Le syndrome respiratoire aigu provoqué par le coronavirus-2 (SARS-CoV-2), initialement décrit en Chine, est responsable
de la pandémie que nous connaissons actuellement sous le nom de coronavirus disease 2019 ou COVID-19. L'épidémie de
coronavirus a été déclarée « urgence de santé publi...que mondiale » par l'Organisation mondiale de la santé (OMS) le 30 janvier 2020 . L'Afrique a été atteinte plus tard que les autres continents, mais à la date du 3 mai, tous les pays africains
avaient notifié au moins un cas. À la date du 09 juin 2020, l'Afrique comptait près de 200 000 cas confirmés, plus de
5000 décès, avec 25 pays ayant plus de 1000 cas actifs. Les patients atteints par ce virus peuvent développer des symptômes allant jusqu'à l'insuffisance respiratoire aiguë sévère

Long-term exposure of humans to air pollution enhances the risk of cardiovascular and respiratory diseases. A novel Global Exposure Mortality Model (GEMM) has been derived from many cohort studies, providing much-improved coverage of the exposure to fine particulate matter (PM2.5). We applied the GE...MM to assess excess mortality attributable to ambient air pollution on a global scale and compare to other risk factors.
Methods and results
We used a data-informed atmospheric model to calculate worldwide exposure to PM2.5 and ozone pollution, which was combined with the GEMM to estimate disease-specific excess mortality and loss of life expectancy (LLE) in 2015. Using this model, we investigated the effects of different pollution sources, distinguishing between natural (wildfires, aeolian dust) and anthropogenic emissions, including fossil fuel use. Global excess mortality from all ambient air pollution is estimated at 8.8 (7.11–10.41) million/year, with an LLE of 2.9 (2.3–3.5) years, being a factor of two higher than earlier estimates, and exceeding that of tobacco smoking. The global mean mortality rate of about 120 per 100 000 people/year is much exceeded in East Asia (196 per 100 000/year) and Europe (133 per 100 000/year). Without fossil fuel emissions, the global mean life expectancy would increase by 1.1 (0.9–1.2) years and 1.7 (1.4–2.0) years by removing all potentially controllable anthropogenic emissions. Because aeolian dust and wildfire emission control is impracticable, significant LLE is unavoidable.
Conclusion
Ambient air pollution is one of the main global health risks, causing significant excess mortality and LLE, especially through cardiovascular diseases. It causes an LLE that rivals that of tobacco smoking. The global mean LLE from air pollution strongly exceeds that by violence (all forms together), i.e. by an order of magnitude (LLE being 2.9 and 0.3 years, respectively).

Long Acting Muscarinic Antagonists (LAMA) such as tiotropium and glycopyrronium are used in the management of COPD1. They have been shown to improve lung function, quality of life and exercise tolerance. They have also been associated with reduced COPD-related exacerbations, associated hospitalisati...ons and duration of hospital stay. Both the South African Thoracic Society (SATS) and Global Initiative for Chronic Obstructive Lung Disease (GOLD), guidelines recommend the use of long acting anticholinergic drugs (or long acting beta agonists) in moderate to very severe disease as defined by lung function (FEV1). The most up to date guideline, utilizing the GRADE methodology (European Respiratory Society guidelines of 2017), confirms their superiority over long acting β agonists (LABA) as monotherapy for COPD in that LAMA's have demonstrated greater efficacy in terms of exacerbation reduction, with similar safety profile.2 These recommnedations are supported by published peer-reviewed
evidence including individual papers and Cochrane reviews.

WHO has published the guidance “Clinical management of severe acute respiratory infection (SARI) when COVID-19 disease is suspected” This document is intended for clinicians taking care of hospitalized adult and paediatric patients with severe acute respiratory infection (SARI) whe...n COVID-19 infection is suspected. Optimized supportive care should be provided to ensure the best possible chance for survival of COVID-19 patients as described in the WHO guidance:
1. Management of severe COVID-19 requires oxygen therapy and monitoring. Supplemental oxygen therapy should be given immediately to patients with SARI and respiratory distress, hypoxaemia or shock.
2. Management of critical COVID-19 (acute respiratory distress syndrome (ARDS)) requires advanced oxygen/ventilatory support.

Spirometry is required as part of the comprehensive evaluation of both adult and paediatric individuals with suspected or confirmed respiratory diseases and occupational assessments. It is used in the categorisation of impairment, grading of severity, assessment of potential progression and response... to interventions. Guidelines for spirometry in South Africa are required to improve the quality, standardisation and usefulness in local respiratory practice. The broad principles of spirometry have remained largely unchanged from previous versions of the South African Spirometry Guidelines; however, minor adjustments have been incorporated from more comprehensive international guidelines, including adoption of the Global Lung Function Initiative 2012 (GLI 2012) spirometry reference equations for the South African population.
All equipment should have proof of validation regarding resolution and consistency of the system. Daily calibration must be performed, and equipment quality control processes adhered to. It is important to have standard operating procedures to ensure consistency and quality and, additionally, strict infection control as highlighted during the COVID-19 pandemic.
Adequate spirometry relies on a competent, trained operator, accurate equipment, standardised operating procedures, quality control and patient co-operation. All manoeuvres must be performed strictly according to guidelines, and strict quality assurance methods should be in place, including acceptability criteria (for any given effort) and repeatability (between efforts).

Current evidence indicates that the COVID-19 virus is transmitted through respiratory droplets or contact. Contact transmission occurs when contaminated hands touch the mucosa of the mouth, nose, or eyes; the virus can also be transferred from one surface to another by contaminated hands, which fac...ilitates indirect contact transmission. Consequently, hand hygiene is extremely important to prevent the spread of the COVID-19 virus. It also interrupts transmission of other viruses and bacteria causing common colds, flu and pneumonia, thus reducing the general burden of disease.
