The document discusses screening for dengue hemorrhagic fever (DBD) conducted at the North Banjarbaru Health Center in South Kalimantan. It found an average of 145 DBD cases per month from January to May 2016. Screening is done to classify people into categories of likely or unlikely to develop the disease. Proper sanitation and hygiene can help prevent transmission, as environmental conditions and human behavior influence disease spread. Maintaining a clean living environment, especially around water sources, can reduce the risk of dengue.
