A series of cases of a novel virus causing respiratory infections in humans was observed in people of Wuhan, China, in December 2019. The disease caused by this novel virus was named as coronavirus disease 2019 (COVID-2019), This virus was isolated on January 7, 2020. It was morphologically similar to the virus that causes severe acute respiratory syndrome, or popularly known as SARS. However, the COVID-19 outbreak has surfaced as an imminent threat for the public health and has posed as a critical challenge for research and medical communities.^{Reference Fauci, Lane and Redfield1}

Broad steps to minimize human-to-human transmission of COVID-19 is required to control the current outbreak. Special efforts and attention to protect or decrease transmission should be applied in populations with high susceptibilities, such as health-care providers and elderly people. The early death cases of COVID-19 outbreak occurred in the elderly due to a compromised immune system that allows for a rapid progression of viral infection. The public services and facilities should provide decontaminating reagents for cleaning hands on a routine basis. Physical contact with wet and contaminated objects should be dealt cautiously, especially agents such as fecal and urine samples that can potentially serve as an alternative route of transmission. Epidemiological changes in COVID-19 infection should be monitored, keeping in mind the potential routes of transmission and subclinical infection, along with the adaptation, evolution, and virus spread among humans and possible intermediate animals and reservoirs. There remains a considerable number of questions that need to be addressed.^{Reference Rothan and Byrareddy2}

Various bodies including the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) have issued advice on preventing further spread of COVID-19. They recommend avoiding travel to high-risk areas and contact with individuals who are symptomatic from regions with known COVID-19 outbreak. Basic hand hygiene measures are also recommended, including frequent hand washing and the use of personal protective equipment (PPE), such as face masks for people showing symptoms. It is also our responsibility to be aware of the signs and symptoms and to promptly address them.^{Reference Sohrabi, Alsafi and O’Neill3} Comprehensive protective measures, such as face mask and hand hygiene are included in public health guidelines for pandemic preparedness. Most coronaviruses, including COVID-19, can be inactivated by alcohol-based hand sanitizers and disinfectants, such as bleach. Environmental disinfection using appropriate sanitizers is also recommended. Because hand hygiene does not affect the direct transmission of COVID-19 by respiratory droplets, face masks have been widely used by at-risk populations in China and some other locations in Asia, such as Taiwan and Hong Kong. The efficacy of face masks among healthy individuals is questionable, but masks can protect others, particularly health-care workers, from active symptomatic individuals with COVID-19. The combination of masks and hand hygiene, however, has been shown to reduce transmission of respiratory viruses. Face mask use should be recommended for infected persons, for uninfected persons who are caring for infected persons, and for those interacting in extensive crowded settings where widespread community transmission is possibly occurring.^{Reference Cowling and Aiello4}

In India, it has been found that some patients fled the hospital wards when they were asked to stay under quarantine. This comes as no surprise as health facilities in India are not as efficient as they are expected to be to fight the rapid spread of COVID-19. As per World Bank, India only spends 1.28% of the gross domestic product on health facilities. This underdeveloped infrastructure of health could be catastrophic at times of health emergencies, such as COVID-19.^{Reference Danival5}

Hence, the people of India need to be aware of the basic modes of prevention and other necessary precautionary measures that can diminish the spread of the infection. Our present study was carried out among the undergraduate students of Mangalore to assess the awareness regarding spread and control of this novel malady.

METHODS

The study included 868 undergraduate college students belonging to 2 university colleges in Mangalore in coastal South India from varying socio-economic status. A lottery method was used to select these 2 colleges of 7 university colleges of Mangalore city. Prior permission from Principal of the concerned colleges were taken. Young adults in the age group of 18-23 y were included in the study sample.

Before commencement of the study, clearance from the Institutional Ethics Committee was obtained, and consent from each person was documented to ensure their voluntary and active participation in the study (Protocol No. 20030).

Sample Size

The sample size for a finite population considering 5% of 4600 population, confidence level 99 and confidence interval 0.01.

$${\rm{SS}}({\rm{sample}}\,{\rm{size}}) = {{[{z^2}p(1 - p)]} \over {{c^2}}}$$

$${\rm{SS}} = {{{{(2.58)}^2}(0.05)(1 - 0.05)} \over {0.01}} = 474$$

The questionnaire consisted of 12 questions regarding COVID-19 and was prepared by the authors. The content and construct validity were checked with 4 subject experts. The questionnaire (Table 1) was circulated by means of Google docs among the study participants, and the data were collected during a 1-wk period. The Google doc had 2 parts. In the first part, participant had to consent only then they could access the second part of questions. The link was sent to 500 undergraduate students belonging to 2 university colleges of Mangalore in coastal South India. A total of 868 students responded and filled out the questionnaire. This may be due to the sharing of the link among their friends. All the 868 responses were considered in this study. The data obtained from the study were compiled and statistically analyzed using SPSS software version 20. Upon completion and submission of the questionnaire, relevant information, especially on the importance of hand washing, wearing masks, and social distancing to prevent COVID-19 infection, was sent to the volunteers by means of e-mail.
