Health experts pin their hopes on long-awaited trials into a new potential vaccine for tuberculosis.
In the few minutes it takes to read this article, some 15 people are likely to have died from humanity’s worst infectious killer disease. Over the course of the day, the toll will be around 3,600.
The victims are likely to have died slowly, spending months or years coughing and wasting away as their lungs were relentlessly weakened.
Those victims are also all likely to have been poor and from the developing world, or middle income countries.
The killer is not an exotic new superbug, or recently-emerged virus, but one of the world’s oldest pandemics, caused by a bacterium which has plagued humanity for an estimated 40 millennia.
Locked in a constant arms race against human immune systems, the bug has in that time evolved into a stubborn, stealthy and difficult-to-stop killer.
Some 10.6m people fell ill with tuberculosis, or TB, in 2022 and 1.5m people died, which is an average of 2.5 deaths per minute.
