Diseases and conditions

For example, if a person dies at the age of 65 from a disease, and would probably have lived until age 80 without that disease, then that disease has caused a loss of 15 years of potential life. YPLL measurements do not account for how disabled a person is before dying, so the measurement treats a person who dies suddenly and a person who died at the same age after decades of illness as equivalent. In 2004, the World Health Organization calculated that 932 million years of potential life were lost to premature death.

The misuse of basic definitions in epidemiology is frequent in scientific publications. The benefit that outweighs the harm of any interventions taken – removing the precancerous tissue prevents cancer, and thus prevents a potential death from cancer. Common symptoms are wheezing, coughing, chest tightness, and shortness of breath. During an asthma attack, the sides of the airways in the lungs swell and the airways shrink, making it harder to breathe. Pertussis, also known as whooping cough, is a highly contagious respiratory disease.

But inflammation is damaging when it occurs in healthy tissues or lasts too long. NIEHS is committed to conducting the most rigorous research in environmental health sciences, and to communicating the results of this research to the public. A plague, caused by the bacterium Yersinia pestis, is a disease that affects humans and other mammals. People typically get infected after being bitten by a rodent flea that is carrying the bacterium or by handling a plague-infected animal. Malaria is a mosquito-borne infectious disease caused by the bite of female Anopheles mosquitoes, which spread infectious Plasmodium parasites into a host. The WHO estimates that in 2020 about 240 million people had malaria and about 627,000 of them died.

Saltwater nasal sprays (e.g. NaSal or Ocean) can ease nasal congestion and thin mucus. However, excessive use of medicated nose sprays, like Afrin, can cause dependence and may make congestion worse. If any problem is causing you discomfort, you should seek medical conditions. Because it is very difficult to avoid certain allergens, medication may be necessary to lessen symptoms caused by allergens, other than food and drugs.

Although there are several over-the-counter medications that advertise gas relief, they do not work for everyone and may have side effects. Medications that have been shown to effectively reduce gas use simethicone, a substance that helps gas be expelled through belching or passing flatus. While these medications are good for short-term immediate relief, the best step for long-term comfort is to find out what causes you gas. Mononucleosis is an illness caused by the Epstein-Barr virus, which is spread through saliva. Develop suddenly, accompanied by a fever over 101°F and are not relieved by acetaminophen or aspirin, especially if there is pain or stiffness in the neck. Over-the-counter drugs, such as Imodium A-D, should only be used if absolutely necessary because it is important to let diarrhea flush out the bacteria or parasite that’s causing the infection.

They are spread through direct contact with the bodily fluids of a sick person and can cause fever, headache, muscle pain, weakness, fatigue, diarrhea, vomiting, stomach pain, and hemorrhage. Escherichia coli (E. coli) bacteria live in the intestines of people and animals and are key to a healthy intestinal tract. Coli strains are harmless, but some can cause diarrhea through contact with contaminated food or water while other strains can cause urinary tract infections, respiratory illness, and pneumonia. Chronic diseases – such as heart disease, cancer, diabetes, stroke, and arthritis – are the leading causes of disability and death in New York State and throughout the United States.

People with allergies have especially sensitive immune systems that react when they contact allergens. Health Topics, MedlinePlus descriptions of most diseases, with access to current research articles. In studying diseases, epidemiology faces the challenge of defining them. Especially for poorly understood diseases, different groups might use significantly different definitions. Without an agreed-on definition, different researchers may report different numbers of cases and characteristics of the disease.
