7 deadly diseases the world has (almost) eradicated

It’s easy to feel pessimistic about the health of the world’s population. Growing antibiotic resistance, the dramatic rise in obesity related diseases and problems associated with an ageing population are all cause for concern.

But how about the diseases that mankind is winning the fight against? The truth is, we are on the brink of eradicating a string of deadly diseases that were, until recently, affecting millions of people.

It has been 35 years since the World Health Organization declared that smallpox had been eradicated. Now there are hopes that similar declarations will be made about a number of other killer diseases in the coming years.

Guinea worm
Caused by a parasite caused dracunculiasis which means “affliction with little dragons” in Latin, Guinea worm is exceedingly painful and can be permanently debilitating, especially in children.

The worm, which spreads via dirty drinking water, can destroy the muscles and tissue surrounding a knee or inside a foot leaving young children unable to walk for the rest of their lives.

In 1986 there were 3.5 million cases of Guinea worm reported globally. By 2015, that was down to 22 cases and so far in 2017, there have been only 3 individual cases reported.

According to the The Carter Center, Guinea worm “is set to become the second human disease in history, after smallpox, to be eradicated.”

Measles
Like smallpox, measles is highly contagious. Its most serious complications include blindness, severe diarrhea, serious respiratory infections and encephalitis, an infection that causes brain swelling.

Measles can also have a crippling long-term effect on children's immune systems, leaving them susceptible to other infectious diseases. This makes the measles vaccine even more important.

Aside from localized outbreaks associated with parents refusing vaccinations for their children, measles has been largely eliminated in most affluent countries, and deaths from measles across the globe have dropped by 75% since 2000.

While the virus is still common in many developing countries, particularly in parts of Africa and Asia, the WHO hopes to eliminate the disease globally by 2020.

Mumps
Mumps is a contagious disease that typically causes the salivary glands in the cheeks and jaw to swell. While most cases do not cause lasting damage, it can result in severe complications that include encephalitis or meningitis, swelling of the ovaries or breasts and deafness.

Before children in the US started getting routinely vaccinated against mumps (the “MMR vaccine” is typically given in two doses and is 97% effective against mumps, measles, and rubella), it was a common illness in children and young adults. In 1964, there were roughly 212,000 cases in the US.

Today, mumps outbreaks are rare, although they do happen occasionally, such as the 2009 outbreak that involved about 3,500 cases, primarily in New York.

Rubella
Rubella is a highly contagious disease which in young people and adults usually only causes a rash and cold-like symptoms. But it is highly dangerous for unborn babies in their first trimester and can cause deafness, blindness and brain damage.

Rubella has been officially declared eliminated from the Americas but with around 120,000 children a year born around the world with severe rubella-related birth defects, there's still a lot of work to do.

Polio
Polio is a crippling and sometimes deadly infectious disease for which there is no cure.

While most people who catch the disease recover fully, in about 1% of cases polio can leave its sufferers with permanent physical disabilities. The virus spreads along the nerve fibers in the spinal cord and eats away at the nerves inside the parts of the body that allow us to move.

Among people with polio who become paralyzed, about 5% to 10% die when the muscles that control their breathing are rendered immobile by the virus.
