The COVID-19 pandemic continues to present enormous challenges for colleges and universities and strategies for save reopening remain a topic of ongoing debate. Many institutions that reopened cautiously in the fall experienced a massive wave of infections and colleges were soon declared as the new hotspots of the pandemic. However, the precise effects of college outbreaks on their immediate neighborhood remain largely unknown. Here we show that the first two weeks of instruction present a high-risk period for campus outbreaks and that these outbreaks tend to spread into the neighboring communities. By integrating a classical mathematical epidemiology model and Bayesian learning, we learned the dynamic reproduction number for 30 colleges from their daily case reports. Of these 30 institutions, 14 displayed a spike of infections within the first two weeks of class, with peak seven-day incidences well above 1,000 per 100,000, an order of magnitude larger than the nationwide peaks of 70 and 150 during the first and second waves of the pandemic. While most colleges were able to rapidly reduce the number of new infections, many failed to control the spread of the virus beyond their own campus: Within only two weeks, 17 campus outbreaks translated directly into peaks of infection within their home counties. These findings suggests that college campuses are at risk to develop an extreme incidence of COVID-19 and become superspreaders for neighboring communities. We anticipate that tight test-trace-quarantine strategies, flexible transition to online instruction, and-most importantly-compliance with local regulations will be critical to ensure a safe campus reopening after the winter break.

OSD definitions vary between European countries and are not directly comparable, which hampers comparisons between statistics collected in different countries. Awareness of this fact and further efforts for standardization are necessary.

In this study, superficial fungal infections were reported more commonly in female (n = 207) than in male (n = 182) patients. M. canis was the chief agent of tinea capitis and tinea corporis, whilst T. rubrum was the main causative agent of tinea pedis, tinea manuum, and tinea unguium. Onychomycosis due to Candida species was more common in female than in male patients.

Ninety-five randomly selected human immunodeficiency virus (HIV)-seropositive Air Force personnel were psychiatrically examined during a routine medical evaluation. Of the 95, 95% did not have acquired immunodeficiency syndrome and were largely asymptomatic; 61.1% had clinical axis I diagnoses, which included simple phobia, adjustment disorders, hypoactive sexual desire disorder, alcohol use disorder, major depression, and organic mental disorders; 30.5% had personality disorders. Significantly higher frequencies (p less than 0.05) of simple phobia and hypoactive sexual desire disorder were noted with knowledge of HIV seropositivity. Disorders that occurred more commonly than in age-matched Epidemiologic Catchment Area (ECA) participants included: simple phobia, antisocial personality disorder, alcohol abuse, and organic mental disorders. The high prevalence of major psychiatric illness in this sample supports the notion that screening for psychiatric illness, and counseling where indicated, should be integral to HIV screening programs.
