Understanding the ‘nimbus’ COVID-19 Variant and Rising Cases
Table of Contents
Cairo, Egypt – Health authorities in Egypt have issued an alert regarding a newly circulating COVID-19 variant, dubbed “Nimbus,” officially known as NB.1.8.1. The Egyptian Pharmaceutical Authority is closely monitoring the strain, first identified by the World Health Organization in May, to assess its spread and potential impact. This comes as concerns grow about a potential summer surge in cases.
What is the Nimbus Variant?
The NB.1.8.1 variant, commonly referred to as Nimbus, is a recent mutation of the omicron variant. It emerged due to changes in the virus’s genetic makeup, a natural process for viruses, particularly those that are widely disseminated. The variant is distinguished by a spike protein mutation, which experts believe may contribute to its increased transmissibility.
Such mutations appear when the virus evolves, which is normal for viruses, especially those that spread widely.
Symptoms of the Nimbus Variant
According to the Global Alliance for Vaccines and Immunization (Gavi), the symptoms associated with the NB.1.8.1 variant are largely consistent with those of previous Omicron strains. The five most frequently reported symptoms include:
- Runny nose
- Headache
- Fatigue
- Sneezing
- Sore throat
Some reports suggest the variant may also cause hoarseness. Additionally, individuals have experienced gastrointestinal symptoms, including nausea, vomiting, diarrhea, heartburn, bloating, stomach pain, and constipation, tho these have not been definitively confirmed through scientific studies.
did You Know? The ACE2 protein, a key component in how the virus enters human cells, is more readily bound by the Nimbus variant, possibly contributing to its increased spread.
how Quickly Does Nimbus Spread?
While the Nimbus variant doesn’t appear to cause more severe illness, its increased transmissibility is raising concerns. The NB.1.8.1 variant exhibits a heightened affinity for the human ACE2 protein, which the virus utilizes to enter cells. This increased binding is attributed to seven mutations in the spike protein, the part of the virus responsible for cell entry.
Protecting Yourself from the Nimbus Variant
Health officials strongly recommend that individuals at higher risk of severe COVID-19 infection receive updated vaccinations. This includes those aged 65 and older, individuals with underlying chronic medical conditions, and pregnant women. The Centers for Disease Control and Prevention (CDC) advises annual updated doses for these vulnerable populations.
additional preventative measures include wearing masks in indoor settings, practicing social distancing, frequent handwashing, and ensuring adequate ventilation.
Pro Tip: Staying informed about local health guidelines and recommendations is crucial for protecting yourself and your community.

COVID-19: A Continuing Evolution
The emergence of the Nimbus variant underscores the ongoing evolution of SARS-CoV-2, the virus that causes COVID-19. Viral mutations are a natural process, and continuous monitoring is essential to understand the potential impact of new variants on public health. The development and deployment of updated vaccines remain a critical strategy in mitigating the spread and severity of the disease. Long-term surveillance and research are vital to anticipate and respond to future variants effectively.
Frequently asked Questions about the Nimbus Variant
- What is the Nimbus COVID-19 variant? The Nimbus variant (NB.1.8.1) is a new strain of the COVID-19 virus, a sub-lineage of Omicron.
- How contagious is the Nimbus variant? Early data suggests the Nimbus variant is more transmissible then previous strains due to mutations in its spike protein.
- What are the symptoms of the Nimbus variant? Symptoms are similar to Omicron, including runny nose, headache, fatigue, sneezing, and sore throat.
- Is the Nimbus variant more severe? Currently,there is no evidence to suggest the nimbus variant causes more severe illness.
- How can I protect myself from the Nimbus variant? Vaccination, masking, social distancing, and good hygiene practices are effective preventative measures.
