How Does COVID-19 Affect Our Body?


The current coronavirus death toll is 4990, with confirmed 134,919 cases around the world. As seen in news, the virus can be seen spreading at a fast pace, alarming everyone to take precautions to protect ourselves from this pandemic.

How exactly does the coronavirus affect our body?

Since COVID-19 shows several characteristics related to the Severe Acute Respiratory Syndrome (SARS), scientists are using facts about SARS to teach people about COVID-19.

COVID-19 affects the lungs at first, and spread through the water droplets generated as a person sneezes or coughs. (Wear a face mask so that you’re safe at least from people coughing and sneezing on you while in public places.)

Once affected, COVID-19 attacks the human body in three steps:

  1. Viral replication
  2. Immune hyperactivity
  3. Pulmonary destruction

It is in the upper respiratory tract, according to researches, that COVID-19 replicates.
During the incubation period, which is 5.1 days, no symptoms are shown, making the spread of the virus easier. Once infected, while immune cells start attacking the virus, sometimes the virus causes the immune system to generate overreactive responses.

COVID-19 infection happens in three phases:

  1. Mild illness with upper respiratory tract symptoms
  2. Non-life-threatening pneumonia
  3. Severe pneumonia with acute respiratory distress syndrome, which might demand life support.

Symptoms that can be commonly seen in COVID-19 patients are fever, dry cough, fatigue, with some experiencing joint pains, runny nose, or diarrhea.
Moreover, 80% of the affected people are able to fight COVID-19 with no special treatment.

People are demanding a response from the US government through the public letter written collaboratively by around 450 public health and legal experts. It is advised that medical personnel are fully equipped with the necessary equipment and facilities to attend the situation. Further, opting for telecommuting wherever possible, with paid sick leave allowed for employees is a measure that needs to be applied at an emergency situation like this.

In any case, the best steps to be safe from COVID-19 lie on our hands, literally.

Deep cleansing of hands.
Using tissues to cover coughs and sneezes.
Keeping household and workplace clean.

Stay safe, people!
