COVID-19 is a disease caused by a new strain of coronavirus, a new coronavirus associated with the severe acute respiratory syndrome (SARS) viruses family and some coronaviruses associated with common cold.
There is still no evidence that persons living with HIV have a higher risk of contracting CO...VID-19 or if they will experience further complications of the disease, in case of contracting it. Nevertheless, it is very important that persons with HIV take all necessary precautions to prevent the spread.

Onchocerciasis causes skin and eye disease, visual impairment and neurological problems. It is mostly found in Africa, but also in Latin America and Yemen. The common name, ‘river blindness,’ gives a good indication where the disease can be found: the vector of the parasite, a small black fly of... the Simulium species, breeds in rivers where there is turbulence in the water, such as rapids, or where the flow is disturbed by overhanging vegetation.

Cardiovascular disease (CVD) is often thought to be a problem of wealthy, industrialized nations. The term “cardiovascular disease” is used throughout the report to refer to cardiac disease, vascular diseases of the brain and kidney, and peripheral vascular disease. The report’s main focus is ...on the major contributors to global CVD mortality, coronary heart disease and stroke, and on the major modifiable risk factors for cardiovascular diseases. In fact, as the leading cause of death worldwide, CVD now has a major impact not only on developed nations but also on low and middle income countries, where it accounts for nearly 30 percent of all deaths. The terms “developed” and “high income countries” are used interchangeably throughout the report to refer to countries classified by the World Bank as high income economies. The terms “developing” and “low and middle income countries” are used interchangeably throughout the report to refer to countries classified by the World Bank as low, lower middle, and upper middle income economies. The increased prevalence of risk factors for CVD and related chronic diseases in developing countries, including tobacco use, unhealthy dietary changes, reduced physical activity, increasing blood lipids, and hypertension, reflects significant global changes in behavior and lifestyle. The term “chronic diseases” is used throughout the report to refer to CVD and the following related chronic diseases that share many common risk factors: diabetes, cancer, and chronic respiratory disease. These changes now threaten once-low-risk regions, a shift that is accelerated by industrialization, urbanization, and globalization. The potentially devastating effects of these trends are magnified by a deleterious economic impact on nations and households, where poverty can be both a contributing cause and a consequence of chronic diseases. The accelerating rates of unrecognized and inadequately addressed CVD and related chronic diseases in both men and women in low and middle income countries are cause for immediate action.

Chronic noncommunicable diseases (NCDs) are the number one cause of death and disability in the world.
The term NCDs refers to a group of conditions that are not mainly caused by an acute infection, result in long-term health consequences and often create a need for long-term treatment and care. ...These conditions include cancers, cardiovascular disease, diabetes and chronic lung illnesses.
Many NCDs can be prevented by reducing common risk factors such as tobacco use, harmful alcohol use, physical inactivity and eating unhealthy diets. Many other important conditions are also considered NCDs, including injuries and mental health disorders.

In the WHO South-East Asia Region, epidemiological knowledge of mental health conditions remains
a relative unknown, given the sparsity of data and information on (a) the total burden associated
with each disorder; (b) the degree of met and unmet needs for treatment and interventions; and
(c) the... patterns and costs of treatment. This is a common situation in other regions of the world,
where the global descriptive epidemiology of the Global Burden of Disease (GBD) study is mainly
used in association with the WHO Global Health Estimates (GHE) to quantify, at the very least, the
total burden associated with mental health conditions.

Cervical cancer is a disease of the female reproductive tract caused primarily by oncogenic types of human papillomavirus
(HPV). In 2020, it was the fourth most common cancer among women worldwide, with an estimated 604 000 new cases and 342 000 deaths
Sepsis contributes significantly to preventable mortality and is the final common pathway to death for severe infectious diseases; it can also arise as a complication of injuries and non-communicable diseases.
Leishmaniasis is a vector-borne disease with a broad global distribution and an increasing number of recorded cases worldwide. However, it is still one of the world's most neglected diseases. Over the last decades, the disease has been found to expand geographically with a global increase of cases o...f visceral and cutaneous leishmaniasis increasing the public health problems associated with the disease epidemics. The reported range expansion of the diseases has been associated with range expansions of vector populations in response to climate change. Leishmaniasis is caused by protozoan parasites of the genus Leishmania. The transmission can either be zoonotic and/or anthroponotic through the bite of an infected female phlebotomine sandfly. In Eurasia and Africa, all vector-competent sandfly species belong to the genus Phlebotomus. Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis. In the ‘old world’, it is caused by five currently recognized Leishmania species: L. major, L. tropica and L. aethiopica (being main causative parasites) as well as L. infantum and L. donovani. Visceral leishmaniasis (VL), another common and more severe form of leishmaniasis, is only associated with the Leishmania species L. infantum and L. donovani. The specific Leishmania species cause different clinical symptoms in humans.

BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

Human Papilloma Virus (HPV) is the most common sexually transmitted infection, and two types of HPV (16 and 18) cause nearly 50% of high-grade cervical pre-cancers. HIV and cervical cancer are inextricably linked. Women living with HIV are six times more likely to develop cervical cancer, which is o...ne of the AIDS-defining illnesses and the most common cancer among women living with HIV globally. Cervical cancer is a preventable, curable disease and can be eliminated as a public health problem with primary and secondary prevention, treatment, and care of cervical cancer, in combination with addressing social, health and other inequalities and integrated approaches.

