Abstract
The field of infectious disease is vast, complex and rapidly expanding. New advances in
diagnostic testing, the development of new antimicrobial therapies and even the emergence of novel
infectious diseases require diligent study by medical practitioners to remain current. International
travelling can pose various risks to health, depending on the characteristics of both the traveller and
the travel. Travellers may encounter sudden and significant changes in altitude, humidity, microbes
and temperature, which can result in ill-health. In addition, serious health risks may arise in areas
where accommodation is of poor quality, hygiene and sanitation are inadequate, medical services
are not well developed and clean water is unavailable. The purpose of this paper is to highlight the
details and impact of 4 significant diseases that pose a threat to public health. Specifically issues
are such as the cause, transmission, geographical distribution, nature of disease and precautions of
SARS, influenza, chikungunya and avian flu.
