BACKGROUND OF THE PROBLEM
Leptospirosis is one of the deadliest bacterial infection that I commonly acquired in tropical countries. you can get the disease when you were exposed to soils and waters that is contaminated by leptospira bacteria.
Rodents such as rats are the primary carriers of the leptospirosis bacteria. It is important to identify the signs of rodent infestation at home. If you regularly see rodent droppings around food packages, in drawers, cupboards, under the sink, then your house is infested. Whenever you see such droppings or boxes of food, or wirings that has rodent bites, you must take an action.
Symptoms can take 2 - 26 days (average 10 days) to develop this may include: dry cough, fever, headache, muscle pain, nausea, vomiting, and diarrhea, shaking chills, less common symptoms include: abdominal pain, abnormal lung sounds, bone pain, conjunctivitis, enlarged lymph glands, enlarged spleen or liver, joint aches, muscle rigidity, muscle tenderness, skin rash and sore throat. (Dugdale III, 2010) Test to be done to find if you contract leptospirosis are the following: CBC (Complete blood count), creatine kinase, urinalysis. Medications are given to the patient but complicated cases however are life-threatening if not treated promptly. The fatality rate of the disease is 5-40. (Dugdale III, 2010) Here in the Philippines one of the most common cause of leptospirosis is flood water. Leptospirosis cases goes up in the rainy period. In Metro Manila, improper disposal of our wastes such as plastics, domestic wastes, and others blocks the water pass on the sink or to the drainage system. This causes floods even in just a small amount of rain. And garbage attracts rodents that carry a letpospira bacteria and it contaminates the flood water that leads to acquiring the leptospirosis.
1.2. Background of the study
Flash floods are common throughout the Philippine archipelago during the monsoon seasons, which runs from the June to December. They are particularly common in Manila, the country’s sprawling capital and home of 14 million Filipino’s. The awareness of the people is very much important especially when flash floods or typhoons occur. Leptospirosis is a bacterial disease which could be contracted by humans when exposed to flood waters containing urine infected animals like rats, dog, and pigs. The leptospirosis cases was caused by the widespread flooding caused by the typhoons that affected the Luzon areas. In Quezon City one barangay, barangay Gulod, has encountered many cases of leptospirosis. Barangay Gulod is located near the Tullahan River and Kaybuktot Creek. The barangay itself is along the Quirino Highway. The barangay is big but because of poor urban development program the drainage system is still a problem during the rainy seasons they have the most number of incidents of leptospirosis cases in the past 3 years. In 2009 the disease, according to the record of Department of Health (DOH) has afflicted more people in Metro Manila, attributing the “Outbreak” to large numbers of people wading in flood waters carrying the bacteria. The DOH had recorded 1,027 leptospirosis patients, wherein 89 died. There were 122 cases in Quezon City alone with 14 cases in Barangay Gulod. (Quezon City Health Department [QCHD], 2011)
In 2010, leptospirosis was noted as the fourth on the list of the top disease outbreaks in the Philippines. The DOH has recorded over 400 leptospirosis cases in the first half of the year (Department of Health [DOH], 2010), which includes 26 deaths with 1 case in Barangay Gulod. (QCHD, 2010)
Recently, the Department of Health released an announcement that casualties from leptospirosis has increased 247% in 10 months (January-October) in Metro Manila with number of 131 cases of Leptospirosis in Quezon City with 5 cases in barangay Gulod. It usually takes two weeks after the infection to manifest flu-like symptoms. If not diagnosed early...
