Background: Disease surveillance is one of the major components to combat against infectious diseases. As health-care professionals are indispensable to mandatory notifiable disease surveillance, their knowledge and attitudes toward infectious disease notification played an important role for timely and effective reporting to the surveillance system. Therefore, we aimed to determine the knowledge of mandatory notifiable infectious diseases in Malaysia and attitude towards infectious disease reporting among final year medical students. Methods: A cross-sectional study was conducted from May to June 2017 in the private medical college in Malaysia. Materials and Methods: We purposively selected the final year (semester 10) medical students and a total of 124 students participated in this study. We collected data using a self-administered, structured questionnaire. Data were analyzed using descriptive statistics, independent t-test, and one-way analysis of variance. Results: Among the final year medical students, 47.5% had moderate knowledge but 4.2% had good knowledge of mandatory infectious disease notification. Only 3.2% of the students correctly answered all the notifiable diseases listed in the questionnaire. Most of the students had positive attitude toward communicable diseases reporting, rewards, and penalty for notification. There was no significant relationship between sociodemographic characteristics and knowledge and attitude of infectious disease notification. Conclusions: The majority of the final year medical students had moderate level of knowledge and positive attitude of infectious disease notification; however, there were some deficiencies. Better instruction and training on infectious disease notification procedures of Malaysia should be provided to the final year medical students which could not only reduce underreporting but also improve timely and effective reporting in future.

| Introduction|| |
Disease surveillance is one of the major components to combat against infectious diseases and is important for early detection of outbreaks and effective control of the spread of the communicable diseases. There are several infectious disease surveillance systems in Malaysia such as mandatory notifiable diseases surveillance, laboratory surveillance, clinical-based surveillance, community-based surveillance, and surveillance by other agencies which include the Department of Veterinary Services and Foreign Workers Medical Examination Monitoring Agency. Among these systems, the mandatory notifiable diseases surveillance involves statutory notification of 26 infectious diseases under prevention and Control of Infectious Diseases Act 1988., This system requires health professionals from multidisciplines in government and nongovernment health facilities to report cases of notifiable infectious diseases to the district health authorities when the clinical diagnosis is made.
Even though notification and reporting of infectious diseases are vital in prevention and control of the spread of infection, underreporting, and incompleteness of notifiable infectious disease were documented in many countries.,,,,,,, Many studies have shown that major barriers to reporting include the health professional's knowledge of notifiable diseases ,,,,,,,,,,,,, and attitude toward infectious diseases reporting.,, Learning on disease surveillance at undergraduate level provides the knowledge and attitude which is essential to fulfil the future role in country's disease surveillance system. In our college, lectures on communicable diseases surveillance and outbreak investigation were given to the students during the 3rd year of the medical curriculum. The aim of these lectures is to introduce principles and functions of communicable diseases surveillance, mandatory notification and reporting, surveillance mechanisms in Malaysia, and principles of an outbreak investigation. However, knowledge on Malaysia's infectious disease surveillance system by medical students and their attitude toward infectious disease notification has never been evaluated before their graduation from medical college. To the best of our knowledge, there is limited information regard to this topic among medical students. Therefore, we conducted this study to determine knowledge of mandatory notifiable infectious diseases in Malaysia and attitude toward infectious disease reporting among final year medical students.
| Materials and Methods|| |
We conducted a cross-sectional study among final year (semester 10) medical students in the private medical college in Malaysia from May to June 2017. There were 150 students attending final year at the time of our study. The sample size was calculated using the formula for single population proportion with the margin of error 5%, the assumption of 95% confidence level, and 89.8% of awareness on disease surveillance and notification. The minimum sample size required was 141. Therefore, we employed purposive sampling and invited all students who were attending final year to participate. A total of 124 students provided written informed consent, and they were included in this study.
Three authors (HHKS, NNT, and HL) distributed the questionnaire to the final year students during their clinical posting. Before data collection, the purpose of the study was explained to the respondents. Participation was strictly voluntary, and autonomy of the respondents was respected. Written informed consent was taken from each participant. We used self-administered method for data collection, and the students were given instruction if they agreed to participate in this study.
We used the structured questionnaire and collected knowledge and attitude of infectious diseases notification, and sociodemographic characteristics including age, gender, ethnicity, nationality, and scholarship status. Knowledge refers to the medical student's ability to answer about mandatory infectious disease surveillance and notifiable diseases in Malaysia. We defined attitude as the medical student's opinion of agreement or disagreement to the statement concerning communicable diseases reporting. In knowledge part of the questionnaire, we included twelve multiple choice and true/false questions about infectious disease surveillance. We listed 18 infectious diseases in which thirteen were correct answer of notifiable diseases required by law. We also listed 12 diseases for notification by phone within 24 h and nine of 12 diseases were notifiable within 24 h in Malaysia. The respondents were asked to choose whether the disease was notifiable, not notifiable, or dont know. We scored one mark for the correct answer and score zero mark for the wrong answer. The maximum possible score for knowledge was 44 and the minimum was zero. Regards to the attitude of infectious disease reporting, we adopted and modified the questionnaire used in the previous study. As English is the language of instruction in our college, we did not translate the original English questionnaire to local language. We included 16 items including nine positive and seven negative statements, and five-point Likert scale (strongly agree, agree, neutral, disagree, and strongly disagree) was used. For positive items, strongly agree was scored five and strongly disagree was scored one while for negative items, strongly agree was scored one, and strongly disagree was scored five. The maximum possible score for attitude was 80 and the minimum was 16.
