Pandemics became the top concern for insurance professionals this year as the Covid-19 crisis roils the industry worldwide. Infectious diseases and pandemics were ranked as the most significant risks to society over the next five to 10 years in a study published Thursday by French insurer Axa SA. That’s a reversal from last year, when climate change was seen as the biggest concern.

Covid-19 is proving to be a major challenge for insurers, especially those that provide cover for canceled events such as sports matches and concerts. Disputes over coverage have led some policyholders to take legal action, with Axa recently losing a lawsuit against five restaurant operators. The insurer said it will appeal the ruling.

The survey of 2,600 insurance professionals in 53 countries, found that 56% of the respondents consider pandemics one of the top five emerging risks, up from 23% in 2019. Climate change is now the second biggest worry overall, but the views vary geographically as it remains the top priority in Europe but falls to third place in the U.S. and Asia.

The reduced emphasis on climate change “is concerning, especially among our American and Asian respondents, as we believe that shorter-term issues around the pandemic should not completely overshadow longer-term threats,” Axa Chief Executive Officer Thomas Buberl said in a statement.
