“…Symptoms related to orthopedics, psychiatry and ophthalmology have been documented in previous studies [12,13] . The ocular symptoms experience by VDTs users typically include eyestrain, eye fatigue, burning sensations, irritation, redness, blurred vision and dry eyes [7,14,15] .…”

To find out ocular symptoms in Visual Display Terminals (VDTs) users, among undergraduate students who adopted new education system in this COVID-19 era. Methods: A cross-sectional, observational survey carried out in the month of September 2020, which included undergraduate students from Ahmedabad, who were using Visual Display Terminals (VDTs) for educational activities for more than 6 to 8 months. A total of fourteen validated questionnaires were selected, webpage survey form was created and the link was sent via various social media platform. Responses were assessed in the scale of 0 to 4 (0= never, 1=infrequently, 2=sometimes, 3= often, 4=always). The percentage of symptoms was calculated in terms of subjects, also in the scale of 0 to 4. Results: A total of 103 undergraduate students responded with mean age of 19±1.5 years. Highest number (40: 4-6 hours, 36: 7-9 hours) of students had a screen time of 4 to 9 hours per day. The burning sensation (69.8%), redness (51.4%), itching (47.6%) were the most common symptoms, followed by irritation (34.6%), and scratchiness (25.5%) related to dry eyes. However, majority of the patients had those symptoms on infrequent duration. A loss of the concentration (73.8%), tired eyes (69.6%), discomfort (61.2%), headache (60.7%), reduced reading speed (56.3%), fluctuation in vision (44.7%), blurring (43.7%), were the most common symptoms related to the near work. Majority of participants felt these complain for the duration of infrequent to often basis. The double vision (25.2%) and floating of objects (11.7%) were the least common symptoms related to near work. Conclusion:The VDTs related symptoms are increasing in the students in this COVID-19 era. Increasing awareness, proper counselling regarding algorithm of VDTs, taking regular breaks, avoiding unnecessary web searching and social media can help to relieve or minizine symptoms related to VDTs work in this COVID-19 era.

“…Furthermore, most of the dengue cases in the last 10 years were reported from the northern states of Mexico, where DENV-1 and DENV-2 are the predominant serotypes. The DENV-1 isolate from this study clustered with other Mexican and Central American strains of DENV-1 belonging to genotype V. DENV-1 genotype V has been circulating in Mexico since the late 1970s and has experienced several lineage replacements since its introduction, causing a high degree of genetic variability [ 9 ]. Moreover, DENV-1 genotype V is widely distributed in the Americas, and its clades are associated with distinct regions (South America, Caribbean, and Central America) [ 10 ].…”

Characterization of a Dengue Virus Serotype 1 Isolated from a Patient in Ciudad Juarez, Mexico

Dengue (DEN) is the most important human arboviral disease worldwide. Sporadic outbreaks of DEN have been reported since 1980 in urban communities located along the border in southeast Texas and northern Mexico. Other than the Rio Grande Valley region of TX, autochthonous transmission of DENV has not been reported from any other US border communities. As part of a surveillance program for arthropod-borne viruses in Ciudad Juarez, Mexico, during November 2015, a blood sample was obtained from a female patient who experienced an undifferentiated fever and arthralgia. The plasma of the sample was tested for virus in Vero-76 and C6/36 cells. DENV serotype 1 (DENV-1) was isolated in the C6/36 cells, and nucleotide sequencing of the envelope gene and full genome grouped the DENV-1 isolate in the Central America clade. The patient had not traveled outside of Ciudad Juarez, Mexico, thus suggesting DENV-1 infection was acquired in this community.

“…A clear example of In-DRE's contribution was the characterization of a highly pathogenic avian A influenza strain (H7N3) in poultry farm workers from Jalisco. 10 The transmission of the chikungunya 11 , Zika 12 , and dengue 13 viruses in our country was also studied, the circulation of non-polio D68 enterovirus was identified in respiratory conditions and the diagnosis of influenza in children was ruled out at the Institute. 14 Detection of the Aedes mosquito in Mexico City 15 triggered focused monitoring and surveillance activities.…”

This document describes the changes at the Institute of Epidemiological Diagnosis and Reference (InDRE) from 2012 to 2019, the administrative and equipment modifications, the new headquarters and the National System of Epidemiological Surveillance legal modifications. The process of relocation is mentioned, especially the careful transfer of the biological material protected by the Institute, and the new way of studying epidemic outbreaks, endemic diseases and the negative network is analyzed. At the international level, the promotion of links with global networks of the Pan American Health Organization, the World Health Organization (WHO) and other international organizations is described. The assignation to InDRE of four WHO collaborating centres is also mentioned. The Global Health Security Initiative Laboratory Network acknowledged InDRE's leadership, which co-chaired the working group during the study period.
