Typhoid fever, a common enteric disease in Pakistan, caused by Salmonella typhi, is becoming an extended drug-resistant organism and is preventable through the typhoid conjugate vaccine (TCV). Public adherence to preventive measures is influenced by knowledge and attitude toward the vaccine. This study investigates the knowledge, attitudes, and practices of the general population of Pakistan toward TCV. The differences in mean scores and factors associated with typhoid conjugate vaccine knowledge, attitudes, and practices were investigated. A total of 918 responses were received with a mean age of 25.9 ± 9.6, 51% were women, and 59.6% had graduation-level education. The majority of them responded that vaccines prevent illness (85.3%) and decrease mortality and disability (92.6%), and typhoid could be prevented by vaccination (86.7%). In total, 77.7 and 80.8% considered TCV safe and effective, respectively. Of 389 participants with children, 53.47% had vaccinated children, according to the extended program on immunization (EPI). Higher family income has a higher odds ratio (OR) for willingness toward booster dose of TCV [crude odds ratio (COR) = 4.920, p–value <0.01; adjusted odds ratio (aOR) = 2.853, value of p <0.001], and negative attitude regarding the protective effect of TCV has less willingness toward the booster dose with statistical significance (COR = 0.388, value of p = 0.017; aOR = 0.198, value of p = 0.011). The general population of Pakistan had a good level of knowledge about the benefits of TCV, and attitude and practices are in favor of the usage of TCV. However, a few religious misconceptions are prevalent in public requiring the efforts to overcome them to promote the usage of vaccines to prevent the disease and antibiotic resistance.

The study was conducted to determine bacterial contamination of stethoscopes used by doctors before and after disinfecting with isopropyl alcohol and analyze their practices of disinfecting stethoscopes. Samples from stethoscopes were taken before and after disinfecting with 70% isopropyl alcohol swab with the help of a sterile swab. All swabs were inoculated on Blood and MacConkey agar plates and were examined for growth. Stethoscopes of 78 doctors were sampled which included 45 (58%) males and 33 (42%) females. Before decontamination of diaphragms with isopropyl alcohol, 27 (34.6%) diaphragms had “growth” while 51 (65.4%) had “no growth.” After decontamination with isopropyl alcohol, 5 (6.4%) had “growth” while 73 (93.6%) had “no growth.” The most common microorganism isolated from stethoscopes’ diaphragms was methicillin-resistant Staphylococcus epidermidis (MRSE), that is, 14 out of 78 (17.9%). The survey also evaluated factors associated with contamination of stethoscopes. Most doctors 71(91%) believe that stethoscopes can be a source of infection and 55.1% (N = 43) responded that both diaphragm and bell of stethoscopes can transmit infections. Many doctors (41%, N = 32) reported that “forgetfulness/laziness” was the barrier which they faced regarding stethoscope hygiene followed by “lack of time” (21.8%, N = 17). The contamination rate (66.6%) is highest in those doctors who are using their stethoscopes for 3–5 years. Of them, 30 doctors (38.5%) never decontaminated their stethoscopes among which 17 had growth in their stethoscopes before cleaning with isopropyl alcohol, while three had growth even after decontamination. Most doctors used sanitizer (29.5%) and isopropyl alcohol (25.6%) as cleaning agents.
