Myocardial infarctions are generally clinically classified into ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI), based on changes in ECG. When blood flow to a part of the heart stops or the heart is injured and fails to receive enough oxygen required for its adequate functioning the conditi...on is termed as STEMI or the ‘heart-attack’ in laymen language. Patients with elevated cardiac troponin levels but negative CK-MB who were formerly diagnosed with unstable angina or minor myocardial injury are now reclassified as non-ST-segment elevation Myocardial Infarction (non-STEMI) even in the absence of diagnostic changes.

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.

Safe sanitation is essential for health, from preventing infections to improving and maintaining mental and social
well-being. Lack of adequate sanitation contributes to diarrhoeal diseases, parasitic infections, and undernutrition, as
well as pos...ing significant risks and causing anxiety, especially for women and girls. Achieving universal access to safe
sanitation, which protects health, privacy, and dignity, is a global development goal and a recognized basic human right.

On the road to ending TB
Highlights from the 30 highest TB burden countries
The Strategic Framework for Emergency Preparedness is a unifying framework which identifies the principles and elements of effective country health emergency preparedness. It adopts the major lessons of previous initiatives and lays out the planning... and implementation process by which countries can determine their priorities and develop or strengthen their operational capacities. The framework capitalizes on the strengths of current initiatives and pushes for more integrated action at a time when there is both increased political will and increased funding available to support preparedness efforts.

The Greater Horn of Africa is experiencing one of the worst food insecurity situations in decades. It is estimated
that more than 37 million people are in Integrated Food Security Phase Classification (IPC)1 phase 3 or above and approximately 7 million children under the age of five are acutely mal...nourished in the region. While finding food and safe water is the absolute priority, the health response is essential to avert preventable disease and death.

WHO published the first COVID-19 Strategic Response and Preparedness Plan (SPRP) on 3 February, 2020. This report highlights the main points of progress that were made up to 30 June 2020 under the three objectives outlined in the SPRP: scaling up international coordination and support; scaling up co...untry preparedness and response by pillar; and accelerating research and innovation. The report also discusses some of the key challenges faced so far, and provides an update on the resource requirements for the next phase of WHO’s response as part of an unprecedented whole-of-UN approach to the pandemic.

Noncommunicable diseases (NCDs) are the principal cause of morbidity, disability and premature mortality in Azerbaijan. The most effective way to reduce the NCD burden is to prevent NCD development, by addressing thebehavioural risk factors underlying NCDs at the population and individual leve...ls: smoking, alcohol use, excessive salt intake, low physical activity, overweight and obesity, and unhealthy diets. In Azerbaijan, a national survey of the prevalence of major NCD risk factors, aligned with the WHO-endorsed STEPwise approach to surveillance (STEPS) methodology, was conducted in 2017.
