For centuries, disease outbreaks have forced cities to transform physically and operationally in ways that ultimately benefited all residents going forward.
Countries aiming to flatten the coronavirus curve have one crucial aim: reduce the “effective reproduction number” of the virus to below 1. This means the spread is slowing, rather than accelerating.
Aerosols are the tiny particles of liquid and material that float around in our environment. When they come from an infected person, they may be a significant source of coronavirus transmission.
Cellphone data can show who coronavirus patients interacted with, which can help isolate infected people before they feel ill. But how digital contact tracing is implemented matters.
COVID-19 has a long incubation time, and testing can take days to get results. Don’t let continually rising case numbers make you give up on staying at home.
Exponential growth, such as in a viral epidemic, starts deceptively slowly, then quickly balloons. A mathematician explains the importance of early action and the costs of delay.
Predicting how a virus will spread — and its effects — relies on mathematically sound and accurate models that account for factors like weather patterns and human behaviour.
Universities and colleges around the world are closing. People are fleeing from cities. Some people are being forced to move but others must weigh the risks and ethical concerns of travel.
Some measures taken in China to contain the COVID-19 outbreak have raised concerns about patient privacy. As other countries bring in containment measures, will patient privacy be compromised?
From the neighborhood to the newsroom to the White House, nobody stays silent during a health emergency. These terms are often mixed up, and it matters who is using them and when.
In a health crisis, decisions about treatment and containment must be made quickly. It’s crucial those decisions be based on research evidence, but fast and easy access is not always available.
By providing users with pertinent and reliable disaster-related information, Twitter has the potential to reduce the impact of a disaster. So why aren’t public organizations using it properly?
