Objective:Effective handwashing practices help prevent the spread of coronavirus disease 2019 (COVID-19). This study examined the knowledge, frequency, and characteristics of handwashing practices among Vietnamese university students.Methods:An analytic cross-sectional study was conducted on all students enrolling at Phenikaa University in Vietnam. A self-developed questionnaire was used to collect information on the participants’ knowledge regarding the effectiveness of handwashing as a COVID-19 preventive measure, the moments for hand hygiene, the most appropriate practices in different situations, and frequency.Results:Among 728 study participants, 460 (63.2%) were from health-related faculties. Almost (97.9%; 713/728) all participants knew that handwashing could protect against the spread of infection, but less than half performed handwashing often in a normal day (47.4%; 345/728), after sneezing or coughing (48.9%; 356/728), and 7.4% (54/728) only washed hands when hands are visibly dirty. Health students used alcohol-based handrub in all situations, including those requiring handwashing with water and soap (P < 0.05).Conclusions:The levels of knowledge regarding the effectiveness of handwashing among study participants are high, but actual practices of handwashing are suboptimal. It is crucial to improve community education to help reinforce correct hand hygiene behaviors, including when to wash hands and which method should be used.

Although Vietnam has been successful in the fight against the first wave of COVID-19, domestic outbreaks have continued to occur. Given university students constitute a significant proportion of the population in Vietnam, to improve the prevention and control of COVID-19 in Vietnam and comparable countries, we examined their knowledge, attitude, and practice (KAP) towards face mask use which is an important preventive measure and the association between the levels of COVID-19 knowledge and KAP towards face mask use. A cross-sectional survey was conducted on all students studying at Phenikaa University, Hanoi, using a self-developed questionnaire consisted of 42 questions regarding KAP towards face mask use as well as reuse of cloth mask, and COVID-19 knowledge. Among 728 participants, 40.9% (298/728) were male, 63.2% (460/728) were from health-related faculties, 46% (335/728) lived in urban areas, and 51.9% (378) had good levels of COVID-19 knowledge. Regarding face mask, most (89.7%, 653/728) participants had good knowledge scores, 72.8% (530/728) had positive attitudes, and 76.5% (557/728) had good practice scores. The most common types of masks used were surgical mask (57.6%, 419/728), followed by non-antibacterial cloth mask (23.1%, 168/728). Among 168 participants using non-antibacterial cloth mask, 43.5% reused masks (73/168), of whom 6.8% (5/73) did not wash their masks at least daily. Face mask use knowledge was statistically associated with COVID-19 knowledge (P

Background: Vietnam is among the few countries that were successful in the fight against the first wave of coronavirus disease 2019 (COVID-19) However, subsequent domestic outbreaks of COVID-19 continue to occur To sharp the community education program to guarantee the final success in the fight against COVID-19 in Vietnam and comparable countries, we examined the levels of COVID-19 knowledge and associated predictors among university students in Vietnam Materials and Methods: A cross-sectional study was conducted on all students enrolling at Phenikaa University using a self-developed questionnaire consisted of 20 questions regarding COVID-19's risk factors, transmission routes, symptoms, and prevention Results: Among 728 participants, 40 9% were male, 63 2% studied health-related majors, and 18 1% lived alone Correct response rates ranged from 25 3% to 98 9% across 20 questions Only 51 9% (378/728) of participants had good knowledge levels Studying health majors (adjusted odds ratio [AOR] 0 547, 95% confidence interval [CI] 0 398 - 0 751, P
