Sequencing the whole genome of patient virus samples lets scientists watch for new variants.

By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.
The hepatitis C virus has become extremely genetically diverse.
Direct-acting antivirals have mostly been used in countries with high incomes. These drugs would be effective against most hepatitis C strains. which are primarily low-income countries.
Sequencing the genetic code of virus samples taken from COVID-19 patients reveals how SARS-CoV-2 is spreading and changing.
The US lags in testing coronavirus samples from COVID-19 patients, which can help track the spread of the virus and the emergence of new variants. But labs are ramping up this crucial surveillance.

Ebola seems to be able to lay dormant in people for many years before causing disease again.

Cuba's access to internationally produced vaccines was nearly impossible due to the U.S. blockade. Its decision to make its own vaccines stands to pay off handsomely.

Shoring up surveillance and response systems and learning lessons from how the COVID-19 pandemic unfolded will help the world be ready the next time around.
Wouldn’t it be nice if one shot could protect you for life?

You need a new shot every year because current flu vaccines provide limited and temporary protection. But researchers' new strategy could mean a one-and-done influenza vaccine is on the way.
Vaccine hesitancy is a growing public health problem.

Vaccine hesitancy has resulted in multiple vaccine-preventable disease outbreaks. Research on vaccine hesitancy in South Africa is limited. But growing evidence suggests that it's becoming a problem.
Moose, a mixed-breed dog from the Nebraska Humane Society, trains in odor-detection work.
Scientists are experimenting with using dogs to sniff out people infected with COVID-19. But dogs aren't the only animals with a nose for disease.
Fauci is an accomplished scientist who also excels at connecting with the public.

Fauci turns 80 this Dec. 24 – and he's been on the national stage for decades. Here's more about his work before COVID-19 and why he was perfectly poised to help the US respond to the pandemic.

A fast-moving equine flu cratered the US economy in the fall of 1872, showing all too clearly that horses were essential and deserved better treatment.
A substantial proportion of people may refuse or delay taking a COVID-19 vaccine.
Combating social media disinformation regarding vaccines is critical to reversing the growth in vaccine hesitancy around the world.
Airline health advice has so far mostly focused on staying hydrated and avoiding deep vein thrombosis. What passengers really want, however, is free hand masks, hand sanitiser and more space between passengers.

The WHO has been criticised for being slow to recognise the scale of the COVID-9 pandemic. We suggest a new protocol on infectious diseases to help with faster data collection and more open sharing.

To better anticipate and manage the emergence of new pandemics, a paradigm shift is needed to take into account the complex interactions between human health, animal health, the environment and the economy.
