Top 10 World’s Most Deadly Diseases
As we are progressing, we are also making mistakes which lead to the birth of deadly diseases such as Ebola, Dengue, etc. So here, to raise awareness, we’re counting down the Top 10 World’s Most Deadly Diseases. So without further ado, let’s start.
1. Coronary Artery Disease:
The deadliest disease in the world is Coronary Artery Disease (CAD) which is also known as ischemic heart disease. This disease hit the human blood vessels and narrows the flow of the blood. The World Health Organization (WHO) has calculated that 7.4 million people died due to CAD in 2012 which was the 13.2% of total deaths. In US it took the lives of around 600,000 people according to Centers for disease control and prevention. That makes it the most deadliest in the world which takes around 380,000 lives every year.
Risky factors that can lead disease to attack the heart blood vessels are smoking, high blood pressure and high cholesterol level. Weight control, regular exercises and proper balanced nutrition can lower the risk of CAD.
A stroke is happened when an artery in brain gets blocked or leaked. Due to no oxygen supply to brain, the brain cells begin to die within minutes. According to WHO, 6.7 million people died because of stroke. This round figure was reached in 2012. This figure represents about 11.9% of total deaths. CDC figures show that 130,000 people in US died because of stroke each year. Stroke is also a leading cause of disability.
Good health habits can lower stroke risks.
3. Chronic Obstructive Pulmonary Disease:
The main cause of this disease is tobacco. Another cause is air pollution both indoors and outdoors. It happens to both men and women at the same rate. There is no cure for this disease but the progression can slow down by proper medication.
The American Lung Association calculated that 12.7 million adult died in the year 2011 in US due to this disease. So that’s why they say guys, tobacco doesn’t only cause mouth cancer, but it can also cause COPD. Be aware, stop smoking tobacco, it could lead to your death. 🙂
4. Lower Respiratory Infections:
WHO calculated that the lower respiratory infection has caused 3.1 million deaths in 2012. This group of diseases are pneumonia, bronchitis, and influenza.
Flu season lasts from December to February in Northern hemisphere and June to August in Southern hemisphere. According to CDC, 20% of travelers when returning to US seek medical attention because of respiratory infections during trips. Packed cruise ships, hotels and other close quarters increases the risk of the outbreak and transmission of this disease.
Trachea bronchus and lung cancer are all respiratory cancers. The main cause of this type of cancers are second hand smoking, smoking and environmental toxins.
WHO calculated that about 1.6 million people died due to this disease. Seriously, stop smoking guys!
HIV is a short of Human Immunodeficiency Virus that attacks the immune system. HIV can cause AIDS because of the immunodeficiency syndrome. AIDS is a deadly virus. Foundation of Research estimated almost 39 million people have died due to AIDS. In 2013 1.3 million people lost their lives because of AIDS.
By the end of year 2012, 35.3 million people around the globe were infected by this viral disease. Almost 5,700 people are infected from AIDS everyday.
Rate of this deadly disease varies in geographical location. In Sub-Saharan Africa, every one in twenty adults has HIV. 70% of total population has HIV in this region. Sadly it has highest percentage of 91 of HIV positive in children in the world.
7. Diarrhea Diseases:
Diarrhea happens when you pass two-to-three loose stools in a single day. When diarrhea last a few more days, human body losses a large amount of salt and water. Death can be caused due to dehydration. It is often caused by intestinal infection transmitted through parasites and viruses. This type of infection can spread easily through contaminated water or food.
According to WHO, 1.5 million people died by diarrhea disease in 2012. This disease is the top-killer of children that are under the age of 5. Unfortunately, 760,000 children in the world died due to diarrhea. Healthy behaviors of washing hands carefully with good bacterial soap can reduce its cause to 40%.
8. Diabetes Mellitus:
It is a group of diseases that affects the production of natural insulin in human body. In type 1 diabetes, pancreas can no longer produce insulin. Its cause is not known yet. In type 2 diabetes, the pancreas cannot produce enough insulin which is caused by number of factors like lack of exercise and over weight.
In 2012 1.5 million people died from diabetes. People from mid income countries are likely to die from complications of diabetes. Moreover, if you have this disease, your wounds will not heal properly unless your body’s insulin levels are optimal.
9. Preterm Birth Complications:
According to WHO, in 2012, 1.1 million deaths were caused due premature births. Most deaths happen in first weeks. Lack of skilled medical care for babies is a huge problem for under-developed countries. Many new born baby’s death can be avoided by good paternal and postnatal care.
Tuberculosis is a lung condition caused by a bacteria called Mycobacterium tuberculosis. It can be successfully treated when diagnosed in early stages. About 900,000 people lost their lives due to TB. The larger percentage of deaths are in poor countries. It is one of the top causes of death of the people who have HIV.
