ABSTRACT
Objective:To analyze the clinical characteristics of monkeypox patients.Methods:The clinical data and laboratory findings of 4 patients with monkeypox patients diagnosed at Yiwu Central Hospital in July 2023 were analyzed. Herpes fluid and skin tissue samples were collected, the viruses were isolation and cultured in African green monkey kidney cells (Vero) and identified with whole gene sequencing.Results:All four patients were male, aged 24-35 years. All patients had male-to-male behavior within 21 days before onset of the disease. Among them, one patient has AIDS and one patient has syphilis. Four patients presented with perineal skin lesions with itching, and 3 patients were found to have enlarged lymph nodes upon admission. Laboratory testing: lymphocyte abnormality (4.57×10 9/L) in 1 case; increased procalcitonin (0.25 ng/mL) in 1 case; elevated IL-10 levels ( 7.11 ng/L and 9.42 ng/L) in 2 cases; increased IL-6 (66 ng/L) and IL-4 (3.24 ng/L) in 1 case, respectively. One case had abnormal myocardial zymogram with a elevated lactate dehydrogenase level of 313 U/L. The monkeypox virus was isolated from lesion tissue and herpes fluid, and the whole gene sequencing identified it as the B. 1.3 subtype of the IIb evolutionary branch, exhibiting typical pathological effects on Vero cells. Conclusion:The clinical manifestations of the 4 monkeypox patients confirmed in Zhejiang province are mild, patients had a definitive history of male-to-male sexual behavior and the virus strains belong to the B. 1.3 lineage of the IIb evolutionary branch.
ABSTRACT
Objective To evaluate the performance of Zika virus (ZIKV) disease prevention and control.Methods Descriptive epidemiological analysis was conducted on the clinical manifestations,laboratory detection results and disease progression of the third imported ZIKV disease case in the mainland of China.Results On 19 February 2016,a ZIKV disease case was confirmed in Yiwu,Zhejiang province,which was the third imported case of ZIKV disease confirmed by China CDC laboratory and expert consulting.The patient just had a travel to Fiji and Samoa and had mosquito bite history in Samoa.The patient was hospitalized on 16 February after the onset on 14 February and the eruption on 15 February.The body temperature of the patient became normal on 17 February,the rash disappeared on 19 February and the conjunctivitis resolved on 20 February.The positive detection of the viral nucleic acid in blood was only for 3 consecutive days,and the viral nucleic acid could be detected in urine even after negative detection in blood for 4 days.Conclusion The symptoms of the patient were typical.ZIKV can be detected by using blood sample in early phase,but after body temperature become normal,the virus can be detected in urine.
