COVID-19 resurges: How THIS new symptom is key to XFG, NB.1.8.1, and LF.7 variants

Time of India

a day ago

Covid 19 has made a return. Yes, after creating mayhem in the world from 2019-2022, the virus is seeing a gradual return to Asia with Singapore and Hong Kong recording the maximum number of cases in the last few weeks.
Closer home, the country has been seeing a rise in variant NB.1.8.1 and LF.7 variants, (and recently XFG) detected recently in different parts of the country. While the disease is still endemic, and (for now) poses no immediate threat according to the government, what is this new variant, and what makes it different from the rest? Let's dig deeper into the symptoms...
No need to panic, say authorities
Despite the rise in cases, most infections remain mild, and hospital ICU admissions have not surged significantly.
However, outpatient departments (OPDs) in hospitals are seeing a sharp increase in patient visits, with footfall rising three to four times over the past ten days. This indicates a rise in mild to moderate cases that require medical attention but not intensive care.
Hoarseness: A New and Common Symptom
One of the striking features of the current wave is the frequent reporting of hoarseness or a hoarse voice among Covid patients. Unlike earlier waves where loss of taste and smell were hallmark symptoms, this time many patients complain of a dry or irritated cough accompanied by throat pain and hoarseness.
Doctors from various hospitals have confirmed that hoarseness is now a common symptom seen in OPDs across India.
Are the variants more transmissible
Early data suggests that the new variants may indeed be more transmissible than previous strains. The NB.1.8.1 variant, for instance, exhibits a "growth advantage," indicating its ability to spread more rapidly. Similarly, the LF.7 variant is under observation by the World Health Organization (WHO) to determine its transmissibility and potential impact.
While detailed studies on the XFG variant are still emerging, its presence adds another layer of complexity to the current situation.
Not so severe, yet
It is important to note that increased transmissibility does not automatically translate to more severe illness. The key factors driving the spread of these variants include mutations in the virus's spike protein, immune evasion, seasonal conditions, and human behavior. Close monitoring and further research are essential to fully understand the transmission dynamics of these new variants.Experts emphasize that while these variants spread easily, they do not currently cause severe illness in most people.
However, individuals with underlying health conditions, the elderly, and young children remain vulnerable and should take extra precautions.
How effective is the vaccine
India's vaccination drive has been largely successful, with over 95% of eligible adults vaccinated and about 75% having received booster doses. However, only around 18% have received vaccines specifically designed to target Omicron strains, which may affect the level of protection against new variants.
Despite the rise in cases, vaccines continue to provide strong protection against severe disease and hospitalization. Health officials advise people to stay updated with their vaccine doses, especially those at higher risk. Children who were not eligible earlier are now encouraged to get vaccinated as they turn 18.
The central government has also formed a committee to monitor the situation closely, focusing on vaccine availability, testing capacity, hospital preparedness, and essential medicines to manage the surge effectively.
How is Covid different
With the monsoon season, respiratory illnesses like the flu are also common, making it difficult to differentiate Covid from other infections based on symptoms alone. Both flu and Covid can cause fever, cough, sore throat, headache, and fatigue. However, loss of taste and smell remains a more specific sign of Covid, although less common in the current wave.
Doctors recommend testing for Covid if symptoms like hoarseness, diarrhoea, or unexplained fatigue appear.
Early detection helps in timely isolation and treatment, reducing the risk of spreading the virus further.
What should you do
Watch for symptoms: If you experience hoarseness, dry cough, low-grade fever, diarrhoea, or throat discomfort, consider getting tested for Covid.
Get vaccinated: Ensure you and your family are fully vaccinated and boosted as per government guidelines.
Follow hygiene practices: Wear masks in crowded places, maintain hand hygiene, and avoid large gatherings.
Monitor health: Keep an eye on oxygen levels if you test positive and seek medical help if symptoms worsen.
Stay informed: Follow updates from health authorities and consult doctors if you have underlying health conditions.
