Around the world, there are many diseases that people didn’t know exist. In the past decade, there have been new diseases that scientists still don’t have a cure for. For example, cancer. Cancer has been around the world for a long time. Doctors and scientists are trying to figure out a cure for cancer. Nobody has been successful yet. Global citizens have been raising money for scientists to help them invest in finding a cure for cancer.

Diseases spread fast. These past few weeks the coronavirus, for example, has spread all over China. People are in quarantine and scientists are trying to find a cure and helping people to survive. The coronavirus has spread far away from China now. The virus has taken people ever since. This virus has infected people from Asia, Europe, and the Middle east. There are only a few cases  in the US. Officials say that it’s not if but when the virus is going to infect the US more than it already did.

The most-well known diseases are ischemic heart diseases, strokes, and trachea, bronchus and lung cancers. Ischemic heart disease occurs when the blood vessels that supply blood to the heart become narrowed. It can cause chest pain, heart failure, and arrhythmia. Many of you probably do know what strokes are. A stroke occurs when an artery in your brain is blocked or leaks. This causes the oxygen-deprived brain cells to begin dying within minutes. During a stroke, you feel sudden numbness and confusion or have trouble walking and seeing. If left untreated, a stroke can cause long-term disability. Trachea, bronchus, and lung cancers can affect anyone, but they’re most likely to affect those who have a history of smoking or tobacco use. Other risk factors for these cancers include family history and exposure to environmental factors, such as diesel fumes. Aside from avoiding fumes and tobacco products, it isn’t known if there’s anything else that can be done to prevent lung cancers. However, if you catch it early, it can improve your outlook and reduce the symptoms of respiratory cancer.
