摘　　要：To the Editor:Human pathogens have evolved over a long time to become mesophiles to adapt to the typical 37°C temperature of the human body.Yeast and yeast-like fungi also grow very well at this temperature,while the optimal temperature for the growth of filamentous fungi is 25 to 28℃.Hainan Island in China has a tropical oceanic monsoon climate with indistinct seasons.The mean temperature at this place for many years has been 24.4℃,and the annual temperature variation is small;the precipitation is approximately 1718.6 mm,and the relative humidity is 82%.These unique weather characteristics provide a favorable growth environment for pathogens.Patients with hematologic malignancies have poor immunity and are susceptible to pathogens.This results in high nosocomial infection rates in patients with hematologic malignancies and frequent antibiotic use.Epidemiological surveys of different regions and hospitals can provide more guidance for clinical drug administration by hematologists in treating infections in patients with hematologic malignancies.
