China is facing the serious situation of 2019-novel coronavirus (2019-nCoV) infection. The health care institutions have actively participated in the prevention, diagnosis, and treatment of the disease. Proper regulation of in-hospital policy may help control virus spreading. We developed seven key clinical questions about the prevention and control of 2019-novel coronavirus infection in hospital, and provided recommendations based on the best available evidence and expert experience. We interpreted the recommendations for better feasibility in Chinese hospital. The current recommendations provide evidence and reference for the domestic medical institutions to reasonably adjust the hospital workflow during 2019-nCoV infection period..
To reduce the infection risk of 2019-novel coronavirus and to protect medical staffs, “Graded personal protection scheme for preventing medical staffs from 2019-novel coronavirus infection in West China hospital” was formulated according to the guidance and notice issued by the National Health Commission combined with the actual situation of West China Hospital. This scheme could provide reference for preventing such disease for medical staffs.
Objective To discuss the epidemiological characteristics of young and middle-aged people infected with COVID-19 in Gansu province under the new epidemic policy. Methods A total of 1800 people were collected from two tertiary hospitals in Gansu province from November 8, 2022 to January 28, 2023. The vaccination status, nucleic acid antigen detection, the specific time of infection, main symptoms and severity of the disease were investigated. Results Among 1800 participants, 1685 (93.6%) were vaccinated and 1565 (86.9%) were infected with COVID-19. Among the 1565 infected persons, 523 (33.4%) completed both nucleic acid and antigen testing, 382 (24.4%) completed nucleic acid testing, 490 (31.3%) completed antigen testing, 170 (10.9%) received IgG testing. 1490 (95.2%) were slight ill, 75 (4.8%) were critical ill, and 96 (6.1%) were hospitalized, and no one died. In 2022, 92 cases (5.9%) were infected in the first half of November, 141 cases (9.1%) in the second half of November, 630 cases (40.3%) in the first half of December, and 553 cases (35.4%) in the second half of December. 109 cases (7.0%) were infected in the first half of January, 38 cases (2.2%) in the second half of January, and 2 cases (0.1%) in the first half of February of 2023. and no cases in the second half of February. Among the 1565 infected persons, 825 (52.7%) had respiratory symptoms, 293 (18.7%) had gastrointestinal symptoms, 257 (16.4%) had autonomic disorders, 140 (8.9%) had other symptoms such as decreased smell and taste, and 48 (3.3%) had no symptoms after infection. Conclusions The vaccination rate of young and middle-aged people in Lanzhou city of Gansu Province is high. Since the new policy, the infection rate of the novel coronavirus among young and middle-aged people is high, the number of antigen tests is more than nucleic acid tests, most of the infected patients are slight, with fewer critical patients, and the hospitalization rate is low. The peak of infection occurred in early December 2022, and the infection rate was basically zero by February 2023. The main symptoms of COVID-19 infection are mainly respiratory tract, followed by digestive tract and autonomic nervous system disorders, and few patients are completely asymptomatic.
From December 2022 to January 2023, 4 lung transplant recipients were hospitalized in the Department of Thoracic Surgery of the First Affiliated Hospital of Xi'an Jiaotong University due to COVID-19 infection after surgery, of whom 3 were cured and 1 died. The clinical manifestations were mostly characterized by elevated body temperature accompanied by shortness of breath, and indicators such as heart rate, oxygen saturation, and oxygenation index can reflect the severity of the condition. Antiviral therapy requires timely adjustments to immunosuppressive drugs, upgraded oxygen therapy, anti-bacterial and anti-fungal therapy, prone ventilation, general treatment, and anticoagulant therapy, depending on the situation. We should pay attention to monitoring during the course of the disease, and follow up closely after discharge.