Cutaneous leishmaniasis (CL) is a parasitic disease caused by infection with a vector-borne protozoan parasite of the genus Leishmania spp. The parasite is transmitted by the bite of an infected phlebotomine sand fly. Infection results in skin lesions which take a long time to heal and may leave per...manent, disfiguring scars (de Vries et al. 2015). CL is classified as a neglected tropical disease (NTD), and in common with several other NTDs, is associated with psychosocial effects including stigma, social exclusion, and declining mental health (Bailey et al. 2019; Bennis et al. 2018; Wenning et al. 2022). Emerging evidence suggests that people with CL are at a higher risk of experiencing anxiety, depression, decreased body satisfaction, loss of social status, and lower quality of life (Bennis et al. 2018; Yanik et al. 2004). The global mean age-standardised disability-adjusted life years (DALYs) lost by CL was 0.58 per 100,000 people (Karimkhani et al. 2016). Notably, this statistic only considers the physical effects of the lesions and does not account for the potentially considerable psychological and social effects of CL (Bailey et al. 2017; Bailey et al. 2019; Wenning et al. 2022).

Leishmaniasis is a vector-borne tropical/subtropical disease caused by an intracellular parasite transmitted to humans by sand fly bite. It is endemic in Asia, Africa, the Americas, and the Mediterranean region. Worldwide reports include 1.5–2 million new cases each year, more than 300 million at ...risk of acquiring the disease, and 70,000 deaths per year. Clinical features depend on the Leishmania species and immune response of the host, varying from localized cutaneous disease to visceral form with potentially fatal outcome; however, the common presentation is either cutaneous, mucocutaneous, or visceral leishmaniasis. Many therapeutic agents are being used in Leishmania treatment, but the only effective treatment is achieved with current pentavalent antimonials. WHO considers Leishmaniasis as one of the “Neglected Tropical Diseases” that continues to be prevalent despite international, national, and local efforts towards its control and elimination over the last decade. This chapter reviews the global perspective of Leishmaniasis with increasing recognition of emerging “Atypical forms” and new surge of disease across the world mainly due to increasing conflicts in endemic areas leading to forced migration among other causes. All these challenges related to environment, disease, and vector pose major implications on WHO’s leishmaniasis control and elimination plan.

Vaccines are designed to give you immunity without the dangers of getting the disease. It’s common to experience some mild to moderate side effects when receiving vaccinations. This is because your immune system instructs your body to increase blood flow so more immune cells can circulate, and it ...raises your body temperature to kill the virus. Vaccines help protect us against disease and feeling mild or moderate side effects after receiving one is a sign that the vaccine and our immune system is working.

Maldives has made significant strides in the area of infectious disease prevention and control. This is exemplified by elimination of malaria from Maldives in 2015 and successes in TB control. In addition, Maldives is a front runner in infectious disease prevention through successful water, sanitati...on, hygiene and vaccination campaigns and coverage. However, given the limited evidence that exists with respect to the occurrence of resistant organisms in the nation, it is hard to estimate the exact antimicrobial resistance (AMR) scenario. Also, it becomes difficult to compare the current situation with other countries in the region. Moreover, limited evidence exists on the trends of use of antimicrobial agents (AMA) in Maldives. Although, recent prescription audits have indicated overuse of antibiotics, especially for common conditions such as flu, cough and fever.

Leptospirosis is a perplexing conundrum for many. In the existing literature, the pathophysiological mechanisms pertaining to leptospirosis is still not understood in full. Considered as a neglected tropical zoonotic disease, leptospirosis is culminating as a serious problem worldwide, seemingly exi...sting as co-infections with various other unrelated diseases, including dengue and malaria. Misdiagnosis is also common as non-specific symptoms are documented extensively in the literature. This can easily lead to death, as the severe form of leptospirosis (Weil’s disease) manifests as a complex of systemic complications, especially renal failure. The virulence of Leptospira sp. is usually attributed to the outer membrane proteins, including LipL32. With an armament of virulence factors at their disposal, their ability to easily adhere, invade and replicate within cells calls for a swift refinement in research progress to establish their exact pathophysiological framework. As an effort to reconstitute the current knowledge on leptospirosis, the basis of leptospiral infection, including its risk factors, classification, morphology, transmission, pathogenesis, co-infections and clinical manifestations are highlighted in this review. The various diagnostic techniques are also outlined with emphasis on their respective pros and cons.

Washing hands is the best way to prevent the spread of germs and diseases. Dirty hands can carry pathogenic germs that can sicken a person or spread diseases to others. Microorganisms such as bacteria, viruses, parasites, fungi and various chemicals can enter our bodies directly when we touch our fa...ce, eyes, nose or mouth or may enter indirectly, when our dirty hands stain surfaces touched by others or where food is prepared. The habit of washing hands with soap and water constitutes the first line of defense against the spread of many diseases, from the common cold or diarrhea to more serious illnesses such as meningitis, influenza or hepatitis as well as many other diseases. This 2-D animation describes the importance of hand washing.
