Getting a vaccine is influenza especially important this year because of seasonal flu that spreads throughout the fall and winter may overlap with new coronavirus infections and dual infection with both viruses will greatly increase the need for intervention, he said a Chinese epidemiologist superior.

Zeng Guang, chief epidemiologist at the Center for Disease Control and Prevention, said dual infections have been reported in China and is likely to reach its peak in the autumn and winter.

"There is a high probability that the two respiratory diseases will emerge the same time, then," Zeng said. "Getting a flu vaccine is the most effective way to prevent the spread of flu in the fullest extent."

Zhang Wenhong, director of the department of infectious diseases in Shanghai Huashan Hospital affiliated to Fudan University, Central Television on Sunday that there could be a rebound COVID 19-infections during the fall and told China winter, especially in countries and regions are now seeing increasing cases.

"China, however, has already established a rigorous system of epidemic control and prevention and is fully prepared to contain imported cases," he said. "Getting a flu vaccine will prevent further deterioration of the potential of co-infection."

Sun Tieying, an expert in the airways of Beijing who helped Hubei Province to fight the pandemic in February, agreed, adding that the broader influenza vaccination would also be more easy for doctors to decide whether a patient had influenza or COVID-19.

She said 18 of the 50 COVID-19 patients in serious and critical condition who was treated in Wuhan also had the flu.

A study by the hospital in the town of Wuhan University in February found that laboratory tests of 8,274 close contacts of infected persons on January 20 on February 9 also confirmed that the new coronavirus could accompany other pathogens including influenza H3N2 ay.

"at the beginning, front-line physicians often struggled to distinguish between the new coronavirus and influenza," said Sun.

Zeng said the rate of flu vaccination is low in China and around 2 percent. Vaccine production is also limited, and only about 30 million flu vaccines supplied per year.

It urged government departments to put more effort into the mass production of flu vaccines.

Luqian Yi, deputy director of the Health Commission of Hunan, suggested including flu vaccines as part of the national immunization plan to provide free vaccines for everyone, especially children.

It uses the center of Kaifu district in Changsha, Hunan Province as an example. The district saw a significant drop in flu cases were down approximately 97.3 percent year on year, due to vaccination early to free primary and secondary, as well as the elderly.
