Background : Tuberculosis (TB) is a major public health problem in Bangladesh. The use of mass media is one of the important strategies in communicating behavioural change in relation to TB prevention and the treatment. However, most of the mass media public health interventions do not sufficiently engage the people. Due to this, truly little is known about the effects of locally instigated mass media promotion. Objective : To explore role of mass media on knowledge generation about Tuberculosis transmission in Bangladesh. Methods : This cross-sectional study was conducted among 180 adult persons(attendants of patients) of different socio-economic backgrounds attending the outpatient’s departments(OPD) of a tertiary care hospital. Purposive sampling was the process of selecting the subjects. Data were collected using one pretested semi-structured questionnaire through face-to-face interview. Results : A total180 respondents were interviewed. Mean age of the respondents was 28.75 ± 8.55 years. Majority of the respondents were graduate (29.0%).A total of 20.2% respondents had adequate knowledge about TB transmission without any misconceptions. Similarly, regarding the misconceptions on modes of TB transmission, 40.5% replied that TB transmits through utensils,57.6% respondents replied that TB transmits through sharing clothes/bed sheets/towel. About 28.3% respondents had the perception that the cost of TB treatment is high. Among the respondents30.5% had the false perception that it was necessary to go to big hospitals for TB treatment. Highest 140 (77.8%) respondents said television as the source of information in TB prevention. Friends/ relatives/ teachers, newspaper, radio, billboard etc. were the other sources. Twenty did not hear of TB prevention program. Conclusion : The mass media can be effective in getting messages about TB across to the community in developing countries. In this study we found that television, newspapers, and billboards were particularly useful tools for reaching out to them with specific campaigns regarding TB control.

In December 2019, a new human coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was discovered in Wuhan, China. Since then, the virus has spread over the world, affecting over 180 nations. SARS-CoV-2 has infected people of all ages, races, and genders, infecting both men and women and spreading at an alarming pace across communities. Given the virus's origin, much remains unknown; however, we do know that clinical presentations vary from a typical cold to more serious infections, including pneumonia, bronchitis, severe acute respiratory distress syndrome (ARDS), multi-organ failure, and even death. COVID-19 is thought to have a more fast and severe progression in people with underlying health issues or co-morbidities, frequently resulting in death. Methods: This retrospective study was conducted at Bangladesh's Tertiary care hospital. 534 patients were selected for this study. Medical history, age, gender, and co-morbidities (including Hypertension, Diabetes, and CKD, etc.) were recorded at the time of diagnosis, biochemical parameters such as CRP, ESR, creatinine, FBS, Hb, and LDH were also recorded. SARS-CoV-2 RNA was detected using a real-time reverse transcription-polymerase chain reaction (rRT-PCR) at diagnosis and throughout the follow-up of these patients. Results: The comorbid conditions, illness progression, and death rates in patients from a Bangladeshi tertiary care hospital were investigated in this study. COVID-19 patients with co-morbidities, such as hypertension or diabetes, are more likely to have a more severe course and development of the disease. Furthermore, individuals over the age of 60 who have co-morbidities and are infected have a higher incidence of admission to the intensive care unit (ICU) and death from the COVID-19. Conclusion: Where Vaccination, Early diagnosis, and Management lead to a better prognosis, patients with co-morbidities should take all steps to prevent contracting SARS CoV-2 since their prognosis is generally the poorest.
