How to Detect You Have Covid-19’s Symptoms at Home

Featured Lifestyle News Slider

Covid-19 today has mutated and it is even harder for us to detect the virus as the person who contacted the virus will no more longer shows any signs of symptoms. This also means that anyone in the public area now could be a Covid-19 carrier without them know it.

Before we get into further discussion in here, we would like to state a disclaimer that we are not a medical experts and the following information that we are sharing are information that we have gathered from the news media; 8TV Evening News on 28th May 2021 and also Sunway Medical’s Home Isolation Guide R3 book.

Category/Stage of Covid-19 Infections

The current Covid-19 virus would reduce the level of oxygen in or blood overtime and eventually attack our respiratory systems when our body is weak. Based on the Ministry of Health, there are 5 category of Covid-19 infection.

The first category shows no symptoms of the infection at all on the patient. The second category shows some symptoms such as upper respiratory tract (URTI) symptoms, e.g. nasal congestion, sore-throat, cough or fever, lethargy, body-ache, anosmia (loss of smell), ageusia (loss of taste), gastrointestinal symptoms, e.g. vomiting, diarrhoea but without pneumonia.

If you are in category 3, it would shows symptoms with pneumonia but we may not need any oxygen support yet. In this stage we might also be experiencing “Happy Hypoxia” phenomenon.

Happy Hypoxia

Happy Hypoxia is a condition where the patient may not feel breathless but oxygen level might have dropped unknowingly. Happy Hypoxia situation could be detected by any blood oxygen detector that we could purchase in the medical pharmacies or with some of our fitness tracker which has SPO2 features.

Category 4 is where the patient is having Pneumonia and requires oxygen support. There would be a high possibility for the patient to also have “Happy Hypoxia” too. Once u have passed to category 5 (the final category), the patient would have multi organ failure due to insufficient oxygen and may need ventilator support for respiratory failure, dialysis for renal failure etc.

So that’s what would happen in each category. Since we are unable to detect category 1 and sometimes category 2’s symptoms, what we could do is to check on our blood oxygen level constantly to make sure that we are not being infected with Covid-19’s “Happy Hypoxia” symptoms and our blood oxygen level would not goes below 95% with the blood oxygen level detector or our fitness tracker.

Some of the fitness tracker that are able to track your Blood Oxygen Level were the latest iWatch, Samsung Watch 3, Mi Smart Band 6 and many more. If you are looking to purchase any of the above, check out the link below:

If your your Blood Oxygen Level are lower than 90%, it is time to go to the hospital.

If you develops any of the above signs, seek immediate emergency treatment. As for now, what we can do to play apart in fighting this Covid-19 virus is to Stay at Home and Stay Safe.
