The number of cases of COVID-19 is again rising globally. The novel Covid variation, NB.1.8.1, dubbed Nimbus, has generated worry, notably in the United States. Although this virus variant is a sub-variant of Omicron, certain of its distinctive signs are generating a lot of discussion. Reports claim that razor blade throat, a symptom of this novel variation, causes the throat to feel like it's being cut by a razor.

A Novel Form of COVID-19

According to Fox News, the Centers for Disease Control and Prevention (CDC) estimated that the variant accounted for around 37% of cases in the United States during the two weeks that ended on June 7. Due to the virus's severe impact on the throat, the new strain of Covid is called "Razor Blade Throat." The pain in the throat is excruciating, and it feels like a razor blade is lodged there. According to news accounts, those who have been afflicted by this variation report that the throat discomfort is so severe that it impairs their ability to speak, eat, and even drink water. According to them, anything they swallow feels like shards of glass! Signs of a sore throat have been linked to Covid infection even before this, but the issue is far more noticeable with this variant.

The terms "Nimbus" and "Stratus" are not scientifically recognized names for Covid-19 variations in India or elsewhere in the world. They are likely unofficial names for existing Omicron subvariants, which are still highly contagious but cause mild sickness. Although India's COVID scenario is presently stable, with few instances (100–200 each day) and few hospitalizations, seasonal viruses (H3N2, adenovirus) are driving an increase in respiratory illnesses in monsoon weather. The public should only follow the recommendations made by the Health Ministry and the ICMR. To distinguish between the flu and Covid-19 and make sure that high-risk populations receive a booster vaccine, they should test for severe symptoms using RT-PCR," says Dr. Arup Halder, Consultant Pulmonologist at CK Birla Hospital.

According to researchers at the Indian Council of Medical Research (ICMR), these novel strains are not causing the illness to become more severe than the previous Omicron. It is important to know what this new Nimbus variety is, what its possible risks are, and what its symptoms are.

What are the signs of the novel Covid variant NB.1.8.1?

1. "Razor blade throat" is one symptom of this variety, and it refers to throat pain that is as intense as if one has ingested a razor blade or piece of glass. Previous iterations of Covid-19 produced sore throats, but the pain in Nimbus is so severe that it may be difficult to even drink water.

2. Jaw, behind the ear, and upper back pain: In addition to throat pain, older forms of Covid-19 also caused body pain, but some patients with this variant have also reported stiffness in the jaw, behind the ear, and upper back. Unlike a typical cold, this symptom wasn't present in previous forms of COVID-19.

3. Unexpected loss of appetite: A sudden loss of appetite has been seen in addition to other signs. When certain patients have no appetite, it might exacerbate their frailty.

4. Chronic nasal blockage: This type of nasal congestion is more common than a runny nose, and it may cause breathing problems.

Other signs of Covid-19 infection include:

According to Dr. Vikas Mittal, a pulmonologist at C. K. Birla Hospital, the symptoms of Nimbus are comparable to those of previous COVID-19 variants, but certain individuals are also experiencing allergy-like symptoms. The typical symptoms are as follows:

1. Weariness

2. A temperature or chills

3. Headache

4. Physical discomfort

Are this variation risky?

The NB.1.8.1 variant does not cause severe sickness, but older individuals and those with underlying conditions should exercise more caution, according to Dr. Mittal.

How can Covid-19 be prevented?

Wear a mask: In crowded areas, always wear a mask.

Practice good hand hygiene by washing or sanitizing your hands.

Seek treatment if symptoms arise: Get a Covid test performed if you have severe throat pain or other symptoms.

Get vaccinated: If you haven't already, get your Covid-19 vaccine.

Maintain social distance: If you want to lower your chance of contracting a Covid-19 infection, it's best to do this.

Maintain solitude: If you contract an illness, keep yourself away from other people.
