Technical instructions for tuberculosis screening and treatment using cultures and directly observed therapy

"The medical screening for tuberculosis among persons overseas applying for U.S. immigration status and nonimmigrants who are required to have an overseas medical examination, hereafter referred to as applicants, is an essential component of the medical evaluation. Because tuberculosis is a challenging disease to diagnose, treat, and control, these instructions are designed to detect and treat tuberculosis disease among applicants and to reduce the risk of spread of tuberculosis among the U.S. population after immigration. The instructions in this document supersede all previous Technical Instructions, Updates to the Technical Instructions, memoranda and letters to panel physicians, and memoranda and letters to international refugee resettlement organizations. These instructions are to be followed for tuberculosis screening and treatment among all applicants." - prefacePreface -- Tuberculosis screening -- Tuberculosis screening results and travel clearance -- Tuberculosis treatment -- Waivers -- Tuberculosis treatment monitoring -- Contacts of tuberculosis cases -- Tuberculosis classifications and descriptions -- Documentation -- APPENDIX A.

Genetic characterisation of Norovirus strains in outpatient children from rural communities of Vhembe district / South Africa, 2014-2015

Background: Norovirus (NoV) is now the 24 most common causes of both outbreaks and sporadic non-bacterial gastroenteritis worldwide. However, data supporting the role of NoV in diarrheal disease are limited in the African continent. Objectives: This study investigates the distribution of NoV genotypes circulating in outpatient children from rural communities of Vhembe district / South Africa. Study design: Stool specimens were collected from children under five years of age with diarrhea, and controls without diarrhea, between July 2014 and April 2015. NoV positive samples, detected previously by Realtime PCR, were analysed using conventional RT-PCR targeting the partial capsid and polymerase genes. Nucleotide sequencing methods were performed to genotype the strains. Results: The sequence analyses demonstrated multiple NoV genotypes including GI.4 (13.8%), GI.5 (6.9%), GII.14 (6.9%), GII.4 (31%), GII.6 (3.4%), GII.P15 (3.4%), GII.P21 (3.4%) and GII.Pe (31%). The most prevalent NoV genotypes were GII.4 Sydney 2012 variants (n=7) among the capsid genotypes, GII.Pe (n=9) among the polymerase genotypes and GII.Pe/GII.4 Sydney 2012 (n=8) putative recombinants among the RdRp/Capsid genotypes. Two unassigned GII.4 variants were found. Conclusions: The findings highlighted NoV genetic diversity and revealed continuous pandemic spread and predominance of GII.Pe/GII.4 Sydney 2012, indicative of increased NoV activity. An unusual RdRp genotype GII.P15 and two unassigned GII.4 variants were also identified from rural settings of the Vhembe district/South Africa. NoV surveillance is warranted to help to inform investigations into NoV evolution and disease burden, and to support on-going vaccine development programmes

Clinical characteristics of children with 2009 pandemic influenza A (H1N1) admitted in a single institution

PurposeThis study aims to investigate the clinical characteristics of children diagnosed with the novel influenza A (H1N1) in the winter of 2009 at a single medical institution.MethodsOut of 545 confirmed cases of influenza A (H1N1) in children, using the real time RT-PCR method at Kosin University Gospel Hospital from September to December of 2009, 149 patients and their medical records were reviewed in terms of symptoms, laboratory findings, complications and transmission within a family.ResultsMedian age of subjects was 7 years (range: 2 months-18 years). New cases increased rapidly from September to reach a peak in November, then declined rapidly. Most frequently observed symptoms were fever (96.7%), cough (73.2%), rhinorrhea (36.9%) and sore throat (31.5%). Average body temperatures on the 1st, 2nd and 3rd hospital day were 38.75±0.65℃, 38.08±0.87℃ and 37.51±0.76℃, respectively. Complete blood counts and biochemical tests performed on the first admission day showed within the reference values in most cases. Of the 82 patients with simple chest radiography, 18 (22%) had pneumonic lesions; multi-focal bronchopneumonia in eleven, single or multi-segmental lobar pneumonia in five, and diffuse interstitial pneumonia in two patients. All of the 149 patients improved from their symptoms and discharged within 9 days of admission without any late complication.ConclusionChildren with 2009 pandemic influenza A (H1N1) at our single institution displayed nonspecific symptoms and laboratory findings, resembling those of common viral respiratory illnesses, and did not appear to develop more severe disease

No evidence of sustained spread was found, but 2 incidents of human-to-human transmission were suspected
