The World Health Organization collates a vast amount of data on the prevalence of all infectious diseases, and has recently updated its top 5 list:
- Hepatitis B
- Malaria
- Hepatitis C
- Dengue
- Tuberculosis
With both Hepatitis B and Hepatitis C particularly prominent in their position on this list it is worthy of repeating, that great care must be taken with needles, with other sharps and with any other bloodstained wastes.
