Five most Common Diseases
Five most Common Diseases: The World Health Organization estimates 12,420 distinct diseases and medical conditions as of 2011.
In other words, before you go to bed, you should thank your immune system and modern medicine every night.
Among all of those illnesses, infectious diseases—which the WHO defines as “any harmful microbe that can be transmitted straight or indirectly from one person to another”—may be the most prevalent.
- Hepatitis B affects about 2 billion people worldwide, or more than one-quarter of the world’s population, making it the most prevalent infectious disease.
- This condition, characterized by liver inflammation that causes fatigue, nausea, and jaundice, can have long-term effects, including liver cirrhosis or liver cancer.
- The main focus of concern is on the estimated 350 million people who have the chronic form of the illness.
- In tropical and subtropical climes, malaria, a mosquito-borne illness that disproportionately affects children.
- Affects more than 500 million people annually and kills between 1 million and 3 million people, according to the World Health Organization.
- It seems to be the second most prevalent infectious disease after hepatitis B and has one of the highest yearly mortality rates.
- Although there has been some progress in raising public awareness of the risks posed by mosquitoes in tropical and subtropical regions, malaria numbers have recently begun to climb.
- Hepatitis C is a less mutual and less severe type of disease, but unlike hepatitis B, it almost usually progresses into a chronic condition rather than an acute one.
- One hundred eighty million people worldwide experience this chronic illness, which over time can progress to liver cancer or cirrhosis of the liver despite only 3–4 million new cases being recorded year.
- These are the times we curse mosquitoes since the Aedes aegypti mosquito, a highly particular species, transmits dengue to roughly 50 million people annually.
- Dengue is most prevalent in Africa and Asia; thankfully, only mild to moderate variants exist.
- These types can produce high fevers, excruciating headaches, and severe joint and muscular pain but seldom result in a patient’s death.
- As I’ve already indicated, estimating new and ongoing cases for any of these illnesses may be challenging, and tuberculosis is probably the most challenging.
- The bacteria that causes TB is present in the lungs, where it can cause chest pain, a dry cough, as well as other unpleasant side effects.
- In terms of a single infectious agent, it is also the second largest cause of death worldwide, behind AIDS.
- TB knowledge and prevention aren’t where they need to be in low- to middle-income countries. Where the bulk of TB-related deaths (95%) occur.
- The decent news is that TB death rates are down globally. However, 8.6 million new cases of the disease were reported last year, and over one-third of the world’s population has latent TB.
- Which income they have the infection but are not yet unwell and cannot spread the disease.
