The study was carried out on 400 pregnant women and 400 military candidates in Ha Noi in 2003 to evaluate sexually transmitted infections (STIs). The result showed that: HIV infection rate in pregnant women was high (0.75%) and in military candidate was 0.25%. Syphilis was detected at the same rate in two groups: 0.25%. Using PCR technique, the researcher detected gonorrhea and C.trachomatis rates military candidate group were very high (2.0% and 9.0%, respectively), and the rates in pregnant women group was low (0.0% and 1.5%, respectively)

A descritive study on 2606 people (≥15 year old) who suffered from cough and plegm production that lasted over 3 weeks with the symptoms of suspicious tuberculosis at 20 villages in districts of Văn Lâm, Mĩ Hào, Khoái Châu, Ân Thi, Tiên Lữ, Hưng Yên province from Jan 2000 to Dec 2004. The new incidence of tuberculosis AFB (+) in year 2000: 88.70 AFB (+)/100.000 people, it wasn’t steady and 1.29 time higher than the incidence people in the whole country. Males had higher risk by 1.81 times than females. The illiterates had higher risk by 2.11 times than other subjects. The people who contact with transmitted sources had higher risk by 5.47 times than people who had not this history. There is no relation between occupations, age with TB. This proportion is higher than previous year (1989-1997) from 27.62% to 50.34%; higher than in year 2001: 58.62%; year 2002: 38.59%, year 2003:17.48%, year 2004: 35.00%.
Tuberculosis ; Epidemiology

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.
