Expert Speaks on Diagnosis, Treatment, Vaccination Of The COVID JN.1 Variant
India has been seeing a surge in the number of COVID-19 cases for the past few weeks. Along with that, the country also reported cases of the new JN.1 variant of COVID-19. This new variant belongs to the Omicron family and has an additional spike protein which makes it more transmissible.
Dr. Sapna Yadav, Senior Consultant, Pulmonology at Sarvodaya Hospital, Greater Noida sheds light on diagnosis, treatment, vaccination, and preventive measures for the new JN.1 variant of COVID-19.
“Current JN.1 strain is a variant of OMICRON strain of COVID-19, although it spreads more easily, it causes milder illness in the majority of individuals. Prevention is the most effective way to deal, hand hygiene, use of masks and appropriate vaccination is the key,” she said.
Dr. Yadav also said that this variant has similar properties like that of the previous Omicron strains, however, this one has a distinctive mutation in its spike protein. She said, “While demonstrating high transmissibility and mild symptoms, it appears to be more adept at evading the immune system and spreading more easily. However, there is currently no evidence suggesting increased severity or higher fatality rates compared to other variants.”
Speaking of symptoms, Dr. Yadav said, “Patients infected with the JN.1 variant may experience initial symptoms such as fever, runny nose, sore throat, headache, and, in some cases, moderate gastrointestinal problems. Breathing difficulties may also occur in certain patients.”
COVID-19 PCR testing in conjunction with clinical symptom assessment is what she recommends for diagnosis of the condition.
“Risk factors for infection include advanced age, male sex, smoking, and pre-existing conditions such as COPD, diabetes, hypertension, coronary artery disease, and malignancy.
“Treatment remains supportive, with antivirals such as Paxlovid, molnupiravir (Lagevrio), and remdesivir (Veklury) recommended for individuals at high risk of severe illness with mild to moderate symptoms, according to CDC guidelines.
“The World Health Organization (WHO) assures that current vaccines continue to protect against severe disease and death from the JN.1 variant and other circulating COVID-19 variants.”
Dr. Yadav also emphasizes on the importance of maintaining protective measures, including mask-wearing, practising respiratory etiquette, regular hand hygiene, staying up to date with vaccinations, and staying home when sick.
To safeguard against all SARS-CoV-2 variants, Dr. Yadav recommends adhering to preventive measures such as wearing masks in crowded areas, practising respiratory etiquette, regular hand hygiene, staying up to date with vaccinations, and staying home when exhibiting symptoms or after exposure to the virus.
Dr. Sapna Yadav underscores the significance of halting the spread of the virus to prevent the emergence of further variants, reinforcing the collective responsibility to curb the pandemic.
