The World Health Organization has declared an end to COVID-19’s status as a public health emergency of international concern.
After previous public health emergencies likes SARS and H1N1, there was renewed investment in pandemic preparedness, but it was not sustained. We cannot make the same mistake after COVID-19.
This latest outbreak has been deadly for many millions of birds. The risk to humans, however, is very low.

During the 1918 flu pandemic, white people died at similar rates to Black Americans, according to a new study – a very different pattern than what occurred during the COVID-19 pandemic.

Americans with excess weight and obesity have been hit hard by COVID-19. Now there is reason to believe they may not get the same protection from the vaccines.
High-income countries have already bought up stocks of the leading COVID-19 vaccines for the foreseeable future.
Selfishness was also a problem when the world was developing vaccines for swine flu and bird flu.

A team of experts argues that after taking care of essential workers, COVID-19 vaccinations should be given to the greatest transmitters of the virus, who are mostly the young.
A new set of swine flu viruses have been discovered that are highly adapted to infecting humans – and they’re already spreading among farm workers in China.
It’s excellent this virus has been found early, but there is no evidence yet of human-to-human transmission.

Differences in the viruses’ biology and societal contexts mean there’s no guarantee today’s pandemic will mirror the ‘waves’ of infection a century ago.
The pangolin, one of the most poached animals in the world, could have served as an intermediate host in the transmission of SARS-CoV-2 to humans.
Covid-19, like other major epidemics, is not unrelated to the biodiversity and climate crisis we are experiencing.
