Many of the Post-70s and post-80s should have eaten a kind of sugar pill. At that time, most people didn't know it was a vaccine, which was used to prevent poliomyelitis, or poliomyelitis. The virus was a major threat to children around the world many years ago, and now the who has declared polio III eradicated.

Polio is a highly contagious disease caused by a virus, according to the WHO. It attacks the nervous system and can cause a total paralysis in hours. The virus is primarily through the faecal pathway, or, in less common cases, through a common approach, such as contaminated water or food, and in the intestinal tract. Initial symptoms included fever, fatigue, headache, vomiting, neck stiffness, and pain in the extremities. There are 1 case of irreversible paralysis (usually the leg) in every 200 cases of infection. In the case of paralysis,5% to 10% of the patients died due to respiratory muscle paralysis.

Polio mainly affects children under the age of five. There is no specific medicine. It is mainly prevented by polio vaccination. Children can get lifelong immunity.

The polio virus is divided into three types: type I, type II and type III, and the three polio viruses are the same in the symptoms caused, and can lead to irreversible paralysis or even death. In the early stages of the illness, other symptoms may include fever, fatigue, and stiffness of the neck and the limbs, although most of the patients (90%) have a very mild and even complete absence of symptoms.

With the active prevention of poliovirus in the world, the number of cases recorded in the world has dropped from 350000 in 1988 to less than 40 today, and the number of affected countries has dropped from 125 to only 2.

Afghanistan and Pakistan are the only two countries that have reported polio cases, while Nigeria, as the third country with polio epidemic, has not experienced cases caused by wild poliovirus type I since July 24, 2014, and is expected to obtain polio free certification in 2020.

The global polio eradication initiative (GPEI), which is composed of the World Health Organization, the United Nations Children's fund and other health partners, has made polio control efforts to save 18 million people from the disease and paralysis.

According to the WHO's latest news, the fatal viral disease of polio has been nearly "completely eliminated" and the number of infected children has fallen by 99 per cent since 1988.

"The news that after smallpox was eliminated, two types of wild poliovirus were eliminated represents a historic achievement for humanity," the who said.

PS: China was called a polio-free country in 2000, and the disease was eventually eliminated in China, thanks also to Mr. Gu Fangzhou, who invented Sugar Pill, who died in January.
