Objective: The study was carried out to determine the knowledge, believe and practice of students about insects for forthcoming research due to tropical medicine. Its application to tropical medicine is acceptable. Methods: The study was conducted among 300 students by pre-trained interviewers using a pre-test questionnaire in secondary, high school, and university in the Tehran city from June 2008 to May 2009. All statistics analysis was carried out the spss ver 11.5 EPI6, stata 80, chi-square and fisher exact test. Results: Significantly, 82.3% of the interviewers had problem when expose to insects (P<0.05). Domestic animals and unhygienic human habitant most importantly incriminate to present of insects. Out of 73.8% of the respondents believed the association between entomophobia and human habitat. Entomophobia was significantly associated with density and size of insects (P<0.05). Out of 37% of the respondents agree with killing of insects pest (P<0.05). Significantly steers was the common sign of entomophobia among the respondents (P<0.05). Out of %49.7 of audiences belived to association between entomophobia and age.Conclusion: In conclusion important the education and communication messages against entomophobia take in to consideration the local practice.

Rationale: Rabies, as an acute viral disease of the mammal's central nervous system (CNS), with a high mortality rate, is transmitted to humans through the bite of a rabid animals, especially canine and feline. Patient concerns: An Afghan man, aged 50 years was bitten by a fox in a farm around the Qom-Tehran road, Central Iran in 2018. The patient visited the doctor after the bite, however the period between incidence and hospital visit was not established and no indication was given whether the bite site injury was thoroughly washed. The patient was neither referred to the health center for vaccination (post-exposure prophylaxis) nor an effective therapeutic measures was applied. Forty-five days post-exposure, the patient presented with symptoms such as headache, fever, tingling and burning sensation and was referred to the Centers for Disease Control and Prevention (CDC) unit of Qom Provincial Health Center. Diagnosis: Rabies infection. Interventions: Forty-five days after the animal bite, in CDC of Qom Health Center, he received rabies post-exposure prophylaxis treatment was referred to an infectious diseases physician. Based on the history of animal bites, the patient was classified as probable case of rabies. The clinical symptoms of rabies appeared in patient after hospitalization. Outcomes: Ultimately the patient died in hospital 4 days after hospitalization (50 days after the occurrence of animal bite). After referring the patient to the CDC, the patient's saliva (0.5-1 mL) was sampled three times every 3-6 hours and tested by PCR. Human rabies was confirmed by Department of Virology in the Pasteur Institute of Iran. Lessons: Physicians and clinicians have responsibilities to be critical in observations and take prompt actions in case of animal bites, as rabies usually develops within 7 to 14 days, and delayed intervention after the onset of symptoms, vaccine and serum injections cannot lead to the survival of the patient.
