Abstract

This review highlights the impact of emerging diseases; emerging diseases and pathogen dispersion; disease spread; and possible causes contributing to the emergence of pathogens. Some diseases are caused by potentially dangerous pathogens that have led changes in humanity. Despite our efforts in the fight against these dangerous pathogens; the influences of natural phenomena such as hurricanes or strong winds that disperse pathogens remain. However, some actions such as investment in research priorities that are focused on quarantined pathogens and official regulations can help in disease prevention. We discuss emerging diseases as a threat to crops, identify future research areas, and encourage the establishment of research networks focused on quarantine pathogens to address the problem and minimize risks.
