Lessons for the next pandemic from two years of Covid

The plague declared by the World Health Organization exactly two years ago has not yet ended. Cubid-19 is on the decline in most countries and many are learning to live with it. But after killing 6 million people worldwide, according to official statistics, and more than 18 million, according to New scientific evaluation, Some places are experiencing a resurgence in cases and deaths. Therefore the fight against Sars-Cov-2 virus should remain a top priority for public health as virologists warn against the inevitable emergence sooner or later of new versions that may be more deadly than the dominant omicron today.

The world must also learn from its experience in Cubid to prepare for the next epidemic caused by another pathogen. This is inevitable but even less predictable than the current future. Many scientists think the culprit is most likely a flu or other coronavirus, though there is a scary list of other options, from fan to lassa fever.

There are three related lessons from Covid: reducing the risk of a new pathogen with the potential for an epidemic that appears in the first place; If it does show up, stop spreading around the world; And if it becomes global, develop an effective armamentium of vaccines and treatments as quickly as possible.

Epidemic viruses usually originate in animals. China’s ban on Trade in terrestrial wildlife in food, Shortly after Covid’s appearance, was an important first step and should be enforced. Stronger restrictions on the rampant trade in African bush meat will make a beneficial contribution to both epidemic prevention and nature conservation.

The second stage of epidemic prevention – stopping a dangerous pathogen from spreading far beyond its source – depends on the existence of an excellent global viral surveillance system, followed by an effective isolation policy if an outbreak is detected.

It is debatable whether China could have stopped Cubid originally in 2019. But if the best genomic analysis available today had been applied to samples from the first patients to suffer from the unknown respiratory infection when it began to spread in Wuhan, it would have shown that a new transmissible corona virus was responsible. An immediate closure might simply have saved the world from the plague.

The global ability to read the genetic code of viruses, which has grown greatly over the past two years, must be maintained while Cubid is fading, in order to serve as an early warning system. Expanding the reach of poorer countries will be an important part of any initiative to improve the post-epidemic medical infrastructure in the world.

The third component of the design will ensure that vaccines and drugs develop even faster for the next epidemic than for Cubid. A meeting in London this week was a significant step forward. The Plague Coalition Innovation Coalition (Cepi) has raised $ 1.5 billion in donations for its 100-day mission, which will eventually need $ 3.5 billion.

The goal is to design vaccines and deliver clinical trials, ready for mass vaccination, within 100 days of detecting a new and dangerous virus; By comparison, the brave effort to develop a Covid vaccine lasted 326 days. For the huge research and development program predicted by Cepi will have to supplement even larger sums for pre-purchase commitments, which have been submitted by governments when it may not be clear how big a risk the virus really poses to the world.

But medical science and technology can do so much for readiness. Political cooperation around the world will also be required. If tensions increase following the war in Ukraine, the next epidemic will find a more fertile pillow.
