There’s an interesting perspective article published ahead of print in the Emerging Infectious Diseases journal (a Centers for Disease Prevention and Control journal), reviewing border entry screening for infectious diseases in the modern age.

In a previous post, I had mentioned that border entry screening for infectious diseases is not very effective for detecting patients harbouring epidemic/pandemic viruses. Basically, the authors concurred with this view, recommending instead better communications both with local healthcare providers and at the borders for arriving travellers. They had based their conclusions on modelling studies done on the pandemic influenza A(H1N1) virus (in 2009) and the severe acute respiratory syndrome (SARS) coronavirus (in 2003), as well as on published reports of the 2009 influenza pandemic  – including a report from Singapore listing the effectiveness of border screening at Changi airport at 12.9%.
