The threat of COVID has not subsided yet. In China, Europe, and Southeast Asia cases of Covid-19 have started increasing again. And surprisingly, in China, which has adopted a zero-COVID strategy, more than a thousand cases are coming daily in the last few days. Here, about 30 million people are isolated in their homes. Moreover, according to health specialists at Asthma Bhawan, not only in China but also in other countries, Omicron is wreaking havoc. What are BA.4 and BA.5 sub-variants of Omicron? Symptoms and Precautions
Recently the whole world faced the third wave of coronavirus. And the biggest reason for the third wave was Omicron, which considers being the fastest spreading variant of COVID ever. Although the World Health Organization (WHO) considered it a matter of concern, researchers say that although its symptoms are mild, it has the potential to infect anyone quickly.
What are BA.4 and BA.5 sub-variants of Omicron? Symptoms and precautions | How Omicron Variants lead to a COVID surge in India? – Asthma Bhawan
Omicron Sub Variant BA.4- There has been a significant decline in the cases of coronavirus infection. Meanwhile, another sub-variant of the Omicron (BA.4 variant) was recorded in India. This variant is found in Hyderabad and is the first case of this variant in the country. And this variant was recorded in the covid-19 Genomic Surveillance Program.
After getting this variant, the scientists said that this variant might be found in other parts of the country. Let us tell you that this strain of SARS At first, the CoV-2 virus was recorded in South Africa. After this, this variant was also found in other parts of the world. Furthermore, this infection is considered fatal, which can affect vaccine success.
How deadly is BA.4?
- The presence of BA.4 in the world is low as of now. As of March 16, there have done four sequencing of the strain. It is the number of sequencing in the GISAID database. The belief is that the actual number of BA.4 is extended because BA.1 and BA.2 become uncontrolled.
How is BA.4 born?
- According to health experts, BA.4 consider from the combination of BA.1 and BA.3. And Ba.1 is the parent Omicron, and Ba.3 is the sub variant.
Two mutations in BA.4
- 4 has two mutations, one in the NSP15 (N11S) and the second in the N-terminal domain of the spike protein (L212I). Furthermore, these mutations result from the subsequent recombination of BA.4.
Symptoms of BA.4 and BA.5 sub-variants of Omicron
Covid care hospital in India said they identified four cases of BA.4 and BA.5, and all infected people were between the ages of 30 and 50. All these people have received both doses and are showing mild symptoms. During this summer season, symptoms are hard to identify quickly. It is because the symptoms of Delta-chrome or BA.2 are similar to those of common summer disease. Scientists believe that if a person has been infected with the Omicron variant of the corona, he doesn’t need to develop immunity to the BA.2 variant as well. What are BA.4 and BA.5 sub-variants of Omicron? Symptoms and Precautions
Delta-chrome or BA.2 spreads much faster than Omicron. And some reports claim that it spreads up to 70 times faster. Delta-chrome is a hybrid strain consisting of Delta and Omicron. At the same time, BA.2 is a variant of Omicron, although the symptoms are also the similar, and chronic. Many diseases like diarrhea, vomiting, and headache are common in the summer. So, it would be difficult to differentiate the symptoms of Delta- chrome or BA.2 from them. The World Health Organization (WHO) has warned not to take this variant of the corona lightly because it has the potential to spread more rapidly.
Most recorded Symptoms in BA.2 patients
- Fever or chills
- Difficulty breathing
- Loss of taste or smell
- Sore throat
- Runny nose and discomfort
- Vomiting or nausea
- Muscle or body pain
What are the Symptoms of Delta-chrome?
- High fever and subsequent sweating or chills
- Sore throat
- Persistent cough
- Fatigue or lack of energy in the body
- Loss of smell or taste
From the past few months, omicron has changed rapidly. Experts believe that Omicron’s sub variants may become a matter of concern. As of now, there are no cases of alpha, beta, gamma, and Delta old variants of the corona. On the other hand, there has been an increase in the case of Omicron and its sub variants. Because of the increasing COVID case in many countries of Asia, and it is a matter of worry that the fourth wave of corona may come anytime.
How fast do all these variants spread?
WHO says they have start tracking BA.4 and BA.5 because more studies are need to understand the additional mutations they cause to the human body.
And last week, Britain’s Health Security Agency report that BA4 detect in South Africa, Denmark, Botswana, Scotland, and England between January 10 and March 30. At the same time, all the cases of BA.5 were report from South Africa only last week.
How severe are all the variants?
Infected people have been record with only mild symptoms in sub-variants. But most of the infected people got both doses of the vaccine. To date, the cases of these two sub-variants are not increasing rapidly. Moreover, no death has been record from these two sub-variants so far.
Experts believe that new sub-variants are likely to be less lethal, but people must follow the COVID protocol to protect themselves. At the same time, it is too early for experts to say how the mutation of these two new sub-variants will affect the corona epidemic.
What is the threat to India from the sub-variants?
The third wave is over in India. But in the last few days, corona cases are increasing in many states. During the third wave, omicron’s sub-variant in India was the BA.2 dominant variant, and many cases belong to it. As like before, the flight service is on. In this condition, it will be a risk that new variants of corona can travel from abroad to India. So, keep updated yourself What are BA.4 and BA.5 sub-variants of Omicron? Symptoms and Precautions
How can we protect?
To protect against every variant of the corona, it is necessary to follow the COVID protocol. Make sure to wear a mask covering your mouth and nose. Maintaining social distance from others, keep a distance of at least one meter. Avoid living in crowded places and places with poor ventilation. Take care of adequate ventilation in the house, even indoors. Wash hands regularly with soap and uses sanitizer when you can’t wash your hands. Get both doses of the vaccine. Nine months after the second dose, a booster dose should also be advisable. What are BA.4 and BA.5 sub-variants of Omicron?
However, Indian scientists say that large populations are vaccinate in India, and anti-bodies form in many people. And they can fight with corona, so this variant will not have much effect.
According to health experts of Asthma Bhawan, immunity made from the vaccine lasts only six months (maximum), and the number of people in India who vaccinate for more than six months. And now, the effect of the vaccine is decrease. Therefore, people in the country are at the highest risk of getting infect with any new variant. and keep update yourself about What are BA.4 and BA.5 sub-variants of Omicron? Symptoms and Precautions
