What are the symptoms of the Delta Variant, Delta Plus Variant and Mu Variant strains of the emerging coronavirus “Covid-19”? What are their mutations? And what is the best way to prevent them? The answers in this comprehensive report .

We start with the symptoms of the strains, which are also called variants, and then move on to the other details.

First, the symptoms of the new strains of Corona are among the previous known symptoms of the Corona virus, which you can view by clicking on this link.

On the other hand, there are some symptoms that distinguish a particular strain from others, and we will present them after referring to several scientific and news sources such as "Yale Medicine", "UC Davis Medical Center" and "It This Not That" ( Eat this not that) and Parade.

We point out that these symptoms are indicative, and to make sure of your injury, always consult a doctor.

Here are these symptoms:

Delta strain symptoms

  • Runny nose

  • sneezing

  • headache

  • Sore throat

  • cough

  • fever

  • Loss or change in the sense of smell or taste

  • diarrhea

  • Abdominal pain

  • nausea

    • Symptoms of the Delta Plus strain

  • dry cough

  • Tired

  • fever

  • shortness of breath

  • Abdominal pain

    • Mo . strain symptoms

    The symptoms of "Mo" are similar to the symptoms of the original virus, and they are:

  • Muscle and body aches

  • Loss of sense of smell and taste

  • cough

  • shortness of breath

  • Sore throat

  • Tired

  • fever or chills

  • headache

  • Congestion or runny nose

  • Nausea or vomiting

  • diarrhea

    •  The delta strain is called "B.1.617.2" (B.1.617.2), and Dr. Lorena Garcia, assistant professor of epidemiology at the University of California, Davis School of Medicine and chair of the graduate group in epidemiology, says that the delta variable is different from Covid. -19 is original in that it is more portable.

    This strain is highly contagious, and was first identified in India in December 2020. The delta strain affects more people who are not immunized.

    Delta strain can be disastrous in some societies, as in societies with low vaccination rates, particularly rural areas with limited access to care, the delta variant can be more harmful.


    A mutation affecting the spike

    Delta Plus strain is also called Delta AY.1 and B.1.2.617.1 (B.1.617.2.1), and this strain includes the K417N mutation, which is A mutation first found in a "beta variant" that appeared in South Africa.

    “Delta Plus has one extra mutation for what the delta variant contains,” says Dr. Insi Yildirim, a pediatric infectious disease specialist at Yale Medicine and a Yildirim vaccine specialist.

    She added that this mutation, called "K417N", affects the "spike" protein that the virus needs to infect cells, and this is the main target of "mRNA" and other vaccines.

    As for the "Mu" strain, its scientific name is "B.621.1" (B.1.621).

    It is one of these variables that health experts are watching because it has appeared in certain parts of the world.

    Dr. Jessica Shepherd said - in a statement to Bared - about the Mu variant that scientists are watching to see if this particular type has the ability to invade immunity.

    She adds that scientists are monitoring it to make sure that it will not spread all over the world, as this is what happened with the delta variable;

    It started in India, and over time we've seen it move across the country to other countries.


    How prevention?

    • Vaccination. People who have been vaccinated are usually either asymptomatic or have very mild symptoms if they have been infected with a delta strain, or other strains.

    • Maintain social distancing.

    • Wearing a mask, especially in crowded places.

    • Wash hands and apply hygiene procedures.
