Corona virus (COVID-19) disease



Corona viruses are a group of viruses that can cause diseases such as colds, severe acute respiratory syndrome (SARS) and the Middle East Respiratory Syndrome (MERS). A new type of corona virus has been discovered after it was identified as the cause of the spread of one of the diseases that started in China in 2019.

The virus is now known as Corona 2 (SARS Cove 2). The resulting disease is called corona virus 2019 (COVID-19). In March 2020, the World Health Organization announced that it had classified the 2019 Corona virus (COVID-19) as a pandemic.

Public health groups, such as the Centers for Disease Control and Prevention in the United States (CDC) and the World Health Organization (WHO), monitor the pandemic and post updates on their websites. These groups have also made recommendations about disease prevention and treatment.



Corona virus disease signs and symptoms 2019 may appear 2 to 14 days after exposure, and may include: 



Shortness of breath or difficulty breathing

Other symptoms may include:



Runny nose

Sore throat




Some patients also felt a loss of sense of smell and taste.

The symptoms of corona virus 2019 symptoms can range from very mild to severe. Some people may never have symptoms. Older people or those who already have medical conditions, such as diabetes, heart and lung disease or a weakened immune system, may be more likely to develop severe disease. This is similar to what happens with other respiratory diseases, such as influenza.


When do you visit the doctor?

If you develop symptoms of Corona Virus 2019 (Covid-19) or have contact with someone who has been diagnosed with it, contact your doctor or clinic immediately for medical advice. Before going on schedule, tell the health care team about your symptoms and the possibility that you have been exposed to the virus.

If you have urgent signs and symptoms associated with corona virus 2019, such as difficulty breathing, chest pain or pressure, confusion, or bluish lip or face, seek care immediately.

If you have respiratory symptoms but are not present in areas where there is persistent local spread and you do not go to these areas, contact your doctor or clinic for instructions. Tell your doctor if you have other chronic medical conditions, such as heart or lung disease. As the epidemic increases, it is important to ensure that health care is provided to those most in need.


The reasons

Infection with the emerging corona virus (scientifically labeled as severe acute respiratory syndrome Corona 2, or SARS Cove 2) leads to corona virus 2019, which is referred to briefly as Covid-19.

It is unclear exactly how capable the new SK virus infection is between people. The data showed that it spreads from person to person through close contact (within 6 feet, or 2 meters). The virus is spread by respiratory droplets released when the infected person coughs, sneezes or talks.

It can also spread if a person touches a surface on which the virus is infected and then touches his mouth, nose, or eyes.


Risk factors

The risk factors associated with Corona virus 2019 (Covid-19) seem to include:

Recently residing in one of the areas that has experienced a persistent community spread of Corona virus 2019 or a recent arrival from a trip to those areas, according to the areas defined by the Centers for Disease Control and Prevention or the World Health Organization.

Close contact with a person who is infected with HIV 2019, such as when a family member or health care worker takes care of an infected person.


Although the symptoms of most people with corona virus 2019 (Covid-19) vary from mild to moderate, the disease can cause severe medical complications and lead to death in some people. Older adults or those with chronic medical conditions are more likely to develop a serious case of corona virus 2019.


Complications can include:

Inflammation of both lungs

Several organ failures


Although a vaccine is not available to prevent the emergence of the new corona virus, you can take steps to reduce the risk of infection. The World Health Organization and the Centers for Disease Control and Prevention in the United States recommend the following precautions to prevent Covid-19:

Avoid attending large events and gatherings.

Avoid close contact (within 6 feet or 2 meters) with anyone who is sick or has symptoms.

Keep a distance between you and others if Covid-19 is prevalent in your community, especially if you are at greater risk of developing an acute degree of illness.

Wash your hands frequently with soap and water for at least 20 seconds, or use a hand sanitizer that contains at least 60% alcohol.

Cover your mouth and nose with your elbow or a tissue when you cough or sneeze. Dispose of the napkin after using it.

Avoid touching your eyes, nose, and mouth.

Avoid sharing dishes, drinking glasses, bedding, and other household items if you are ill.

Clean the surfaces most frequently touched daily.

If you are sick, stay at home and do not go to work, school or university, and the same applies to public places, unless for the purpose of obtaining medical care. Avoid using public transportation if you are sick.
