Background: The increasing use of computers and electronic devices is rapidly increasing the related health issues of computer vision syndrome. Studies have identified longer use of computers, ergonomic practices as lighting condition of room, incorrect distance between eye and computer, refresh rate, use of spectacles were associated with computer vision syndrome (CVS) symptoms as back pain, tension, headache and others. The objective of this study was to find out the prevalence of CVS among computer engineering students of Pokhara University affiliated colleges of Kathmandu Valley and identify the associated factors and preventive measures being practiced by the students.Methods: A cross-sectional descriptive study was carried out using self-administered questionnaire among 234 undergraduate computer engineering students of Kathmandu Valley. Chi-square test was used to identify the association with computer vision syndrome and its determinants.Results: The prevalence of computer vision syndrome among the computer engineering students was found to be 76.50%. Only 39.3% were found to be using computer in upright with straight back posture and 73.5% were using computer at distance less than or equal to 50 cm. The 81.2% of participants were not following the 20/20/20 rule. During age, use of vision aid lens and use of protective eye glasses and artificial eye drops were found associated with CVS.Conclusions:The study revealed that the prevalence of computer vision syndrome was significantly high. Individuals using vision aid lens were found to be at risk of developing CVS and use of protective eye glass and artificial tears were found protective.

Dear Editor, Rising and remerging pathogens are worldwide difficulties for open health.1 Coronaviruses are wrapped RNA infections that are dispersed extensively among people, different warm-blooded creatures, and flying creatures and that cause respiratory, enteric, hepatic, and neurologic diseases.2, 3 Six coronavirus species are known to cause human illness like 229E, OC43, NL63, and HKU1, SARS – CoV and MERS – CoV.4 Given the high predominance and wide circulation of coronaviruses, the huge hereditary decent variety and successive recombination of their genomes, and expanding human–creature interface exercises, novel coronaviruses are probably going to develop intermittently in people attributable to visit cross-species contaminations and incidental overflow events.5, 6 On January 30, World Health Organization (WHO) pronounced the ebb and flow flare-up that began in Wuhan, China as a Public Health Emergency of International Concern, while prescribing against movement or exchange interruptions to and from China.7 The progressing pandemic of coronavirus ailment 2019 (COVID-19) is brought about by extreme intense respiratory disorder coronavirus 2 (SARS-CoV-2).8 As of 12 April 2020, in excess of 1,777,515 instances of COVID-19 have been accounted for in more than 200 nations and regions, bringing about in excess of 108,862 passings.

Avian flu also known as bird flu is caused by deadly virus H5N1 which initially was found in birds and wild animals, however, later it was found in human beings causing severe respiratory related problems. This review article was performed to understand the epidemiology of outbreaks of H5N1 in different districts of Nepal. First outbreak of strain H5N1 was reported in 2009. Consequently, highest number of outbreaks i.e. 201 was noted in the year 2013. Till date only one human case was identified by NPHL which was later confirmed by genetic laboratory in Japan in collaborating with WHO.
