The Coruna virus has infected tens of thousands of patients around the world, however, we still know very little information about this highly contagious disease.
The outbreak of influenza-like illness, now known as Covid-19, first appeared among a group of Chinese pneumonia patients in Wuhan in late December and spread rapidly to Europe and the Americas.
The latest studies found that infected people can transmit the virus to others even before symptoms appear, and it takes about 5 days before signs such as high temperatures and cough appear.
This new strain of the Corona virus destroys the human body, which explains the risk of death for the elderly and individuals with pre-existing health conditions, and experts believe that he can live within the respiratory system for at least five weeks.
The global epidemic has led to a travel ban and the closure of borders, schools and museums in a number of places, especially in Italy, which has put its 60 million people in an unprecedented quarantine.
Researchers are still studying how the virus attacks the body, how it can be treated and whether there are any long-term effects, amidst drastic measures to limit the spread of Covid-19.
Doctors in China, specifically in Wuhan and the surrounding Hubei Province, which was the starting point for the disease outbreak, provided many answers on how the virus attacked the body.
What does the Corona virus do for the body?
The virus infects tissues and air passages deep inside the lungs, and its first symptoms are similar to the flu, which includes fever, dry cough, fatigue and shortness of breath.
Some people experience muscle pain, sore throat, runny nose or diarrhea. The disease can develop into pneumonia and respiratory failure in severe cases, at which time the patient can develop acute respiratory distress syndrome and die.
CT scans of the lungs of coronavirus patients have white spots that indicate “ground-glass opacity” or fluid, which becomes more intense over time, and was similar to those who contracted SARS or respiratory syndrome in the Middle East.
British doctors found that “pulmonary disease is fully involved” in 25 cases who underwent testing 6 to 12 days after they reported symptoms of the Coronavirus.
In general, the British Ministry of Health says on its website that typical symptoms of the Corona virus include fever and cough that may develop into severe pneumonia that causes shortness of breath and breathing difficulties, and the disease can cause more severe symptoms in people with weakened immune systems. And the elderly, and those who suffer from long-term conditions such as diabetes, cancer and chronic lung diseases.
How capable is the disease of killing those infected with it?
British health chiefs say most people who contract the virus will have only mild symptoms.
According to the World Health Organization, about 80% of patients recover without the need for specialized treatment. Almost one in every six suffers from a serious condition and breathing difficulties.
The most vulnerable people are the elderly and those with underlying health conditions (such as diabetes and heart disease).
How does the disease spread?
Experts are still investigating how the virus spreads, but it is often spread by coughing or sneezing spray from an infected person, and what can enter it through the mouth, nose, or eyes.
Virus particles invade and multiply human cells, causing the infection to spread and spread throughout the body. Once in the lungs, the virus can cause serious damage and become life threatening.
According to the researchers, the lungs can be filled with fluid and dead cells, which hinders their supply of oxygen in the blood and the removal of carbon dioxide.
Health officials said the virus could survive on hard surfaces such as plastics for up to 72 hours and soft surfaces for 24 hours.
How is it treated?
There is no specific treatment for the virus until it may take a year before the vaccine is released for public use. While health organizations stress that antibiotics do not help treat the disease, because they do not work against viruses.
And the disease needs measures to alleviate the symptoms while the body fights the disease, in addition to the need to remain in isolation, away from others, until it recovers.
