.
We propose a different way to look at the factors behind chronic disease, like obesity and diabetes.
A new way of looking at what's behind chronic disease takes into account social, environmental and other factors, rather than blaming individuals.
IQ decline is highest among those who started using during adolescence and among the most persistent (daily) users.
After almost four-and-a half decades and from modest beginnings, the Dunedin study has evolved into one of the most significant long-term tracking studies in the world.
A pickup truck from the Department of Health fumigates in San Juan, Jan. 27, 2016.
It's hard to contain a mosquito-borne infection like Zika when the conditions are ideal for it to spread.
Alcohol use is traditionally higher among men than women but new evidence suggests this is changing.
Women are catching up to men in rates of alcohol consumption and this has important implications for how we think about our community response to harmful alcohol use.
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.
What could we do if a real-life zombie disease started to spread?
Patients and companions at the Cholera Treatment Center in Haiti, April 2015.

Unless drinking water and sanitation infrastructure are improved, cholera could remain in Haiti indefinitely.
Observational scientists study subjects in real life, outside a controlled laboratory environment.
The randomised controlled trial is touted as the gold standard in medical research. But its controlled laboratory conditions are far removed from the messy realities of life.
Elementary school students about 13 miles from the Fukushima Daiichi nuclear power plant walk past a geiger counter in 2012.
Remediation will never get radiation to zero in the area affected by the 2011 meltdown at the Fukushima-Daiichi nuclear power plant. Rather than safety, the conversation should focus on acceptable risk.
Even talking to a colleague at an academic conference overseas could have harsh ramifications.
Researchers face stiff fines or even jail time if they inadvertently communicate with foreign colleagues about matters deemed to have a military use.

French farms have seen a major outbreak of bluetongue virus, which can be fatal for sheep.
NASA’s Aqua satellite, carrying sensors used by researchers to measure mosquito-favoring environmental conditions on Earth.
Satellite imaging can locate mosquito-friendly environments, allowing us to predict the advance of diseases they carry.
Polio vaccinators carry boxes of polio vaccine drops as they head to the areas they have been appointed to administer the vaccine, in Karachi October 21 2014.
Researchers are piloting a smartphone app to collect better information about who is getting vaccinated and to design better incentives for health workers on vaccination drives.
The effects of alcohol vary considerably between different people.

The relationship between alcohol and violence is complex, and dramatic changes to criminal laws to punish intoxicated offenders are often ineffective, unfair or both.
Don’t stay up too late.

How does one prove that shift work causes breast cancer, as the authors of the new study claim? A cancer epidemiologist explains how scientists weigh evidence to figure out what causes cancer.
Try to predict the outcome of a single coin toss and you’ll have only a 50-50 chance of being correct.
Predicting infectious disease outbreaks is a tricky task to begin with. And it's made harder still by the fact that any individual outcome is subject to unpredictable – or stochastic – effects.
