Just as the Iran-Israel conflict is making life already difficult across the world, a new Covid variant is drawing attention again. According to a report by the University of Minnesota’s CIDRAP, the Cicada Covid variant was first detected in South Africa in November 2024 and carries around 70 to 75 changes in its spike protein compared to earlier variants. These changes may allow it to partly evade immunity built through vaccines or past infections, raising fresh questions about what comes next.

Cicada Covid variant: Are we heading into another crisis?

The emergence of any new variant often triggers memories of lockdowns and overwhelmed hospitals. But experts say the situation today is not the same as the early pandemic days. "However, just because a variant has emerged does not mean there is now another crisis as happened at the start of the pandemic," Dr. S M Fayaz, Lead & Senior Consultant - Internal Medicine at KIMS Hospitals Bengaluru told ToI.

One major difference now is widespread immunity. Many people have what doctors call hybrid immunity, protection built from both vaccination and prior infection.

"Depending on vaccines and prior COVID-19 infections, a considerable number of people will have hybrid immunity," he adds. "Additionally, the healthcare systems are much better prepared to handle respiratory outbreaks with improved access to testing, treatment protocols and antiviral therapies."

What “immune escape” actually means

The term may sound alarming, but immune escape does not mean total loss of protection. Instead, it suggests the virus can bypass some existing defences, leading to reinfections.

Dr. Fayaz clarifies, "The primary health-related consequence of this new spread is that its capacity to partially evade immunization can lead to an increase in new infections and multiple instances of reinfection."

In simple terms, more people may catch the virus again, but not necessarily fall severely ill.

How severe could infections be now?

Early indications suggest the illness pattern may resemble recent Omicron waves, especially among healthy individuals.

"Although it remains possible that both illness levels, such as mild to moderate degree of illness caused by the new variant, resemble levels of illness we have experienced over the most recent wave of the Omicron variant," Dr. Fayaz notes.

Cicada Covid Variant Symptoms

Symptoms are expected to include fever, cough, fatigue and general weakness, uncomfortable but manageable for many.

He adds, "Symptoms of recent waves of Omicron includes fever/cough/fatigue, and other symptoms that produce the appearance of still being able to respire adequately while ill-reassuringly most pertain to healthy populations... and they can expect a full year of functional health."

Cicada Covid Variant: Who should stay cautious

While the broader population may face milder illness, some groups remain at higher risk.

Dr. Fayaz points out, "The most significant concern continues to fall within certain higher-risk populations; mainly the elderly populations, people with preexisting disease conditions, pregnant women, and patients that can initiate an immune response from their medications."

For these individuals, even a less severe variant can lead to complications, making vigilance essential.

Why you should stay vigilant

As fatigue around COVID grows, experts warn against completely tuning out updates. Monitoring variants and trends remains important to avoid being caught off guard.

Dr. Fayaz says, "The new findings imply the need to maintain genomic surveillance and readiness, not panic."

That balance, staying alert without overreacting, is key to managing the current phase.

COVID-19 is increasingly behaving like a seasonal respiratory illness, with periodic spikes rather than constant waves.

"COVID-19 case surges may occur episodically, similar to flu viruses," Dr. Fayaz explains.

This shift changes how society responds, from emergency mode to long-term management.

Even now, vaccination remains a crucial defence, especially for vulnerable groups. Booster doses can significantly reduce the risk of severe illness.

Basic precautions, like testing when symptomatic and being mindful during outbreaks, continue to play a role.
