The term COVID-19 refers to the novel coronavirus that has wreaked havoc across the world. Right after emerging in Wuhan, China the virus quickly spread in the world, and the WHO had to declare it as a pandemic. The coronavirus is an RNA virus and ribonucleic acid is present as the genetic material in it.

How did Coronavirus Spread?

To find out how long it takes for coronavirus symptoms to develop, we can examine the first few cases that appeared in China in December 2018, which then went on spread throughout Wuhan and then the rest of the world. The first of the cases had symptoms that are similar to the ones that you get during an allergic reaction or flu. These included sneezing, dry cough, fever, etc.  The viruses of the RNA group including the MERS and the SARS have appeared before the COVID-19 turned into a pandemic. These viruses were first transmitted from animals to humans.

What are RNA diseases and what does it do to the human body?

The RNA diseases are not new to humans as they did make an appearance before and are known to affect the neurological, respiratory, and gastrointestinal systems in our bodies. These viruses usually cause infectious diseases which means that they can be transmitted from one person to another.  This can happen because two people are in close contact with each other. This contact can include actions such as coughing, sneezing, talking, or even breathing in a way that droplets from one person’s respiratory system can enter and affect another person’s respiratory system. These droplets can enter another person’s respiratory system through their nose, mouth, eyes, and ears.

From whom the Covid-19 transmission took place?

Teams of top scientists from all around the world are working to find out answers such as: Where did the virus originate from? How exactly did it transmit to humans? How does it affect the human body? For how long does it affect the person?

As far as the development and identification of symptoms are concerned, this tends to differ for every person according to how their immune system has been affected.

How long it takes for coronavirus symptoms

There are a few common symptoms, which the body starts experiencing in the early days after a person has been exposed to the virus, and it has infected him. In most cases as mentioned before, these symptoms are dry cough, fever, tiredness, etc.

In most cases, according to doctors, it takes about 4 to 5 days for the COVID-19 symptoms to show after someone has been exposed to the virus and has gotten infected, however, time can extend up to 14 days.

There is also a possibility that a person’s body does not show any symptoms at all. This means that the person is asymptomatic. This situation in particular is the most dangerous as one might transmit the virus to others without knowing that they are carrying the virus.

This is one of the reasons why the spread of the virus has been so severe and has affected every country in the world.

This is not only the case for asymptomatic persons. Every person who gets infected can transmit the virus for up to 2 days before they show any symptoms. The transmission time of the virus ranges from 1 to 2 weeks, particularly in extreme cases. This is the reason why people are recommended to get tested for the COVID-19 if they have come in contact with a person who has been exposed to the virus within a few days before the said exposure.


The newly-discovered vaccine is known to be effective in the treatment of the COVID-19 affected individual.

It is essential to get vaccinated against this coronavirus. Other than getting vaccinated, you must practice good hygiene and follow the given Standard Operating Procedures (SOPs) such as social distancing and use of facial masks in public places to prevent the spread of this virus.
