Chinese authorities are saying they have eradicated smallpox and Mac viruses, in a step toward eradication.
The Global Polio Eradication Initiative said in a statement Thursday that the two new strains were the first since the eradication campaign started in 2015, when China was the only country in the world that reported the virus.
“China has successfully eradicated the second strain, and the virus is not spreading,” the statement said.
“It has become a rare and treatable virus, and has been eradicated in the country.
It is important to note that these two strains are different, with different characteristics and with a different sequence of genes.”
The first Chinese strain was discovered in 2014 in northern Hunan province.
That strain was then used to wipe out the country’s entire virus herd and halt a pandemic that had killed about a quarter of a million people.
