The Delta variant of COVID-19 is one type of mutation of the COVID-19 coronavirus that has been found in Indonesia. This variant was investigated by the Faculty of Medicine, Public Health, and Nursing, Universitas Gadjah Mada (UGM) based on a case in Kudus, Central Java.
According to UGM research results, it was found that 28 out of 34 or around 82% were the Delta variant (B.1.617) of COVID-19.
"Delta variant is proven to increase after their transmission between humans. And it has been proven in the population in India and in Kudus. This also strengthens the researchers' hypothesis that the increase in cases in Kudus is due to the Delta variant," said dr. Gunadi, Head of the Research Team, quoted on the Ministry of Health website.
dr. Gunadi also added his hypothesis with the latest research from The Lancet, namely the Delta variant is related to the patient's age. "The older the COVID-19 patient, the Delta variant will worsen the patient's immune system," he explained.
Symptoms of the Delta Variant of COVID-19
Common symptoms of Covid-19 reported since the beginning of the pandemic is the loss of smell or taste, persistent cough, and fever. However, reported by Sky News, the symptoms reported COVID-19 are now starting to change.
According to data collected by ZOE, headache, sore throat, and runny nose is now considered the most common symptom, rather than coughing and loss of smell or the sense of taste.
The Delta variant of COVID-19 now accounts for 91% of new cases in the UK. So, what are the most common symptoms of the Delta variant?
According to Prof Spector of ZOE, headache now the most commonly reported symptom, followed by sore throat, runny nose, and fever.
Coughs are less common, are the fifth most reported symptom, and loss of taste or smell is not even in the top 10.
1. Severe flu
For the younger population, contracting COVID-19 feels more like a "bad flu" which means some people "still go to parties and can spread it to about six other people", Prof Spector explains.
Data shows the Delta variant is "actually much more infectious than many experts thought" with recent estimates suggesting it is about twice as contagious as the original variant.
2. Not feeling well
Prof Spector also noted the current "feeling unwell" could be a reason to stay home.
Currently, symptoms of not feeling well can be one of the characteristics of the COVID-19 Delta variant, especially in young people.
"So if you don't feel well, stay home for a few days until the discomfort passes."
If you think or suspect someone close to you has COVID-19, they should isolate and get tested at the nearest clinic or order a home testing service.
As scientists gather more data on the Delta variant, including a clearer picture of the symptoms it causes, people should be on the lookout for other symptoms of coronavirus infection, such as coughing, shortness of breath, headaches, fatigue, or loss of sense of taste or smell.
