he first stage
During the early stage of the outbreak, the main strategy focused on preventing the  
exportation of cases from Wuhan and other priority areas of Hubei Province, and preventing  
the importation of cases by other provinces; the overall aim was to control the source of  
infection, block transmission and prevent further spread. The response mechanism was  
initiated with multi-sectoral involvement in joint prevention and control measures. Wet  
markets were closed, and efforts were made to identify the zoonotic source. Information  
on the epidemic was notified to WHO on 3 January, and whole genome sequences of the  
COVID-19 virus were shared with WHO on 10 January. Protocols for COVID-19 diagnosis and

treatment, surveillance, epidemiological investigation, management of close contacts, and  
laboratory testing were formulated, and relevant surveillance activities and epidemiological  
investigations conducted. Diagnostic testing kits were developed, and wildlife and live  
poultry markets were placed under strict supervision and control measures.
The second stage
During the second stage of the outbreak, the main strategy was to reduce the intensity of  
the epidemic and to slow down the increase in cases. In Wuhan and other priority areas of  
Hubei Province, the focus was on actively treating patients, reducing deaths, and preventing
exportations. In other provinces, the focus was on preventing importations, curbing the  
spread of the disease and implementing joint prevention and control measures. Nationally,
wildlife markets were closed and wildlife captive-breeding facilities were cordoned off. On
20 January, COVID-19 was included in the notifiable report of Class B infectious diseases and  
border health quarantine infectious diseases, with temperature checks, health care  
declarations, and quarantine against COVID-19 instituted at transportation depots in  
accordance with the law. On 23 January, Wuhan implemented strict traffic restrictions. The  
protocols for diagnosis, treatment and epidemic prevention and control were improved;
case isolation and treatment were strengthened.  
Measures were taken to ensure that all cases were treated, and close contacts were isolated  
and put under medical observation. Other measures implemented included the extension  
of the Spring Festival holiday, traffic controls, and the control of transportation capacity to  
reduce the movement of people; mass gathering activities were also cancelled. Information  
about the epidemic and prevention and control measures was regularly released. Public risk  
communications and health education were strengthened; allocation of medical supplies  
was coordinated, new hospitals were built, reserve beds were used and relevant premises  
were repurposed to ensure that all cases could be treated; efforts were made to maintain a  
stable supply of commodities and their prices to ensure the smooth operation of society.
The third stage
The third stage of the outbreak focused on reducing clusters of cases, thoroughly controlling  
the epidemic, and striking a balance between epidemic prevention and control, sustainable  
economic and social development, the unified command, standardized guidance, and  
scientific evidence-based policy implementation. For Wuhan and other priority areas of  
Hubei Province, the focus was on patient treatment and the interruption of transmission,  
with an emphasis on concrete steps to fully implement relevant measures for the testing,  
admitting and treating of all patients. A risk-based prevention and control approach was  
adopted with differentiated prevention and control measures for different regions of the  
country and provinces. Relevant measures were strengthened in the areas of  
epidemiological investigation, case management and epidemic prevention in high-risk public  
places.  
New technologies were applied such as the use of big data and artificial intelligence (AI) to  
strengthen contact tracing and the management of priority populations. Relevant health  
insurance policies were promulgated on "health insurance payment, off-site settlement, and  
financial compensation". All provinces provided support to Wuhan and priority areas in  
Hubei Province in an effort to quickly curb the spread of the disease and provide timely  
clinical treatment. Pre-school preparation was improved, and work resumed in phases and
batches. Health and welfare services were provided to returning workers in a targeted and  
‘one-stop’ manner. Normal social operations are being restored in a stepwise fashion;  
knowledge about disease prevention is being popularized to improve public health literacy  
and skills; and a comprehensive program of emergency scientific research is being carried  
out to develop diagnostics, therapeutics and vaccines, delineate the spectrum of the  
disease, and identify the source of the virus.

« Des tests innovants et trop chers »
Si les laboratoires n'ont pas encore la possibilité de faire passer les tests « c'est parce qu'ils sont innovants et qu'ils coûtent trop cher », croit savoir le docteur Ramo, directeur d'un laboratoire d'analyse dans la ville voisine de Chelles (Seine-et-Marne).
 
« Lors de l'épisode de propagation du virus H1N1, il s'était passé la même chose, se souvient le praticien. On a reçu les tests en laboratoire un an après le pic du virus, quand plus personne n'était menacé. »
