COVID-19 Symptoms and their types

Coronavirus Disease 2019 (COVID-19)is a viral infection of the respiratory system that is common in animals but rare in human beings. Coronaviruses are a group of viruses that have six different strains that can cause infections in humans. Among which three human coronaviruses produce potentially severe symptoms. 

Those three viruses are;

  • The Middle East respiratory syndrome-related Coronavirus (MERS-CoV), β-CoV (first case identified in Jeddah, Saudi Arabia)
  • Severe acute respiratory syndrome coronavirus (SARS-CoV), β-CoV (First case identified in Shunde, China)
  • Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), β-CoV (First case identified in Wuhan, China)

Luckily, MERS and SARS Coronaviruses did not turn out as a pandemic. They were controlled. Plus, the symptoms were not that much severe.

SARS-CoV-2

The SARS-CoV-2 virus is a strain of the coronavirus family that causes an infectious disease of Respiratory tract. The first case was identified in Wuhan, China on 17 November 2019 that results in an ongoing pandemic.

This virus infected more than 7.66 million people in around 188 countries. Resulting in more than 400,000 deaths and 3.63 million recoveries.

Symptoms

From common flu to severe shortness of breath, there are several types of symptoms. For better understanding, the doctors divided into three categories.

  • Mild
  • Moderate
  • Severe

Mild Symptoms 

According to WHO-China Joint Mission on Coronavirus Disease 2019 (COVID-19), around 80% of people only get mild to moderate symptoms.

 A person with mild symptoms may have;

  • Fever for few days
  • Common flu
  • Sore throat 
  • Dry cough
  • Body aches and pains
  • Some respiratory symptoms

Though, one can not have all the above symptoms at once or right after getting infected. The virus may take 14 days to show all or a few of the above signs and symptoms.

In case, if you are having mild symptoms, you really do not need to run to the hospitals as most of the cases with mild symptoms recover on their own.

 It is only dangerous for people aged above 50 and for those who already have some sort of medical issues.

You need to be extra careful if you or someone near you is showing these mild signs of COVID-19, and is older in age. Because such cases may develop moderate symptoms and may need some medical assistance in a hospital.

Moderate Symptoms

A COVID-19 positive patient with moderate symptoms may have;

  • A fever above 100.4 degrees
  • Cough
  • Chills
  • Affected sense of smell & taste
  • Shortness of breath 
  • Dehydration (dry mouth, increased thirst, decreased urine output, dry skin)
  • Headache
  • Dizziness
  • Tiredness/ Mussels and body aches
  • Loss of sense of smell & taste 

While having the symptoms above, one must get assistance with a medical healthcare provider, whether s/he is a suspected or a confirmed COVID-19 patient.

Severe

If a person has developed all moderate symptoms along with pneumonia, s/he is considered to be in a severe condition of coronavirus disease. 

When a COVID-19 patient gets pneumonia, his/her immune system tries to fight back and tries to kill the virus, as a result, the antibodies start destroying the lungs cells along with the virus.

 On the other hand, in severe condition, the virus also starts replicating itself inside the human body. And that may cause dysfunctioning of other vital organs. 

Acute symptoms and response of the immune system may impair the potential to make the blood oxygenated that may result in organ failure.

When to Consult a Doctor

Coronavirus symptoms start showing up in between a 14-days time period. The Best possible practice is to avoid going outside unnecessarily. For a safer side, in case if you feel any of the symptoms above, isolate yourself and consult a medical adviser online.

Do not take medications that are circulating on social media. Every person has a different medical history and one can show allergies and reactions to some medicines. 

During this pandemic, many online healthcare services have been introduced. Use this digital technology instead of rushing to the hospital with mild symptoms.

Most importantly, if your symptoms start getting worse or you feel shortness of breath. Don’t wait for anything and rush to your nearest medical emergency center. 

Ending Words

We tried to elaborate the symptoms and signs of this infectious disease in terms of mild, moderate and severe. These all are intelligent terms for awareness. Do not use these terms straight while visiting your healthcare provider. Instead, use the proper words for your symptoms such as fever, flue, etc.
