In the Earth’s interconnected ecosystem, humans are interlopers. We’re far outnumbered by viruses alone, not to mention all other animal species. But this fact was largely ignored by most people outside of infectious diseases until 2020, when “coronavirus” became a household word and a microbe killed over 6.5 million people—and counting.

Nearly every country has experienced how a virus from a different part of the world can devastate families, lead to food shortages, eliminate jobs and completely transform normal life. Viruses have our attention, and that can lead to important changes, building on this wider understanding. However, it will take a shift in scientific priorities and long-term commitment.

Some may wonder why one should bother with this while we’re struggling with the “cleanup” of this global disaster. The answer is immediate and critical, safeguarding human health. About 60% of infectious diseases

It might sound far-fetched, but this kind of animal–human encounter is now commonplace as cities expand into areas that were once uninhabited by humans. The global trade in exotic pets

Since the way we live could produce more pandemic viruses,

Preventing Surprises

A universal alarm

Unlike the headline-grabbing breakthroughs in cancer research, a disease many people have experienced, it can be difficult to see the connection between a virus identified in the tropics and our daily lives. The most recent pandemic and the rush to develop a vaccine made the connection obvious.

We can avoid being surprised again if we adopt a holistic approach to developing this essential body of information.

One Health,

We can work to stop pandemics before they take place, so we will have the science and systems necessary to replicate that success all over the world. This will take time and money, which will only become a priority if we see the value of the successes already realized.

Lessons Learned (and Ignored)

The study of smallpox, transmitted among humans, and development of a vaccine showed it’s possible to prevent a devastating disease. The value of this research proved itself with the recent outbreak of mpox.

Vaccines, the result of fundamental research, have saved millions of human lives over time.

But lack of funding for early-stage research means we’re missing critical information. In the case of mpox, we still don’t know which animal is the original source of the virus.

Global awareness is having a positive impact. The World Health Organization renamed monkeypox to mpox because the term is misleading.

We may not all need to become experts in tropical and neglected diseases, but I feel we need to collaborate

Science of New Diseases

We need to know what other diseases there are and how they’re mutating and changing. Focusing on the natural world creates the means to keep our ecosystem healthy, including humans. Preparing to cope more effectively for what comes after COVID-19 will keep us from being surprised over and over again.

People will continue traveling for work and pleasure. Cities will continue expanding. The human population will continue growing. The demand for more housing and food and the farms to produce it will continue to transform animal habitats to their detriment and ours. As long as we continue to encroach on animals’ domains, humans will be exposed to more of the diseases they carry.

The convergence of these circumstances and a willingness to respect and explore the animal–human intersection creates an amazing opportunity to expand our knowledge, if we’re willing to shift our perspective to do so.
