Assessment of awareness and knowledge regarding HIV/AIDS among first year MBBS students in a Medical College in Maharashtra India

AIDS is a complex of illnesses caused by HIV. AIDS is the most advanced stage of HIV infection. According to recent reports by NACO, as many as 21.40 lac people are living with HIV (PLHIV) in India. Prevention of new HIV infections continues to be the mainstay of India’s national AIDS response. The lack of awareness and misconceptions about HIV/AIDS in the general population is mostly responsible for rapid spread of the disease and also with the social stigma attached with PLHIV in our country. Hence the present study was conducted to assess awareness regarding HIV/AIDS in newly admitted (First Year) medical students. Materials and Methods: This was a cross-sectional study done on 122 First Year MBBS students of Shri Bhausaheb Hire Govt. Medical College, Maharashtra. Data was collected by pretested questionnaires and analyzed using percentage. Results: All students (100%) mentioned unsafe sex and infected blood transfusion as a risk behavior. Most of the respondents believed HIV infection can be transmitted from: HIV infected pregnant woman to her baby (93%), breast feeding (62%), contaminated syringes, needles and razors (98%), tattooing (64%) and IV drug abuse (66%). Students were aware that it does not spread through wearing clothes of HIV-infected persons (92%), mosquito bite (77%), hugging and shaking hands with an infected person (97%), sharing common toilets (81%), sharing common utensils like plates, cups and spoons (84%), saliva (81%), contact with urine (48%) and feces (51%), coughing and sneezing (75%) and sharing a meal (93%). Awareness regarding prevention of HIV/AIDS was also found to be high with percentage of students responding for oral contraceptive pills (84%), IUCD (61%), condoms(98%), health education(99%), avoiding untested blood transfusion(100% boys and 95% girls), use of disposable syringe (85%), avoiding breastfeeding (44%) and use of latex gloves (41%). 82% of respondents are willing to assist with the delivery of a baby born to a mother with HIV/AIDS. All students believed that a separate educational programme for awareness and sensitization towards HIV/AIDS for people engaged in healthcare is needed. Conclusion: The present study shows that the medical students have somewhat better awareness and knowledge regarding HIV/AIDS than the general population. Still, there is a need for specific educational modules for imparting positive attitudes in medical students and healthcare providers in relation to people living with HIV/AIDS. © 2020 Published by Innovative Publication.

Introduction
AIDS, which is also known as Acquired Immunodeficiency Syndrome, is a complex of illnesses caused by a retrovirus known as human immunodeficiency virus (HIV). HIV destroys the CD4 T lymphocytes (CD4 cells) of the immune system, leaving the body vulnerable to life-threatening infections and cancers. Acquired immunodeficiency syndrome (AIDS) is the most advanced stage of HIV infection. To be diagnosed with AIDS, a person with HIV must have an AIDS-defining condition or have a CD4 count less than 200 cells/mm 3 (regardless of whether the person has an AIDS-defining condition). 1 According to an estimation by UNAIDS, since the first cases of HIV were reported more than 35 years ago, 78 million people have become infected with HIV and 35 million have died from AIDS-related illnesses. In 2018, there were 37.9 million [32.7 million-44.0 million] people living with HIV, out of which, 36.2 million [31.3 million-42.0 million] were adults and 1.7 million [1.3 million-2.2 million] were children (<15 years). 79% [67-92%] of all people living with HIV knew their HIV status. About 8.1 million people did not know that they were living with HIV. 2 This can be easily described as a pandemic of the modern world. India has also been affected by this global pandemic. According to recent reports by National AIDS Control Organization (NACO), there was an estimated 21.40 [15.90 -28.39] lac people living with HIV (PLHIV) in India. There was an adult (15- 3 pregnant women needed ART to prevent mother-to-child transmission of HIV. 4 Prevention of new HIV infections continues to be the mainstay of India's national AIDS response and has resulted in significant reductions in HIV incidence. HIV incidence per 1000 uninfected population is estimated to have declined from 0.64 in 1995 to 0.07 in 2017. However, the pace of decline in HIV incidence has been slow of late, dropping from 0.10 in 2010 to 0.07 in 2017. 4 The most common mode of HIV transmission in India is heterosexual and homosexual intercourse, with commercial sex workers, long distance truck drivers and migrant labour acting as the pool carrying virus from one place to other. An exceptions being North Eastern states where Intravenous (IV) drug abusers are common and the virus spreads due to their use of unsterile syringes and needles. Other less common modes of spread of infection are transfusion of blood and blood products and transplacental transmission. 5 The lack of awareness and misconceptions about HIV/AIDS in general population is mostly responsible for rapid spread and also with the social stigma attached with PLHIV in our country. Hence the present study was conducted to assess awareness regarding HIV/AIDS in First Year MBBS students. This opportunity was also used to educate and remove misconception about HIV/AIDS.

