Asthma is a long term illness of the lungs that causes the airways to become inflamed and produce lots of mucus. Viral infections, cold air, allergens, exercise, and smoke make the airways “twitchy”; they close easily causing asthma attacks with coughing, wheezing and shortness of breath (see wh...at is asthma). Between attacks the airways are inflamed (see what is an allergy).

Asthma is chronic inflammation of the airways in the lungs.
In asthma, the airways in the lung narrow due to swelling of
the mucosa, increased mucus production, and spasm of the airways.
How to detect signs of Asthma
Using an inhaler is the most common and effective way of taking asthma medicines. If you’re NOT using your inhaler correctly, you might not be getting the full dose of medicine your doctor or asthma nurse prescribed because the medicine can’t reach your
lungs. Instead it might be hitting the ba...ck of your throat, orstaying on your tongue or in your mouth where it won’t help atall.

Asthma is a chronic lung disease affecting people of all ages. It is caused by inflammation and muscle tightening around the airways, which makes it harder to breathe.
Symptoms can include coughing, wheezing, shortness of breath and chest tightness. These symptoms can be mild or severe and can co...me and go over time.
Although asthma can be a serious condition, it can be managed with the right treatment. People with symptoms of asthma should speak to a health professional.

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.

We work with health care professionals and public health officials around the globe to reduce asthma prevalence, morbidity, and mortality.
Asthma is the most common chronic respiratory disease among school-going adolescents worldwide. However, the burden of severe asthma is highest in Sub-Saharan Africa. This study aimed to explore teachers’ perceptions of asthma care across six African countries. We conducted focus group discussions... (FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

As we approach World Asthma Day on the May 2, 2023, we reflect on the theme “ Asthma Care for All”. Prevalence of Asthma is increasing amongst children, adolescents and adults. Under-diagnosis, underutilization of inhaled corticosteroids, inaccessibility of treatment, and unaffordability of medi...cines are amongst the challenges that low-middle income countries are faced with. This commentary seeks to highlight the challenges, the resources available and to suggest recommendations that can be implemented to improve asthma care for all and reduce burden of asthma in Africa.

Asthma is one of the most common non-communicable diseases globally. This study aimed to assess asthma medicine use, management plan availability, and disease control in childhood, adolescence, and adulthood across different country settings.
Asthma is the most common chronic respiratory disease (CRD) worldwide and is estimated to affect 262 million causing significant mortality and morbidity, and has emerged as an important public health problem in many Latin American (LA) countries over the last 30 or so years. LA is a highly diverse r...egion in terms of geography, climate, wealth, and ethnicity including 20 different countries with 639 million inhabitants, where 40 million are estimated to have asthma. A common feature of LA countries is the high level of social inequalities3 (Figure 1). In LA, asthma prevalence in both children and adults is highly variable and, where high, is among the highest worldwide, particularly in coastal tropical cities.

Asthma is a serious global health problem affecting all age groups. Its prevalence is increasing in many countries, espacially among children. Although some countries have seen a decline in hospitalizations and deaths from asthma, asthma still imposes an unacceptable burden on health care systems, a...nd on society through loss of productivity in the workplace and, espacially for pediatric asthma, disruption to the family.

This study identifies barriers and provides recommendations to improve asthma care in children across sub-Saharan Africa, where qualitative data is lacking despite high rates.
As part of efforts to celebrate World Asthma Day (WAD), May 2, 2023, and reduce the burden of asthma in Nigeria, the Nigerian Thoracic Society (NTS) has advocated education of asthma patients and carers as an integral part of asthma care to achieve optimal control of symptoms and exacerbation.
Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

This study investigated occupational risk factors and exposure–response relationships for airway disease among health workers (HWs) exposed to cleaning agents in two tertiary hospitals in South Africa and Tanzania.
Previous studies have demonstrated an association between asthma or respiratory... symptoms and exposure to broad categories of cleaning-related exposures in healthcare settings. However, few studies have identified the specific cleaning agents responsible for asthma and other health outcomes. Products used for medical instrument cleaning and disinfection such as glutaraldehyde, orthophthalaldehyde (OPA) and quaternary ammonium compounds (QACs) have been implicated in the causation and exacerbation of work-related asthma (WRA) and upper airway outcomes such as rhinitis.
