Ebola, a member of the Filoviridae virus family, is notorious for causing a severe and often deadly viral hemorrhagic fever. It has been documented in outbreaks among primates, including gorillas and chimpanzees, as well as humans. Symptoms include intense fever, rash, and severe bleeding. The fatality rate in humans is alarmingly high, ranging from 50 to 90 percent.

The Ebola virus derives its name from the Ebola River located in the northern Congo basin of central Africa, where it was first identified in 1976. That year, outbreaks in Zaire (now Congo [Kinshasa]) and Sudan led to hundreds of fatalities, as did a subsequent outbreak in Zaire in 1995. Ebola is closely associated with the Marburg virus, discovered in 1967, and together they are the sole members of the Filoviridae family known to cause widespread human disease. A related strain, Ebola Reston, triggered an outbreak among laboratory monkeys in Reston, Virginia, but it does not appear to be lethal to humans.

Poliomyelitis, commonly referred to as polio or infantile paralysis, is a severe viral infection affecting the nervous system. Initial symptoms often include fever, headache, nausea, fatigue, and muscle pain or spasms. In some cases, this progresses to permanent muscle paralysis in limbs, the throat, or chest. While over half of polio cases occur in children under five, fewer than 1 percent of those infected experience paralysis.

Between 5 and 10 percent of individuals infected with the poliovirus exhibit only mild symptoms, while over 90 percent show no signs of illness. There is no cure for polio, and during the mid-20th century, it affected hundreds of thousands of children annually. Thanks to widespread vaccination efforts since the 1960s, polio has been largely eradicated globally, remaining endemic only in parts of Africa and South Asia. Each year, around 1,000–2,000 children, primarily in India, suffer paralysis due to the disease.

Commonly known as lupus, this autoimmune disorder leads to persistent inflammation in various body parts. It is categorized into three primary types: discoid, systemic, and drug-induced.

Discoid lupus is limited to the skin and typically spares internal organs. It is characterized by distinct red patches covered with grayish-brown scales, often appearing on the face, neck, and scalp. Approximately 10 percent of individuals with discoid lupus may develop the more severe systemic form of the condition.

Systemic lupus erythematosus (SLE) is the most prevalent form of lupus, potentially impacting almost any organ or body structure, including the skin, kidneys, joints, heart, gastrointestinal tract, brain, and serous membranes. While SLE can affect multiple areas, most individuals experience symptoms in only a few organs. The skin rash, if present, resembles that of discoid lupus. Symptoms vary widely between individuals, and the disease alternates between active phases and periods of remission.

Influenza, commonly referred to as the flu or grippe, is a highly contagious viral infection affecting the upper or lower respiratory tract. Symptoms include fever, chills, muscle pain, fatigue, and discomfort in the head and abdomen.

The flu is caused by various strains of orthomyxoviruses, classified into types A, B, and C. While these types produce similar symptoms, they are antigenically distinct, meaning immunity to one does not protect against the others. Type A viruses are responsible for major epidemics, while type B causes smaller outbreaks. Type C viruses rarely cause significant illness in humans. Influenza viruses continuously evolve through antigenic drift, adapting to human immunity. Occasionally, they undergo significant changes through antigenic shift, creating new subtypes to which most people lack immunity.

Creutzfeldt-Jakob disease is a rare and fatal degenerative disorder affecting the central nervous system. It occurs globally at a rate of one case per million people, though certain groups, such as Libyan Jews, exhibit higher incidence rates. Typically affecting individuals aged 40 to 70, it can also occur in younger adults. Both genders are equally susceptible. Initial symptoms often include subtle psychiatric or behavioral changes, followed by rapid dementia, visual disturbances, and involuntary movements. There is no cure, and the disease is usually fatal within a year of symptom onset.

First identified in the 1920s by German neurologists Hans Gerhard Creutzfeldt and Alfons Maria Jakob, this disease shares similarities with other neurodegenerative conditions like kuru in humans and scrapie in sheep and goats. All three are classified as transmissible spongiform encephalopathies, characterized by a spongy appearance in brain tissue due to neuronal destruction.