Materials and Methods
This was a cross-sectional study done on 122 First Year MBBS students of Shri Bhausaheb Hire Govt. Medical College, Maharashtra. All the students who were willing to participate were included in the study. Those who were not willing to participate were excluded from study. After taking their informed consent, total of 122 students present on the day of data collection were included in the study. Data was collected by pretested questionnaire and analyzed using percentages. All students (100%) mentioned unsafe sex and infected blood transfusion as a risk behavior. Most of the respondents believed HIV infection can be transmitted from: HIV infected pregnant woman to her baby (93%), breast feeding (62%), contaminated syringes, needles and razors (98%), tattooing (64%) and IV drug abuse (66%).
A number of students were also aware that people of age groups 15-29 years are at a higher risk of contracting HIV/AIDS than those of age group 5-15 years (80%), HIV/AIDS status can be confirmed by a blood test (70%), HIV/AIDS can be cured if diagnosed early(55%), treatment available(40%), HIV infected persons can stay asymptomatic for many months or even many years(96%).
HIV infected person should be isolated (13% boys and 5%girls), pre-marriage HIV testing should be done (98%), HIV positive couples can have children (60%), double gloves should be worn while treating HIV patients (29%), heat sterilization /autoclaving can kill HIV (20%), dental instruments should be washed with disinfectant every time after use (90%). 95% girls and 78% boys believed that doctors, nurses should be allowed to refuse to care for people with HIV/AIDS. 82% of respondents are willing to assist with the delivery of a baby born to a mother with HIV/AIDS. 98% of students did not agree when asked if they would not prefer to take care for patients with HIV/AIDS. 87% of them believed that it is necessary to take extra infection control precaution for patients with HIV/AIDS. 63% of the participants responded that refraining from multiple sex partners prevents HIV infection. All students believed that HIV/AIDS educational program is needed.
51% of the participants responded that patients of HIV/AIDS should be kept isolated and treated separately. Media (85.53% girls and 76.09% boys) was found to be the most common source of information regarding HIV/AIDS. Most (96% of the boys and 95% of the girls) of them knew that weight loss is a common symptom. 29% of the boys and 33% of the girls knew persistent diarrhoea as a symptom. 46% of the boys and 62% of the girls knew about persistent fever as a symptom.

