The health authorities in China have detected a new wave of the Coronavirus (known also as COVID-19).
These authorities warn that the new strain is the worst after that strain was detected in Wuhan in December 2019.
The Chinese officials announced the spread of a new wave of COVID-19, starting from Nanjing Airport, the capital of Jiangsu Province in eastern China.
The new wave of infections has extended to Beijing, the capital city of China, and 5 other provinces.
They considered that strain the most serious prevalent after Wuhan's virus.
However, the local media indicated that since the discovery of the first confirmed case of the latest wave on July 20 at Nanjing Lukou International Airport, nearly 200 infections have been reported as of Thursday morning.
Local sources continued to say that compared to the previous waves of local virus resurgence that were usually limited to one or a few nearby cities, t but the Nanjing epidemic occurred in a crowded international airport, and passengers across the territory traveling long distances quickly carried the virus across the country to places including Sichuan in the southwest of the country, and Liaoning in the northeast of China.
"The highly contagious "Delta" strain has led to the rapid spread of the virus nationwide," said a respiratory expert at Peking University First Hospital, Wang Guangfa.
He added, "It is time for us to discover potential gaps in our epidemic prevention and control efforts."
He noted that even cities that have not found infections associated with the new wave should remain on alert
On the other hand, on July 2, China's Foreign Minister Wang Yi urged the international community to build the " great wall" of immunity against the Coronavirus (known also as COVID-1).
Wang Yi addressed the ninth edition of the International Forum of Peace held at Tsinghua University in Beijing, China.
He said that the nations of the world must face the imminent challenges resulted from COVID-19 together.
He added that the most persistent priority is how to build the great wall of immunity to deter the deadly virus, transcend political discrimination and implement international cooperation to combat the epidemic.
China detected the Coronavirus for the first time lately in 2019 but it donated more than 480 million doses of the anti-corona vaccine to other countries across the planet.
The Chinese minister assured that his country will continue working to improve methods of getting the vaccines and affordability in developing countries.
