Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Leptospirosis cases were reported in 11 cities, mainly concentrated in the southern cities of Wenzhou City, Lishui City and Taizhou City(a total of 68 cases), accounting for 81.93% of the total number of cases. August to October were high incidence months for leptospirosis (a total of 70 cases), accounting for 84.34% of the total number cases. The male to female ratio of patients was 4.53 ∶ 1.00, and all were adults ≥20 years old, the middle and old people aged 45 - 79 years were the high-risk population (a total of 77 cases), accounting for 92.77% of the total number of cases. The patient's occupation was mainly farmers, with a total of 54 cases, accounting for 65.06% of the total number cases. The shortest time from onset to initial diagnosis for patients with leptospirosis was 0 day, and the longest was 13 days. The shortest time from initial diagnosis to confirmed diagnosis was 0 day, and the longest was 16 days. The 72.29% of the leptospirosis cases (60 cases) had a history of field labor or suspected contact with contaminated water within one month before the onset of the disease, and 18.07% of the leptospirosis cases (15 cases) had a history of contact with animals such as mice, frogs, pigs, cows, dogs, fish or ducks, or their excreta within one month before the onset of the disease. The average nucleic acid positive rate of host animals with leptospirosis was 5.92% (31/524) in mouse kidney, 6.74% (36/534) in frog kidney, and 0.66% (1/151) in pig kidney. The isolation and culture of leptospirosis from duck kidney, nucleic acid detection, and antibody detection in duck blood were all negative. The leptospirosis bacteria detected in human population were serogroup Icterohaemorrhagiae (3 samples) and Hebdomadis (4 samples), and the bacteria group detected in host animals was serogroup Icterohaemorrhagiae (3 samples). Conclusions:The outbreak of leptospirosis in Zhejiang Province mainly occurs in the summer and autumn, with the affected areas mainly concentrated in the southern region of Zhejiang Province. The affected population is mainly middle-aged and elderly males, and the population carrying Leptospira is still mainly composed of the serogroup Icterohaemorrhagiae and the Hebdomadis, with the host animal being the serogroup Icterohaemorrhagiae.
