Malaria has called more people that wars through out human history combined
Malaria has called more people that all wars through out human history combined.
Thanks to eradication efforts.
It is fall less common that it once was.
But every year, malaria still kills a quarter of million children.
The most vulnerable group.
In Africa alone.
But again and again,
the diseases become the resistant the treatment use to defeated.
Malaria cases starting humans
with a bite from certain kinds of an awful ease Gambian mosquito.
During the bite,
malaria parasites injectd into bloodstream and travel to the liver.
In this next stage,they muitiply and rapture liver cells,
then they infect red blood cells destroyed them.
Anti-malaria drugs work by attacking the malaria parasite in the blood cells.
But the malaria parasite has adapted time and again.
lt has form to resistance to some of most powerful anti-malaria drugs
from chloroquine to mefloquine.
Malaria has ability to resist drugs.
lt’s one of the reasons success in eradicating it has levaled off.
New ways to tackle malaria are being developed.
seeking to wipe out the mosquitoes the carry the disease.
A gene editing technology called CRISPR is being use to engineer a gene drive.
This create selfish genes that always passed on to offspring.
The aim is to interfere the fertility
by driving a gene for sterility through entire population.
As it is pass from generation to generation,
the population would be swamped with insects
that are unable to reproduce.
In theroy, they could be driven to extinction.
Last year, a team at Imperial College London
successfully created the gene drive
that wiped out enclose cohorts of one species of malaria carrying mosquito.
but there is no garenteen
that gene drives could work many of environments
where malarias found in the world.
Specially in Africa,
humanity had shown that it can control malaria.
It has been eradicated in around 35 countries
calling the best hope lies the combination of macips.
But in the future,
A gene drive maybe the most effective solution.
Coming up next , should we screen for lung cancer.
