The study was carried out in the National Institute of Ophthalmology from August 2001 to August 2002 on 102 children having unilateral or bilateral refractive errors and an isometrope of at least one dioptre. The patients having various amplyopia due to isometrope were usually examined lately (at the age of 6 to 10 years). The main cause of amblyopia were hypermetrope and astigmatism. All the patients were best corrected and their amblyopia was treated by eye occlusion and stimulating training. The treatment was continued by wearing full corrected glasses, occlusion of the better eye and penalization. One year after treatment, 100% of patients have improved acuity of vision. 80.3% obtained good results. The long term result in the patients having penalization with glasses was better.

As authorities braced for the arrival of the Omicron variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), infrastructure investments and government directives prompted action in central Viet Nam to establish capacity for genomic surveillance sequencing. From 17 November 2021 to 7 January 2022, the Pasteur Institute in Nha Trang sequenced 162 specimens from 98 150 confirmed SARS-CoV-2 cases in the region collected from 8 November to 31 December 2021. Of these, all 127 domestic cases were identified as the B.1.617.2 (Delta) variant, whereas 92% (32/35) of imported cases were identified as the B.1.1.529 (Omicron) variant, all among international flight passengers. Patients were successfully isolated, enabling health-care workers to prepare for additional cases. Most (78%) of the 32 Omicron cases were fully vaccinated, suggesting continued importance of public health and social measures to control the spread of new variants.
