Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

UNHCR’s Public Health Strategy 2021-2025 is based on the lessons learnt, and builds on the achievements, of the Global Strategy for Public Health 2014-2018.
Progress was made on policies favouring inclusion and integration into national systems3 with 92% of 48 operations surveyed reporting refuge...es having access to national primary health care facilities under the same conditions as nationals and 96% reporting refugees having access to all relevant vaccines under the same conditions as nationals. While many refugee hosting countries have policies that allow refugees to access national health services, many face partial access, prohibitive out-of-pocket expenditures and other barriers including distance to facilities, language and provider acceptance. Furthermore, more work is needed on strengthening these systems to be able to meet the needs of both host communities and refugees.

The purpose of the report is to present some first recommendation for the development of Myanmar ecological quality criteria using the system of the EU Water Framework Directive (EU WFD) as baseline, with main focus on the characterization and classification processes. As background for the recommen...dations we first give an overview of the main water use categories in Myanmar. We then provide preliminary suggestions for typology criteria and indices for assessing ecological status in lakes and rivers in Myanmar. The typology factors and physico-chemical parameters are based on common used factors in the EU countries. The biological elements include phytoplankton and aquatic macrophytes for lakes, and benthic invertebrates for rivers.

The results of in-country database and reports analysis
The marathon to eradicate polio is on its final lap: the world is more than 99% of the way to success. After millennia of living with poliovirus and suffering the paralysis it causes, today nearly all the world’s people live in polio-free countries; two of the three strains of wild poliovirus (WPV...) have been eradicated. Some 20 million people are walking who would have been paralysed had it not been for the efforts of national governments and health workers. If eradicating polio has been a marathon, the finishing line is in sight.
