At 2:00 p.m. on February 8, 2020, a press conference was held in Shanghai, in which ZHENG Jin, spokesman of Shanghai Health and Health Commission, Zeng Qun, deputy director of Shanghai Civil Affairs Bureau, Zhu Renyi, director of disinfection and infection control department of Shanghai CDC, hang Wenquan, director of Minhang District Health and Health Commission, were invited to introduce the prevention and control of pneumonia caused by new coronavirus in Shanghai.

Some of the recent cases in Shanghai are family clustering cases. At the conference, Zeng Qun stressed that it is very important to further strengthen the prevention and control of the epidemic within the family:

Health and epidemic prevention experts stressed that the main routes of transmission of new coronavirus infection pneumonia that can be determined at present are direct transmission, aerosol transmission and contact transmission.

Direct transmission refers to the infection caused by sneezing, coughing and talking droplets of the patient, and the exhaled gas is inhaled directly in short distance;

Aerosol transmission refers to the mixture of droplets in the air to form aerosols, which lead to infection after inhalation;

Contact transmission refers to the deposition of droplets on the surface of objects, contact with contaminated hands, and then contact with oral cavity, nasal cavity, eyes and other mucous membranes, leading to infection.

In response to these routes of transmission, Zeng Qun called on the community residents to pay attention to the prevention and control of the cluster epidemic, to improve the awareness of family cluster epidemic prevention and control, and to achieve the seven essentials for home-based epidemic prevention:

First, we should cancel all social activities, and dissuade relatives and friends in key epidemic areas from postponing their visit to Shanghai;

Second, we should open windows frequently, ventilate more and keep the indoor air circulating;

Third, do a good job in daily family disinfection: wipe and disinfect key parts such as door handle, table and chair, toilet seat cushion with 75% alcohol or chlorine containing disinfectant;

Fourth, personal hygiene: wash your hands with running water, soap or hand sanitizer before and after meals, and cover your mouth and nose with paper towels or elbows when coughing and sneezing;

Fifth, avoid air and contact transmission: family members should avoid contact with body secretions of suspicious symptoms, and do not share personal necessities; when dining, the public chopsticks should be divided into meals, eat fast, talk less, communicate with each other not close, avoid handshaking and hugging, bow hands and smile and speak etiquette;

Six, strictly do a good job of home isolation: the foreign returnees should cooperate with the relevant investigation, accurately report the facts and actively accept the isolation; those who need home isolation and observation should try to live in separate houses with their families; those with limited conditions should live in separate rooms and separate rooms, and all family members living in the same house should wear masks;

Seventh, pay close attention to the health status of family members, such as fever, cough and other symptoms, should consciously avoid contact with others, wear a good mask and go to the nearest fever clinic as soon as possible, and fully cooperate with the treatment.
