Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.
Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.
Nowadays, there are much confusion about stroke, from the symptoms and risks of this disease. Stroke is usually fatal, even life threatening. Therefore we should try to understand it better.
A stroke is a neurologic deficit or neurological phenomenon caused by a brain circulatory disorder which occurs suddenly. In general, the cause of stroke is the things that cause disturbances in the blood vessels of the brain or cause damage to blood vessels. Stroke caused by number of disorders which affect the blood vessels to blood vessel walls are thin or due to congenital abnormalities and can also occur due to blockage of blood vessels, resulting in poor blood flow circulation and eventually clogged so that a stroke occurs.
Everyone can be at risk for stroke, but the risk of stroke is higher in patients who have risk factors of stroke. Risk factors of stroke are divided into two, which are risks that can be controlled such as high blood pressure, high cholesterol, diabetes, high uric acid and heart disease and risk factors that cannot be controlled such as old age and gender. Men usually have a higher risk of stroke than women. These risk factors of stroke can aggravate the condition of the blood vessels.
Symptoms of stroke depend on the location of the damage. Our brain is like a map. Symptoms arise depending on the damaged area. For example, the left brain damage causes paralysis of the right body will caused weakness or lack of coordination in your lips, mouth and tongue muscles that may affect your voice and all occur suddenly. When the damage occurs in the right brain then the symptoms that arise is left body paralysis. Patients can even be unconscious in a sudden when brain damage occurs extensively or occurs in the brainstem area. These symptoms are sometimes followed by headaches.
Stroke can happen to anyone at any time!
Stroke is not a hereditary disease. But some risk factors of stroke are genetic disease, such as high blood pressure and diabetes. There are also people who suffered from hypertension and diabetes in their young age. But stroke can be prevented by controlling risk factors. Patients who have had a stroke are more likely to have recurrent strokes. It is important for patients who have had a stroke to implement a healthy lifestyle. Consuming healthy foods with balanced nutrients, doing some exercise, avoid smoking, regular check-up at least once a year to determine blood sugar levels and blood pressure.
