infectious disease

Just as antibiotics have bred resistance in bacteria, vaccines can potentially lose their effectiveness over diseases they controlled. Researchers are working to head off the evolution of new threats.

The long, variable times that some diseases incubate after infection defies simple explanation. An idealized model of tumor growth offers a statistical solution.

Simple math shows how widespread vaccination can disrupt the exponential spread of disease and prevent epidemics.

If you didn’t get a flu shot, you are endangering more than just your own health. Calculations of herd immunity against common diseases don’t make exceptions.

Mathematical insights into how RNA helps viruses pull together their protein shells could guide future studies of viral behavior and function.

The computational immunologist Purvesh Khatri embraces messy data as a way to capture the messiness of disease. As a result, he’s making elusive genomic discoveries.

A virus that causes crippling birth defects has been shown to do something else: It changes thousands of messages coming from DNA that control normal cellular activities.

The infamous case of Typhoid Mary underscores the importance of tolerance in understanding disease.

Scientists have developed new ways to forecast who will bounce back from disease by studying not just the way the immune system fights infections, but how the body repairs itself.
