It is unclear whether this emerging zoonotic infection poses a threat to humans. A previous study in 2012 showed surprisingly high rates of seropositivity and positive viral detection by RT-PCR in duck farm workers in China. To understand the nature of the threat of this emerging virus, we studied the neutralizing antibody response to a local isolate of DTMUV in an at-risk population, who were workers in duck farms and residents around farming areas in Central Thailand where DTMUV had been previously detected, and in a not-at-risk population, who were people living in the same or neighbouring province, but at a distance from the farms and who had no contact with ducks. The sera from the at-risk population showed higher anti-DTMUV neutralizing antibody titres as compared with those of the not-at-risk population. However, within the at-risk population, workers with direct contact with ducks did not show higher neutralizing titres than those without direct contact. Interestingly, some people in the not-at-risk group also displayed high neutralizing antibody titres to DTMUV. These sera were tested against other endemic Flaviviruses and showed no or low cross-reactivity suggesting the specificity of the neutralizing activity against DTMUV. These data raise a possibility of DTMUV as a potential zoonotic pathogen but the mode of transmission of the virus from ducks or other possible hosts to humans should be explored further.Methotrexate, a folic acid analog, is the conventional systemic anti-psoriatic agent most commonly chosen for combination with biologics in the treatment of psoriasis. Real-world long-term safety data of this combination versus biologic treatment alone in dermatological practice are sparse. Here, we present results of a comparative retrospective study of laboratory dynamics and adverse events in psoriatic patien
