The Invisible Siege: The Rise of Coronaviruses and the Search for a Cure by Dan Werb
Coronaviruses have been around for a long time. However, they have only been extensively studied in the past few decades. Previously they were most commonly seen as just causing a common code and only studied by an odd dedicated researcher. This all changed with SARS. It appeared in Asia in the early 2000s. It was deadly and started to attract a great deal of interest. There was work to sequence as well as to identify the source. Work was also started on vaccines. However, after it was contained, the enthusiasm died off.
A decade later, Mers appeared. This was also extremely deadly. Interest in Coronaviruses popped up again. It also lead to tracing the source - and identifying camels instead of bats as an animal vector. This one was also contained, and interest again died off.
In 2020, Covid-19 started to spread. The people had been doing work on coronaviruses and vaccines were ready to jump into action. Covid-19 ended up causing a widespread worldwide pandemic. People could carry and spread the virus without showing symptoms. It could be deadly for some people, but for others they suffered minimal (or no symptoms.) This allowed it to spread much more than the previous viruses. Luckily, the past research enabled vaccines and treatments to be quickly put into place. (Though in the field of medical research, a year is seen as amazingly fast.)
This book covers the history of coronavirus research. It does a great job of putting Covid-19 in context of the previous viruses. There are a number of factors involved. Politics and relationships can be as important as science. Countries and rulers are reluctant to admit they have a problem. This can make it difficult for scientists and public health official to identify and combat the virus. One scientist that had success built up relationships by way of non-judgemental science. Science also had internal conflicts, with those advocating open science versus those concerned about patents and financial return. Money is needed to bring drugs to market, but if vaccines are too expensive, the poorer parts will not receive it, limiting world immunity.
