Highly Mutated Cicada COVID-19 Variant Spreading Across US: Key Symptoms Revealed

A new, highly mutated variant of COVID-19, nicknamed Cicada, is reportedly spreading across the United States, raising fresh concerns among health experts. While surveillance is ongoing, early observations suggest that this variant carries multiple mutations that may affect transmissibility and immune response, making it important for the public to stay informed. According to the CDC, Cicada is a subvariant of Omicron subvariant, BA.3.2, and has had detections in wastewater across at least 25 states. First identified in late 2024, it carries 70 to 75 spike protein mutations. While it is under monitoring, early evidence suggests it does not cause more severe disease than previous strains.Also read: Frequent Nosebleeds? It Could Be High Blood

What is the Cicada COVID-19 variant?

Experts say Cicada has accumulated a high number of mutations, particularly in the spike protein, the part of the virus that helps it enter human cells. Mutations can sometimes make a virus spread more easily, evade immunity from past infection or vaccinations, and lead to slightly different symptoms. However, experts stress that research is still evolving, and not all mutations lead to more severe disease.

Key symptoms to watch out for

So far, symptoms linked to the Cicada variant appear similar to previous COVID-19 strains, but with some variations reported:

• Persistent sore throat
• Runny or blocked nose
• Fatigue and body aches
• Mild fever or chills
• Headache
• Dry cough

Some patients have also reported gastrointestinal symptoms like nausea or diarrhoea, which have been intermittently seen in earlier variants as well. Most importantly, symptoms may be milder in vaccinated individuals, but this does not eliminate the risk of transmission.

Why are experts concerned?

Experts say they are closely monitoring this variant due to its high mutation profile. A heavily mutated strain raises concerns about increased spread within communities, potential reduction in vaccine effectiveness, even though protection against severe disease usually remains, and the risk of reinfection even among those previously infected. Despite these concerns, there is no clear evidence yet that the Cicada variant causes more severe illness than earlier strains. As with previous waves, certain groups remain more vulnerable, including older adults, those with chronic illnesses like diabetes, heart disease, or lung conditions, and individuals with weakened immune systems. For these groups, even mild infections can lead to complications, making preventive care essential.

Ways to protect yourself

While early detection and isolation can help limit the spread of emerging variants, experts recommend continuing basic COVID-19 precautions, especially in crowded or poorly ventilated spaces:

• Stay up to date with vaccinations and boosters
• Wear masks in high-risk settings
• Maintain hand hygiene
• Avoid close contact if you feel unwell
• Test if symptoms appear

While new variants like Cicada may sound alarming, they are part of the natural evolution of viruses. Public health systems worldwide continue to monitor changes closely and adapt strategies accordingly. The emergence of the Cicada variant is a reminder that COVID-19 has not disappeared. Staying informed about symptoms, risks, and preventive measures remains key to protecting yourself and your community.
