The COVID-19 pandemic has already wreaked quite a havoc throughout the world. The world as a whole is not just suffering through an economic crisis but also fighting for lives. But still, tons of discoveries about the virus are to be made. The World Health Organization has already advised with some preventive measures that one needs to take during such a crisis. People should also be vigilant regarding symptoms such as fever, dry cough, and running out of breath.
Transmission of Corona Virus
The new coronavirus can spread from one person to another within a distance of 6 feet. The transmission of the virus generally occurs through respiratory droplets that are produced by the infected person when they sneeze or cough. There is a possibility that viruses might remain at the surface of any object and enter the body through mouth, eyes, or nose.
The new coronavirus is considered to be a respiratory virus mainly due to its mode of transmission. Once the virus enters the body, that is where it starts to attack.
Symptoms of COVID-19
According to the researchers, a person can develop the symptoms of COVID-19 within a span of two to 14 days. The average number of days for being infected is considered to be five. Once the virus has successfully entered the body of the host, it starts to affect the epithelial cells. These cells are found at the lining of our lungs. The virus’s receptors contain protein which can bind themselves with that of the host. This is when the replication process takes place until the host’s cell is entirely dead.
At the initial stages of the virus attack, it infiltrates the upper respiratory tracts. The infection occurs through nasal and oral cavity along with larynx and bronchi. One can find mild symptoms of dry cough, running out of breath, fever along with acute headaches, muscle pain, and even tiredness. Some of the most uncommon symptoms include diarrhea and nausea. As the infection gradually spreads towards the lower respiratory tract, the symptoms become more severe.
Pneumonia and Other Autoimmune Diseases
According to WHO, almost 80% of all the COVID-19 infected patients had mild to moderate diseases. While the majority of them had cough and fever, they don’t require any hospitalization. But for the 13.8% severe cases and 6.1% of the critical one, the virus tends to enter into the lower respiratory tract. As the virus enters the respiratory duct, this is when respiratory problems such as pneumonia and bronchitis occur.
As the studies show, only infants, children, and older people above the age of 70 are most vulnerable to the new coronavirus. The only way to stop the chain and contain the virus from further spreading is through social distancing. Make sure to stay at home, and you will be safe. Your small contribution can help society a long way down the line.
