Corona Virus Disease 2019, “COVID-19” was recognized as the greatest challenge humankind had to face since World War 2. Today, during COVID-19 pandemic all nations help each other in pursuit of formulating effective vaccines and medicine.
COVID-19 is a highly infectious disease reason why many people had lost their lives with the death poll still rising. The virus is said to have started in Wuhan, China at the end of 2019 causing large scale outbreak throughout the whole world.
Data from published epidemiology and virology studies provide evidence that COVID-19 is primarily transmitted from symptomatic people to others who are in close contact through respiratory droplets, by direct contact with infected persons, or by contact with contaminated objects and surfaces.
Although the COVID-19 defies prediction, scientists as well as medical experts are expressing the possibility of the human immune system ability’s to fight the virus.
Patients who recovered from the COVID-19 pandemic had shown signs of developing antibodies, which works by neutralizing the virus, blocking its reproduction thus leading to destruction.
Studies show that the white blood cells help in developing the antibodies which usually takes about a week or longer in mild COVID-19 cases.
Vaccine makers are paying close attention to the B cells and T cells respond to the virus. B cells help make the antibodies to fight against the virus while T cells kill the infected cell either directly or indirectly. Some T cells also play as helper cells because they help B cells make the target antibodies.
In a study, it is observed that the antibodies of the COVID-19 survivors with severe cases are fading after a viral infection. However, survivors of milder cases show that the antibodies count is still rising after three months.
The results showed the promising sign that the immune response to the novel coronavirus does not seem to be different from other known viruses.
Who are More Susceptible to the Virus?
The virus can be fatal to patients who already have respiratory problems then affected it since it will damage the lungs even more.
Older people are also prone to get easily infected by the virus, especially elders who have underlying conditions such as diabetes, heart disease, cancer, and others.
Medical experts advise people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene.