Diabetes is a metabolic disorder affecting carbohydrate processing, marked by the body's inability to produce or effectively use insulin, leading to improper regulation of blood sugar (glucose) levels.

The disease manifests in two primary forms. Type I diabetes, previously known as insulin-dependent diabetes mellitus (IDDM) or juvenile-onset diabetes, typically develops in childhood. It is an autoimmune condition where the immune system attacks and destroys insulin-producing beta cells. As a result, individuals require daily insulin injections to manage their condition.

Type II diabetes, formerly termed non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes, usually emerges after age 40 and becomes more prevalent with aging. It results from either insufficient insulin production or the body's reduced sensitivity to insulin. Genetic factors and obesity, particularly upper-body obesity, are significant contributors. Management includes dietary adjustments, exercise, and, if needed, insulin injections or oral medications.

AIDS, short for acquired immunodeficiency syndrome, is a contagious disease of the immune system caused by the human immunodeficiency virus (HIV). HIV gradually weakens and destroys the immune system, leaving the body defenseless against infections and certain cancers that ultimately prove fatal. AIDS represents the final stage of HIV infection, where life-threatening infections and cancers commonly occur.

HIV/AIDS reached epidemic levels in the 1980s, particularly in Africa, where the disease is believed to have originated. Factors contributing to its spread include urbanization, long-distance travel within Africa, international travel, evolving sexual behaviors, and intravenous drug use. According to a 2004 United Nations report, approximately 38 million people were living with HIV, with around 5 million new infections and 3 million deaths annually. Since 1981, an estimated 20 million people have died from the disease.

Asthma is a long-term lung condition characterized by inflamed airways that frequently narrow, leading to episodes of wheezing, breathlessness, coughing, and chest tightness. These symptoms can range from mild to severe, sometimes becoming life-threatening. The inflamed airways become overly sensitive to various triggers, such as pollen, dust mites, animal dander, air pollution, cigarette smoke, medications, weather changes, and physical activity. Stress can also worsen the condition.

Asthma attacks can start suddenly or develop gradually over days. While the first episode can occur at any age, about half of all cases appear in children under 10, with boys more frequently affected than girls. In adulthood, asthma affects men and women equally. Childhood asthma is often linked to a genetic predisposition to allergens like pollen, dust mites, or animal dander. In adults, asthma can be triggered by allergens, viral infections, aspirin, or exercise. Adults with asthma may also experience nasal polyps or sinusitis.

Cancer encompasses over 100 different diseases marked by the uncontrolled proliferation of abnormal cells in the body. It impacts one in three individuals in developed nations and remains a leading cause of illness and mortality worldwide. Although recognized since ancient times, significant advancements in cancer treatment have emerged since the mid-20th century, driven by improved diagnosis, targeted surgery, radiation therapy, and chemotherapy. These developments have contributed to a decline in cancer-related deaths in developed countries, and ongoing research into the disease's causes and mechanisms offers hope for further progress.

Advances in cell biology, genetics, and biotechnology have provided researchers with a deeper understanding of the abnormalities in cancer cells and the factors contributing to cancer development. These insights are gradually being translated into enhanced strategies for prevention, diagnosis, and treatment of the disease.

The common cold is a viral infection primarily affecting the upper respiratory tract, occasionally spreading to lower areas and potentially causing secondary infections in the eyes or middle ears. Over 100 viruses, including parainfluenza, influenza, respiratory syncytial viruses, and reoviruses, can trigger the cold, with rhinoviruses being the most common culprit.

The term 'common cold' originates from the chilliness felt during early symptoms, once mistakenly believed to be caused by cold environments. However, the illness is transmitted through contact with infected individuals, not cold weather, wet feet, or drafts. Some people can carry and spread the virus without showing symptoms. The incubation period is brief, typically one to four days, with the virus spreading before symptoms appear and peaking during the symptomatic phase.
