Explanation:

Giardiasis is an infection in the small intestine caused by the protozoan Giardia. Infection occurs primarily when a person eats protozoan cysts (the way the parasite acquires to withstand unfavorable environmental conditions until it reaches a host) present in faeces-contaminated food and untreated water. Because of this form of transmission, it is very important to have clean food ingested by the community and proper water treatment, so Tia can help prevent her community from preventing the spread of the disease by taking measures to test urban settings with more often.

1. cold turkey (no outside ). about 90% of people who try to quit smoking do it without outside support -- no aids, therapy, or medicine. although most people try to quit this way, it's not the most successful method. only about 5% to 7% are able to quit on their own.

2. behavioral therapy. this involves working with a counselor to find ways not to smoke. together, you'll find your triggers (such as emotions or situations that make you want to smoke) and make a plan to get through the cravings.

3. nicotine replacement therapy. there are several types, including nicotine gum, patches, inhalers, sprays, and lozenges. they work by giving you nicotine without the use of tobacco. you may be more likely to quit with nicotine replacement therapy, but it works best when you use it with behavioral therapy and lots of support from friends and family. and remember that the goal is to end your addiction to nicotine, not simply to quit using tobacco.
