Giardia is a parasite that causes the diarrheal disease Gardiasis. It is frequently found on surfaces, in soil, food or water that had been contaminated by fecal material. The structure of Giardia allows it to live for long periods outside of a host. The most common mode of transmission is through drinking contaminated water.
Giardiasis is the most frequently diagnosed intestinal disease. Symptoms can last from 1 to 2 weeks or sometimes longer; frequent symptoms include, diarrhea, gas, greasy stool, stomach and abdominal cramps, upset stomach and nausea, as well as dehydration. Less common symptoms may include itch skin or hives, and swelling of the eyes and joints. Diagnosis is usually done through the collection of stool samples. Treatment is provided by several drugs, these include metronidazole, tinidazole, and nitazoxanide. Prevention is easy and simple. Good hygiene practices are important for the prevention of Giardiasis. The most common prevention technique is washing hands before preparing food, after using the bathroom, after touching and animal, and before and after treating a cut or wound.
Overall, much like other diseases prevention is the easiest way to protect from the contraction of Gidariasis. Common good hygiene rules are the best way to protect your self from contracting Giardiasis.
A Recreational Water Illness

As the hot beaming sun and
humidity strive among us during the summer months, many people would go to
beaches to cool down, however those to choose to remain close to home, opt for
public pools. Though attending public pools has certain requirements, such as
showering after using the restroom and practice proper hygienic. However a study
shows that 1 in 5 Americans use pools as a restroom, while 7 in 10 do not shower
before or after being in a pool. These poor practices can
contribute to gastroenteritis outbreaks. One of the many disease, giardia
or giardiasis is a germ can live up to 45
minutes in contaminated water because of its tough outer shell, even if the
water is properly chlorinated. In 2013, 23 cases of giardiasis has been
reported at the Navy
MTFs. To prevent these illnesses, the Center of Disease Control have established
protocols that would maintain a safe and healthy swimming environment.
These protocols are primarily used to establish awareness and proper practices
for swimmers and disinfectors of pools (e.g. establishing
proper pH and chlorine levels to pools and hot tubs). The Navy and Marine
Corps Public Health Center also established their own protocols
on clearing a fecal infested pool.
Where there are no human
occupancy in swimming pools and public waters, animals may populated the area.
Thus animal fecal waste and bacteria can also strive in public waters and
marine water, being equivalent on harming humans.
Virginia like all states have their own
regulations to follow when it comes to disposing
pool water. First the water needs to be covered and second the normal
waiting period would be at least seven days for the chlorine and bromine to
evaporate, as well having a pH between 6 and 8. Improper disposal of pool water
may contribute to the decline of marine life because pool water is drained
directly into a pond, lake, stream, and/or sewage.
Giardiasis is a disease by human
and/or animal contribution. However, while we cannot fully control the latter,
we can control the former to prevent the spread of giardiasis.
