5. If you're under home quarantine instead, monitor your illness daily

'Happy' hypoxia is a condition where COVID-19 patients experience low oxygen levels in their blood but may not necessarily feel short of breath. 

To keep track of your oxygen levels, you can buy or borrow a pulse oximeter approved by the Medical Device Authority Malaysia (MDA).

However, if you experience difficulty breathing, loss of speech or mobility, or your condition is deteriorating rapidly, contact 999 immediately.

Happy hypoxia って言うとは知らなかった。

低酸素症になっていても　息苦しさを感じない場合、自覚症状がないので　ハッピーということから命名されているんだろうか。

Oximeter はAmazonで購入した。

Happy Hypoxia is when a Covid-19 patient has a very low level of oxygen as shown on the monitor, but appears to be breathing more or less normally.

In a series of videos on the Health Ministry's Facebook page on Thursday (June 17), it said that among the symptoms of the condition or when oxygen levels were less than 91% included breathing difficulties, headaches, dizziness, skin turns bluish, and cold palms.

Dr Mohd Noor Akmal who is attached to the ministry said that the young who were healthy were most at risk for the condition.

He said the condition occurred when there was an infection in the lungs.

"The Covid-19 virus causes infection in the tissues of the lungs, causing damage to it. Teenagers, young people, and the healthy do not display any symptoms because they have high immunity... what they don't realise is that the oxygen levels in the blood decreases because of lung damage. This is termed Happy Hypoxia," he said.

酸素レベルが91%以下の場合は　特に注意だ。
