A Review on Public Health Concern Caused by Escherichia coli O157:H7

Abstract

The public health issues related to Escherichia coli safety remains a major issue in the 21st century which affects both the advanced and third-world countries. Hemorrhagic fever caused by E. coli O157:H7 has become a global public health dilemma. Worldwide incidences cause by E.coli particularly O157:H7 make it an important pathogen that occurred in all countries. Infection cause by O157:H7 range from asymptomatic which may become severe in some cases. Escherichia coli O157:H7 can cause infections at a very low dose in humans which is a much lower dose than for most other pathogens of the intestines. Its preference to thrive within the warmer-temperature seasons compared to periods with low temperatures make it a novel pathogen in the tropical regions. It can cause infections at a very low dose in humans which is a much lower dose than for most other pathogens of the intestines: Despite the vital community and clinical health hazards pose by E. coli O157:H7 worldwide, a very few studies were conducted in developing countries. Continues surveillance to determine the prevalence of the pathogen as well as accurate diagnostic procedures may immensely help in tackling the pathogen.