We carried out a pilot study with convenience sample to check for reliability, clarity, and understanding of the questionnaire. Content validity was checked with eight experts, and face validity was checked for clarity and understanding of the questionnaire. The Cronbach's alpha coefficient of knowledge questions was 0.479 and attitude questions were 0.533.
After checking and coding the questionnaire, we used SPSS version 12 (SPSS Inc., Chicago, IL, USA) for data entry and data analysis. Two authors (MNNH and KLP) entered data and two authors (HHKS and ALB) analyzed the data. Regards to knowledge and attitude, the total score was computed by taking the sum for all of the items (higher score indicates better knowledge and attitude). We categorized knowledge and attitude into three levels such as good (>80% of the maximum possible total score), moderate (60%–80% of the maximum possible total score), and low (<60% of the maximum possible total score).
For quantitative variables, mean and standard deviation (SD) were calculated and for categorical variables, frequency, and percentage were described. We used Independent t-test and one-way analysis of variance to determine the relationship between sociodemographic characteristics and knowledge and attitude of infectious diseases reporting. All the statistical tests were two-sided, and the level of significance was set at 0.05.
In our study, confidentiality was maintained, and anonymity of respondents was ensured. In addition, data were kept secured and available only to the statistician. This study was approved by Research Ethics Committee of our college.
| Results|| |
A total of 124 final year medical students participated in this study, and the response rate was 82.67%. The mean age was 25.01 years (SD 0.77) and 62.9% of the students were female. 36.3% of them were Malay while 24.2% were Chinese and 28.2% were Indian. Majority of the participants (96.8%) were Malaysian nationality while only four students (3.2%) were from foreign countries. About half of the students (50.8%) received scholarship while 48.2% were self-funded. [Table 1] also shows the knowledge and attitude of infectious disease reporting with respects to sociodemographic characteristics. There was no significant difference of knowledge and attitude of mandatory infectious disease reporting between different genders, races, nationalities, and scholarship status [Table 1].

[Table 2] shows the knowledge and attitude of mandatory infectious disease surveillance and reporting among students. Nearly 47.5% of the students had moderate knowledge and 48.3% had low knowledge while only few of them (4.2%) had good knowledge. However, the majority of the students (83.3%) had moderate attitude and 10.8% had good attitude while only 5.8% had low attitude. Majority of the students (92.7%) were aware of mandatory surveillance for infectious diseases in Malaysia and 81.5% of them correctly respond about the objective of country's surveillance system. Only 3.2% and 5.6% of the students correctly answered all of the mandatory notifiable diseases and diseases to be reported within 24 h from the list given. Most of the students were able to identify the notifiable diseases, but only 25% and 32.3% knew tetanus, and food poisoning should be reported. Regards to the notifiable diseases within 24 h after diagnosis, about half of the students were correct for most of the diseases listed such as cholera, dengue, diphtheria, plague, and poliomyelitis while 74.2% correctly identified Ebola. However, only 28.2% and 29.8% of the students knew food poisoning and yellow fever should be reported within 24 h after diagnosis [Table 2].

Most of the students had positive attitude toward communicable diseases reporting, rewards, and penalty for notification. Nearly 61% of them agreed that they will report after laboratory confirmation. About one-third of the students agreed that reporting without patient's consent will violate patient's privacy, and 21.3% agreed, and 29.5% were neutral to the statement that reporting will violate doctor–patient confidentiality. Majority of the students (46.3% strongly agreed, and 31.7% agreed) agreed that infectious disease notification has been an important emphasis in medical training [Table 3].

| Discussion|| |
We conducted this cross-sectional study to determine knowledge of mandatory notifiable infectious diseases and attitude toward infectious disease notification among final year medical students.
