Prevention of parasitic diseases.
Prevention of parasitic infections is simply by placing barriers between the parasites and the potential hosts, which is by avoiding exposure.
Protozoan (amebiasis, flagellates, ciliates, sporozoa, etc.) and helminth (intestinal worms) are most often encountered by fecal-oral routes, contaminated foods, or person-person contact. Prudent adherence to the following will limit exposure and infection:
- Hand-washing, using soap and hot water before and after using the toilet, after changing diapers, and before preparing or eating foods. Be wary of establishments in which you suspect hand-washing for employees is not strictly enforced.
- Avoid frequent hand-shaking.
- Cooking fruits and vegetables with boiled or purified water before eating.
- Wash, peel, or cook all raw fruits and vegetables.
- Thoroughly cook meat.
- Cook at temperatures of at least 145°F (62.8°C) for whole cuts of beef and pork, and 160°F (71°C) for ground meat and poultry.
- Avoid raw fish and meat.
- Avoid soil or water contact which may be contaminated with human or animal feces.
- Avoid walking barefoot, playing in sand-boxes, swimming with open sores or swallowing swimming water in natural settings such as streams, ponds, or small lakes.
