What are the less common symptoms of COVID 19

Since last year, the COVID-19 pandemic has opened our eyes in many areas, economically, financially, emotionally. It proves that even though we have all the richness today, without health, it is all wasted, thus the saying goes, health is wealth.

 Throughout this pandemic, we can learn many new things on a day to day basis, starting from proper hand hygiene, our surroundings, alertness and many more. Why do people learn this? It is because, once infected with the COVID-19 ( Coronavirus disease ) many things might and will happen. For example, the common symptoms such as cough, fever, flu, difficulty in reathing. The question today is ( soalan ) is there any other symptoms that can happen other than the common cold symptoms? The answer is YES!


            Before we go through the less common symptoms of the Coronavirus also known as COVID-19, let's briefly go through the common symptoms that most people know today.

Fever, dry cough, flu, difficulty in breathing, muscle aches, chills, sore throat, headache, chest pain. These are the common symptoms as for now what we know today. Respiratory symptoms are the most common symptoms, but in fact it can also involve other organ systems. What are the less common symptoms?


  1. Gastrointestinal Symptoms


         Let's start with the Gastrointestinal symptoms. It is known that COVID-19 causes nausea, vomiting and/or diarrhea. It can happen with the common symptoms or without it. These symptoms tend to appear first before the respiratory symptoms. How does COVID-19 cause nausea? It happens because the ACE2-mediated reacts with the SARS-COV-2 and invades the gastrointestinal epithelium, and starts replicating leading to the decrease in ACE2 levels and causing decrease in organ protection resulting in the increased inflammation and decrease in it’s function.Therefore, vomiting and nausea is caused due to the COVID-19 virus attacking the gastrointestinal tract.


  1. Loss of sense of taste and smell


            This symptom is more common than the other less common symptoms with almost a large number or patient having it. Patients having these symptoms do not have nasal congestion associated with it. Experts believe that the loss of sense of taste and smell will return after you have been cured within 30 days but there are a handful of people that are still suffering with this symptom even after being cured more than 5 months ago resulting with smell and taste therapy to try to return their sense. It is believed that patients who suffered with these symptoms and their sense did not return is because the nerve pathway has been damaged by the virus. The virus enters into the epithelium/mucous membrane and interferes with the nervous pathway, blocking the nerve endings, resulting in inability to pass information to the brain.


  1. Skin Symptoms


            These symptoms appear most commonly in children and adolescents. The common symptoms associated with this condition are swelling, discoloration, blisters, itchiness, painful raised bumps and rough skin. A small amount of pus may also form beneath the skin. These symptoms normally can last from 10 to 17 days, or even months after recovery. Normally, the swelling on the fingers and toes could also be confused with chilblains, a type of inflammatory skin condition.


  1. Central Nervous System Symptoms


            For this system, confusion also known as delirium in the medical terminology is the main or might be the only symptom of COVID-19 in olderly patients. There are two types of delirium, there are hyperactive delirium and hypoactive delirium. Hyperactive delirium is when the patient is suffering with delusion or hallucinations. Hypoactive delirium on the other hand is when the patients appear sleepy, responds slowly and is not communicating with others. In some rare occasions, it is possible to have a mix of both in certain patients.


            In conclusion, all these symptoms listed above are some of the lesser common symptoms of the Coronavirus known as COVID-19 these days. It is not impossible in fact quite common that some patients only exhibit the less common symptoms than the common one, some might only be a carrier without any symptoms. It is vital to get yourself checked regularly to ensure your COVID-19 free.
