batia? >> dr. batia from the department of health. my apologies for being late. the department's responsibility for control of bed bugs falls into four categories. prevention and education, enforcement, regulation of pesticide use, and the operations of certain hotels. i think it is important to know that bed bugs can spread from place to place on people and their belongings. that makes it very hard to control. it is important to note that they are not vectors of human disease. they do not carry disease. they in fact a person. they create symptoms in a person, but they do not carry disease. it is important to know that no public agency in the city, state, or country collects surveillance information on bed bugs. we do not know what the prevalence of infestation is in the city, state, or country. the limited information we do know is from day that we get on complaints the complaint data will reflect only a fraction of the true problem and burden of bed bugs in society. we do not collect surveillance data on bed bugs because they are not a factor of human disease.
