Objective: To improve clinician’s understanding of dengue fever. Methods: The clinical data of 201 dengue fever patients admitted to the First People’s Hospital of Liangjiang New Area from August to October

2019 were retrospectively analyzed. Chi-square was used for discontinuous variables

and t test was used for continuous variables. Results: Among 201 dengue fever patients

97 (48.26%) were male

and 104 (51.74%) were female. The number of them over 60 years old was 40 (19.90%). The common manifestations included fever (99.00%)

feeble (85.07%)

and myalgia soreness (85.57%). Laboratory examination showed that most patients had neutropenia (90.53%)

thrombocytopenia (70.00%)

and liver function damage (30.00%). The incidence of thrombocytopenia was higher in elderly patients than that in young and middle-aged patients (66.67% vs. 85.25%

P=0.04). In addition

the incidence of liver damage in the elderly patients was higher (50.00% vs. 25.64%

P=0.01)

with more serious damage. Etiological examination showed that all patients’ dengue virus RNA (DENA-RNA) were positive

the locally infected patients were genotype 1

and two imported patients were genotype 2 and genotype 3. All patients were treated by symptomatic support to prevent complications

most patients with mild symptoms and with good prognosis. Conclusion: In 2019

the epidemic of dengue fever in our district is mainly genotype 1

with fever

fatigue

myalgia soreness as typical clinical features

accompanied by neutropenia

thrombocytopenia and liver function damage

especially in elderly patients

which should be paid great attention to.
