Why Does Polio Still Exist in Some Countries Today?
Published
Polio has been almost eliminated from most countries of the world, but Pakistan and Afghanistan are among the few countries where the disease is still found. The question is why the same disease remains in some countries while it does not in others.
Polio is caused by a virus that mostly affects children under the age of five. The virus spreads through contaminated water and unsanitary conditions. In areas where the sanitation system is weak, the risk of this virus spreading is higher. According to experts, the most important step in eliminating this disease is to ensure that as many children as possible are given vaccine drops on time.
In countries where vaccination coverage is complete, the disease has been brought under control. However, in some areas, many children are unable to be included in the campaign due to parental hesitancy, misinformation, security problems, and population displacement. When some children are not protected, the virus continues to circulate among them.
In Pakistan, the government and health workers run anti-polio campaigns and try to give drops to children by going door to door. Experts say that completely eliminating this disease requires sustained effort, parents' trust, and an improved sanitation system.
