La fourniture de sang et de produits sanguins sûrs et efficaces pour la transfusion ou la fabrication d’autres produits sanguins fait intervenir un certain nombre de processus, allant de la sélection des donneurs de sang et de la collecte, au traitement et au dépistage des dons de sang ainsi qu...’à l’analyse des échantillons des malades, à la délivrance de sang compatible et à son administration au patient. Il existe un risque d’erreur à chaque étape de la « chaîne de transfusion », et une défaillance à une quelconque de ces étapes peut avoir des conséquences graves pour les receveurs du sang ou des produits sanguins. Si la transfusion sanguine peut sauver des vies, elle comporte aussi des risques, en particulier la transmission des infections par le sang.
Le dépistage des infections transmissibles par transfusion (ITT) en vue d’exclure les dons de sang présentant un risque de transmettre une infection du donneur aux receveurs est une étape critique du processus visant à garantir au mieux la sécurité des transfusions. Un dépistage efficace des agents transmissibles par le sang les plus courants et les plus dangereux peut réduire le risque de transmission à des niveaux très faibles.

This manual has been designed to be used in conjunction with two earlier WHO publications, "Basic tests for pharmaceutical substances" (1986) and "Basic tests for pharmaceutical dosage forms" (1991). Most of the pharmaceutical substances and dosage forms covered are included in the WHO Model List of... Essential Drugs. The present volume describes procedures for testing a further 23 pharmaceutical substances and 58 pharmaceutical dosage forms and also for testing 4 medicinal plant materials.

The objective of this course is to provide high-level information and contextual understanding of WHO Standard Operating Procedures (SOPs) for Emergencies.
We will explore a range of topics, ranging from the Emergency Response Framework (ERF), to planning, grants and finance, procurement, risk mana...gement, rosters and deployment, and ethics.
Each module within this course is standalone. Therefore, you can take the modules in any order – with the exception of the Course Review. The Course Review is a question-based revision module that recaps the content covered in modules 1 to 10.
The target audience for this course is personnel who will be assigned by WHO to go on deployment in response to health emergencies.
The course is available in English and French

Pollution (dirty air) is a big trigger for asthma as it makes it difficult to breathe and affects the health of humans, animals, and plants. Avoiding pollution helps prevent asthma symptoms!
Asthma is a long term illness of the lungs that causes the tubes that carry air into and out of the lungs (airways) to become swollen (inflamed) and produce lots of thick mucus.
In a person with asthma, the lung swelling (inflammation) makes the airways “twitchy”; this means they close easily... with certain things like viral infections, cold air, allergens, exercise, and smoke.

When someone is having an asthma attack, their airways go into spasm which causes tightness of the chest; the linings of the airways become inflamed and phlegm is produced further obstructing the airways and leading to severe difficulty in breathing (Fig. 1). Asthma does lead to fatalities and shoul...d always be taken seriously.

Secondhand smoke can infiltrate into other units through hallways and stairwells. Don’t be shy when it comes to your health. Talk to your building manager about making your apartment smokefree.
Secondhand smoke and the harmful chemicals in it are known causes of Sudden Infant Death Syndrome RESPIRATORY INFECTIONS, ear infections.and asthma attacks in infants and children. They are also known causes of HEART DISEASE,stroke, and lung cancer in adult nonsmokers.
Asthma is a chronic lung condition that affects your airways or bronchial tubes. It causes your airways to narrow, swell and produce extra mucus, which in turn makes it more difficult to breathe. The narrowing of the airways causes you to feel short of breath, wheezy or trigger fits of coughing.

the mucosa, increased mucus production, and spasm of the airways.
This American Thoracic Society Statement was prepared by a Committee of the Scientific Assembly on Environmental and Occupational Health at the request of the American Lung Association Occupational Health Expert Advisory Group to emphasize the continuing importance of silicosis as a major lung disea...se worldwide and the need for increasing efforts in prevention. Emphasis is placed on public health issues of silicosis rather than on important current research in pathologic mechanisms.
