The Problem of Pandemics

 Each year on average more than 3 million people die from zoonotic diseases, those that spill over from wildlife into humans. The analysis assesses every zoonotic virus over the last century known to have killed more than 10 people, including the Spanish flu, repeated bird flu outbreaks, Marburg virus, Lassa fever, Ebola, HIV, Nipah, West Nile, Sars, Chikungunya, Zika and Covid-19.

Wildlife is known to harbour vast numbers of viruses, and outbreaks are increasing in frequency and severity. Since the start of the Covid-19 pandemic, experts have repeatedly warned that the root causes must be tackledInaction has left the world playing an “ill-fated game of Russian roulette with pathogens”, they have said, and protecting nature is vital to escape an “era of pandemics”.

  Scientists heavily criticise approaches by global bodies and governments that focus only on preventing the spread of new viruses once they have infected humans, rather than tackling the root causes as well. “That premise is one of the greatest pieces of folly of modern times,” said Prof Aaron Bernstein, of the Center for Climate, Health and the Global Environment at Harvard University. 

“Our salvation comes cheap because prevention is much cheaper than cures,” Bernstein said. “If Covid-19 taught us anything, it is that we absolutely cannot rely on post-spillover strategies alone to protect us. Spending only five cents on the dollar can help prevent the next tsunami of lives lost to pandemics by stopping the wave from ever emerging, instead of paying trillions to pick up the pieces.”

Bernstein said action to stop pandemics at source had been ignored because “ this primary prevention does not result in profits for corporations,” he said.
