Watch where people and animals interact

Our Expert Voices conversation on emerging diseases.

I always like to say, when predicting future disease outbreaks, what's past is prologue. More than 300 new diseases have emerged since 1940, and many of these have been the result of spillover from wild animal to human populations.

Zoonotic outbreaks are expected to increase as the buffer between humans and animals decreases and a disease can travel with humans from even the most remote region of the world to the other side of the globe within 24 hours.

We need better disease surveillance in human populations – especially those who are frequently in contact with wildlife. We should also be monitoring wildlife populations for changes such as die offs or major shifts in density or behavior that often precede zoonotic outbreaks in human populations.

Bottom line: We can't stop diseases from spilling over from animals to humans, but we can limit the extent of their spread and impact with good disease surveillance systems in place and the ability to rapidly respond. We must be ready to expect the unexpected.

Tech can't remember what to do in a down market

Wall Street's two-day-old coronavirus crash is a wakeup alarm for Silicon Valley.

The big picture: Tech has been booming for so long the industry barely remembers what a down market feels like — and most companies are ill-prepared for one.

Brace yourself for a coronavirus outbreak

Public-health officials’ warnings about the coronavirus are sounding increasingly urgent, with one top CDC official asking the public yesterday "to prepare for the expectation that this might be bad."

Reality check: Other administration officials, including President Trump himself, were more subdued in their assessments. But underneath those tonal differences, the reality of the coronavirus is the same: It spreads quickly, and has already spread to many countries, making it likely to start spreading here, too.

Exclusive: Pro-Trump group plans post-Super Tuesday blitz on Democrats

Pro-Trump super PAC America First Action is preparing to unleash a series of targeted, swing-state attacks on the Democrats most likely to face President Trump after Super Tuesday, people familiar with the group's plans tell me in an exclusive preview of its strategy.

The state of play: The group has been tracking favorable/unfavorable ratings in Florida, Georgia, Michigan, North Carolina, Ohio and Pennsylvania for 2020 candidates Joe Biden, Bernie Sanders, Elizabeth Warren, Pete Buttigieg and Michael Bloomberg — under the theory that if Trump wins each of these six states he would win re-election.
