Background: Surveillance is the backbone for effective public health practice. Traditionally, surveillance system relies on the collection of information regarding health-related events through healthcare facilities, disease notification system from the physician, syndromic notification networks, selected sentinel healthcare facilities, or by event-based data. However, there are several limitations in using conventional surveillance.  Methods: With the advancement of technology and computer science, overcoming those limitations and complementing the traditional method has been recommended. Three leading emerging technologies are applied in public health surveillance: the internet of things, artificial intelligence, and blockchain.  Results: Application of informatics in public health surveillance could raise several issues including accessibility and affordability of innovations; public health informatics’ experts, law, and regulation to protect patients’ information; social and ethical considerations, norms, and standards of implementing new technologies; data ownership; privacy and sharing of information; biosecurity; biosafety; and cybersecurity.  Conclusion: This article aimed to review several applications of informatics system in public health surveillance practice and its several issues related to the use of technology. Several applications of informatics could be useful for incoming challenges in public health. However, application of informatics can pose significant issues and must be taken into consideration in public health practice.

Colorectal cancer mortality also ranked second after lung cancer (World Health Organization, 2020). Even though there is a high number of diagnosed cases and death, the 5-year survival rate was still high in Korea and Australia, which was more than 70%, meanwhile in Singapore, Japan, Italy, Belgium and some other countries was 60-69%. Countries that had less than 50% of survival were

SARS-CoV-2 virus created a huge health impact due to isolation, quarantine, or lockdown. University students also affected with the closure of institute and switch in teaching methods. The objective of this study is to explore the health-related lifestyle changes among university students during the implementation of movement control order. Secondly, we aimed to convoke suggestions and recommendations to promote healthy living amidst university students. This study implemented qualitative method via using a semi-structured interview. Three focus group discussions were conducted consisting of 12 participants recruited from snowball sampling method. Utilizing verbatim transcription approach, an inductive thematic point was sketch for data analysis. Seven male and five female students with a mean age of 20 ± 1.3 years (range 19-23) were recruited into this study. Four themes identified from the interview. Physical health influence by administrative roles to physically inactive and less sport activity. Secondly, mental health concern towards mixed emotions, coping strategy, psychological adjustment, and mental health issues. Variation and self-prepare food, food supply, dietary habit and dietary pattern contribute to changes in food intake. Student lifestyles modulate to sleep hygiene, alcohol consumption, online classes problem, individual factors, and other unhealthy activities. Some students experience no difference in the surrounding transformation. During the pandemic, students experienced health related-behavioural changes involving physical health, mental health, dietary and lifestyle. Even though some informants perceived no changes in certain aspect, they still experience health-related behavioural changes in other aspect linked to health.
