The COVID-19 pandemic was unprecedented in terms of the scale, duration, impact on medical systems and subsequent closure of borders and cessation of travel. It is important to note that several other endemic or epidemic outbreaks of disease, including other coronavirus (SARS, MERS) have occurred in the previous two-decades without as virulent a spread or significant public health response.
The next outbreak of endemic or epidemic disease does not immediately indicate that all travelers will need to return home, or that all programs will be cancelled. However COVID-19 has demonstrated that the worst case scenario – what if all global travel immediately ceases – can occur and should be planned for. Temple has taken these into account when setting forth it's standards for international group travel.