Discussion
AIDS has become an important public health problem because of the complex emotional, behavioral and psychosocial complications that accompany the physical illness. The only way to combat a disease that has no effective treatment is by prevention. But due to the social stigmas, those suffering may avoid reaching the health centers for effective treatments. From the start of the AIDS epidemic stigma and discrimination have fuelled the transmission of HIV and have greatly increased the negative impact associated with the epidemic. HIV-related stigma and discrimination continue to be manifest in every country and region of the world creating major barriers to preventing further infection alleviating impact and providing adequate care support and treatment. 6 It was found in this study that all students (100%) had heard about HIV/AIDS, which is similar to the results of the study done by Samir O in Iraq, Biradar Orisatoki and Oguntibeju. 3,5,[7][8][9][10] In a study in Jordan in 2007 involving High School students, 84.9% of students had ever heard of HIV/ AIDS. (11) Malaysian young adults in a study done in 2008 were found to have an awareness level of 95.7% (12), whereas only 43% Nigerian adolescents were found to be aware of HIV in a study done in 2005. 11 This difference in the level of awareness may be attributed to various causes, like different age groups, different socioeconomic backgrounds and the difference in the time periods of the various studies, as people have now become more aware about various diseases including AIDS, higher penetration of Internet and mass-media may be one of the factors involved.
All the students were found to have correct knowledge of the causative agent which is similar to the studies by Biradar et al. and Ravi Shankar et al. 5,8 70% of the boys and 74% of the girls correctly answered that the infection is incurable which is less than the study conducted by Biradar et al. (97.2%).(4) However, Lal S et al. found in a study that only 45% knew that AIDS is not curable at present. 9 In our study all students (100%) knew about unsafe sexual contacts and infected blood transfusion as a risk factor for transmission of AIDS, whereas a study done by Goel N et al shows 98.94% of the students knew that HIV can be transmitted through blood transfusion while 97.89% of them knew that it could be transmitted through unsterilized needles and syringes. 12 This study also demonstrated level of beliefs and misconceptions among the students regarding HIV/AIDS, like transmission through hugging and shaking hands with an infected person (93% of the boys and 99% of the girls responded correctly), sharing common utensils like plates, cups and spoons (83% of the boys and 86% of the girls were correct), spread through mosquito-bites (89% of the boys and 70% of the girls were correct). A study on similar subjects from a Medical School on a Caribbean Island reported somewhat similar results. 13 In the study done by Shankar R et al., students believed that the infection was transmitted by sharing of clothes (75%), food or utensils (86%), kissing and shaking hands (89%) and by insect bites (39%). 8 In our study saliva was reported as a transmission route by 35%, which is similar to study conducted by Samant et al., where 34% of respondents reported similarly. 14 In another study comprising of 266 Health Care Workers from rural north India, a large proportion was not aware that, because of low viral load, saliva is not considered as a vehicle of HIV transmission, only 37.7% being correct in response. 15 19% of students reported availability of a vaccine to prevent HIV. 12% of the participants reported similarly in a study done by Samant et al. 14 About 88% of participants in the study by Biradar et al had correct knowledge about unavailability of vaccines to prevent HIV infection. 5 The present study revealed that the main sources of information about HIV/AIDS were the media (68.42% girls and 60.9% boys). These findings are in agreement with studies done in Iraq, Bangladesh and in India. 7,16 The second important source of HIV/AIDS information was doctors followed by teachers, family members (11.9% of the girls), friends and health workers, whereas study conducted by Samir et al shows similar findings, like teachers from school(49%), friends(43.7%) and family (parents/siblings) only30.4%. 7 Lal S et al reported comparable findings. 9 The high response to mass media as a source of information is better understood considering the impact that Internet and satellite television has had on India in the past decade. Similarly, in the study by Goel N et al., more than 60% of the students opined that TV is the best mode to impart awareness to the community followed by posters (90%), radio (78%), etc. 12 The current study showed that knowledge about HIV/AIDS was significantly associated with certain socio-demographic characteristics of students, and the results also showed that older and male students had higher level of knowledge about HIV/AIDS. The results of this study revealed that students having high socioeconomic status had more knowledge about HIV/AIDS and these associations were somewhat in agreement with the findings of a study by Lal S et al. in Kerala, India and by Tee Y et al. in Malaysia. 17 This may be due to higher degree of exposure to mass media including television, newspapers and internet of such students.
Concerning their attitudes toward HIV infected people, Kermode et al reported 23% of the health care workers preferred not to treat HIV infected patients. 15 Similar findings were reported by Kubde et al, where 34% of nursing students in New Delhi, India reported unwillingness to treat HIV infected people. 18 According to this study 95% girls and 78% boys believed that doctors and nurses should be allowed to refuse to care for people with HIV/AIDS. Several studies document the negative attitudes of Indian health professionals toward infected people. 10,15,18 In our study about 13% of boys and 5% of girls believed that patients with HIV/AIDS need to be nursed separately from other patients. Sixty six percent (66%) of females were comfortable having HIV infected doctors and nurses (coworkers) in clinics and hospitals compared to 36% of males. 44% of the medical students preferred not being friends with HIV infected individuals. In the study conducted by Choudhari S et al., 92% of respondents answered affirmative for quarantine. 10 98% of students believed that prior-marriage HIV testing should be done. 98% of respondents affirmed that use of condoms can prevent HIV/AIDS.

Conclusion
The present study shows that the medical students have somewhat better awareness and knowledge regarding HIV/AIDS than other groups when studied similarly. Still, there is a need of certain specific training modules for imparting positive attitude in medical students in relation to people living with HIV/AIDS. Role of media is undeniably huge in imparting proper knowledge and awareness, specially internet has to play important role.
