Background:

Since December 2019,when coronavirus disease 2019 (Covid-19) emerged in Wuhan city and rapidly spread throughout China, data have been needed on the clinical characteristics of the affected patients.

Methods:

We extracted data regarding 1099 patients with laboratory-confirmed Covid-19 from 552 hospitals in 30 provinces, autonomous regions and municipalities in mainland China through January 29,2020. The primary composite end point was admission to an ICU, the use of mechanical ventilation, or death.

Results:

The median age of the patients was 47 years; 41.9% of the patients were female. The primary composite end point occurred in 67 patients (6.1%), including 5 % who were admitted to the ICU, 2.3% who underwent invasive mechanical ventilation and 1.4% who died. Only 1.9% of the patients had a history of direct contact with wildlife. Among nonresidents of Wuhan, 72.3% had contact with residents of Wuhan, including 31.3% who had visited the city.

Symptoms:

The most common symptoms were fever ( 43.8%), and Cough (67.8%). Diarrhea was uncommon (3.8%).

Incubation Period:

The median incubation period was 4 days. On admission, ground-glass opacity was the most common radiological findings on chest computed tomography (CT) (56.4%).

Conclusions:

During the first 2 months of the current outbreak, Covid-19 spread rapidly throughout China and caused varying degree of illness. Patients often presented without fever and many did not have abnormal radiological findings. But China control this pendamic disease very smartly and shows the world that living nations can control every type of calamity and disaster with the help of their people.
