ABSTRACT
As we are probably aware of certain infectious diseases that transmit from body to body because of perspiration or respiration of air from a human being containing strains of the infection, the goal of this investigation is to see how the infection is getting spread from a human residing in a closed area provided with air conditioner and with an appropriate ventilation framework that need to be involved to diminish infection dissemination in this enclosed area. Considering the present COVID-19 situation, it is important to discover the effect of infection spread to an individual contagion source. An appropriate CFD-model giving analysis of infection transmission from individual to individual in an air-conditioned room would give results to understand such situations. Likewise, this examination would help in determining the velocity, temperature, and particle contours in a characterized walled area. Besides, we have displayed various nooks utilizing different ventilation frameworks to discover which framework would give better outcomes to decrease infection transmission. Our investigation would provide how varying flow rates in a room at an outlet could be effective in reducing virus dissemination, as this model could be applied to cafes, cinemas, inns, and above all emergency clinics where individuals remain in an enclosed air-conditioned room. © C.

ABSTRACT
OBJECTIVE: Hospitalized patients with COVID-19 are at high risk for anxiety and depression, but most studies about mental health during the pandemic included the general public, healthcare workers, and students. We aimed to explore the anxiety and depression levels, prevalence and predictors in patients hospitalized with COVID-19. METHODS: In this cross-sectional, exploratory study, sociodemographic and clinical features of 281 patients with confirmed COVID-19 were explored. Patients underwent a comprehensive psychiatric assessment and the Hospital Anxiety and Depression Scale (HADS) was administered through a telephonic interview. RESULTS: The mean age of the participants was 55.0⯱â¯14.9â¯years. One hundred forty-three (50.9%) patients were male, and 138 (49.1%) were female. Ninety-eight (34.9%) patients had significant levels of anxiety and 118 (42.0%) had significant levels of depression. Female gender, staying alone in a hospital room, early days of hospital stay, and any lifetime psychiatric disorder was associated with symptoms of anxiety. Being over 50â¯years of age, staying alone in a hospital room, and NSAID use before the week of hospital admission were associated with symptoms of depression. Anxiety and depression levels were lower when family members who tested positive for COVID-19 stayed in the same hospital room during treatment. CONCLUSION: Women, patients >50â¯years, patients who used NSAIDs before hospital admission, and those with lifetime psychiatric disorders may be at risk for anxiety and depressive symptoms in the COVID-19 ward. Allowing family members with COVID-19 to stay in the same hospital room may be associated with lower anxiety and depression levels.