Knowledge of mandatory infectious disease notification
We found that 92.7% of the final year students were aware of mandatory surveillance for infectious diseases in Malaysia, and 81.5% of them correctly respond to the objective of country's surveillance system. Similar to our finding, previous studies done among health professionals in Nigeria, Germany, and England showed that the percentage of awareness of the physician's duty for disease notification was as high as 87%–97%.,, Regards to the overall knowledge of infectious disease reporting, even among general practitioners and physicians, the good level of knowledge was ranged from 14.3% to 37%., Among the final year students in this study, 47.5% had moderate knowledge, but only 4.2% of them had good level of knowledge which was lower than previous studies., There were also deficiencies regards to the knowledge of notifiable diseases and infectious diseases to be reported within 24 h after diagnosis as very few students correctly identified all of the notifiable diseases listed. Moreover, only 25% and 32.3% of the students knew tetanus and food poisoning were notifiable diseases. Regards to the notifiable diseases within 24 h after diagnosis, more than half of the students were correct for cholera, dengue, diphtheria, poliomyelitis, and Ebola, but only 39.5%, 28.2%, and 29.8% of the students knew rabies, food poisoning, and yellow fever should be reported within 24 h after diagnosis. Previous studies conducted among doctors and healthcare personnel in Taiwan, United States, England and Wales, and Nigeria also revealed that the doctors failed to know the notifiable diseases which included the diseases that required immediate reporting as well as reporting within 7 days after clinical diagnosis.,,, The study which was done in Nigeria by Aniwada and Obionu showed that <30% of primary health-care workers in private sector had correct knowledge of reportable diseases and reporting procedures while this was 50%–60% in public sector. It was well documented that lack of awareness of notifiable diseases is associated with underreporting.,,,,, Knowledge of notification requirements and procedures was correlated not only with time and frequency reporting but also with active reporting partnership for the surveillance system. Although there was the good level of awareness for mandatory notification system among final year medical students in this study, knowledge of notifiable diseases was needed to be improved. Training about surveillance and disease notification have shown not only to improve health-care provider's knowledge and attitude of mandatory infectious diseases notification but also to have an impact on effective reporting for surveillance systems.,
Attitude toward infectious disease notification and reporting
Physician's attitude toward infectious disease reporting also played an important role in timely and effective reporting. The study done by Pacheco et al. showed that physician's attitude relating notification significantly increased the odds of reporting the notifiable disease. In our study, the majority of the students (83.3%) had moderate attitude and 10.8% had the good level of attitude toward infectious diseases notification. Similar to the research conducted among Korean physicians by Kim et al., most of the students in this study had the positive attitude for communicable diseases reporting, rewards, and penalty for notification. Furthermore, the response rate was high as 82.67% in our study that showed the interest and willingness of final year medical students regards to this topic. About one-third of the students agreed that reporting without patient's consent will violate patient's privacy and violate doctor–patient confidentiality. Moreover, 61% of them agreed that they only report after laboratory confirmation. According to standard reporting procedure in Malaysia, notifiable infectious cases should be reported based on clinical diagnosis regardless of laboratory confirmation. If the results are not conclusive or presence of missing data, the cases may be reported as a probable or suspected. It had been shown that the belief of notification after laboratory confirmation and violating patient's privacy was associated with underreporting of mandatory notifiable diseases.,
Relationship between sociodemographic characteristics and knowledge and attitude toward infectious disease notification
Studies had revealed the knowledge and attitude of infectious diseases reporting with respects to sociodemographic characteristics such as gender, races, specialties,, years of experiences, and geographical regions. Our study revealed that knowledge and attitude of infectious disease reporting were not significantly different between genders, races, nationalities, and scholarship status among final year medical students which were similar to the findings of study done among physicians.
Majority of the students in our study mentioned that infectious disease notification has been an important emphasis in their medical training. Although training during residency and continuing medical education provided the knowledge about disease reporting, most of the trained physicians received this knowledge during medical school. It was also found that the physicians who had received training on reporting were more knowledgeable of diseases for immediate reporting and notification procedures , which also had a positive effect on reporting practices.
Limitations of the study
Although the response rate was high as 82.67%, our study has some limitations. The participants may respond differently to some of the attitude questions due to social desirability. This study was conducted in one private medical college; therefore, the findings cannot be generalizable to other medical institutions. This was a cross-sectional study; hence, we could neither observe the changes in the student's knowledge and attitude over time nor inference of causality. Since the study had been conducted among medical students, we were not able to measure the reporting practice and the barriers to the mandatory infectious disease notification.
Future directions of the study
This study highlighted the needs of training on infectious disease notification procedures among medical students. Case definitions and the list of notifiable diseases that need immediate reporting as well as notification within 7 days after clinical diagnosis should be emphasized. Moreover, future research should explore knowledge and attitudes of mandatory infectious diseases notification, the reporting practice, and the barriers to notification among practitioners in Malaysia.
| Conclusions|| |
The majority of the final year medical students had the moderate level of knowledge and positive attitude of mandatory infectious disease notification though there were some deficiencies. Providing awareness training about infectious disease notification and procedures while in final year may modify the medical student's knowledge and attitude toward infectious disease notification. This would not only be beneficial and help to reduce the underreporting and incompleteness in future but also fulfill the future role in country's disease surveillance system.
The authors would like to acknowledge to all final year (semester 10) students who participated in this study. We also would like to thank the management of Melaka-Manipal Medical College (MMMC) and Research Ethics Committee (MMMC) to grant the approval for this study.
