COVID-19 cases dip in India: What doctors say about risks, new symptoms and safety
India, among many other countries across the globe, witnessed a sudden rise in COVID-19 cases. Triggered by four new Omicron sub-variants—LF.7, XFG, JN.1.16, and NB.1.8.1—several fresh cases emerged across India until Friday. On 20 June, positive cases witnessed a gradual decline. While the daily case numbers are dropping and the overall severity has remained low, health experts caution that the situation is far from over.
India's active COVID-19 caseload dropped to 5,976 on Friday, marking a decline from 6,483 cases reported the previous day.
Narayana Health City's Dr Nidhin Mohan from general medicine told Livemint, 'New COVID-19 variants tend to spread more rapidly and may be less responsive to existing vaccines.'
According to doctors, these new sub-variants are highly transmissible but have not shown signs of causing more severe illness than earlier strains. The similarity is that those with compromised health and kids are at risk.
Dr Michelle Shah, Pediatric Lifestyle Medicine Specialist, pointed out, 'These four sub-variants (LF.7, XFG, JN.1.16, and NB.1.8.1) are part of the evolution of the Omicron lineage. What we're seeing is increased transmissibility. JN.1.16, a descendant of the widely circulating JN.1, has shown dominance in India. All these mutations are adept at immune escape, which is why reinfections occur, even in vaccinated individuals. However, vaccines continue to offer robust protection against severe disease and hospitalisation.'
The new strain comes with mild symptoms-- fever, continuous cough, loss of appetite or razor-blade sore throat.
"By and large, symptoms are mild. Patients with fever, cough or red nose were particularly affected," shared Dr Umang Agrawal, who handles infectious diseases at P. D. Hinduja Hospital & Medical Research Centre, Mahim, Mumbai.
'Mild doesn't mean negligible. People should watch for prolonged fatigue, chest discomfort, shortness of breath, or high-grade fever lasting more than 3 days. Also, if someone feels better and then worsens after a few days, that could be a sign of a secondary infection or post-viral inflammation. In children, elderly and immunocompromised, even low-grade symptoms warrant medical attention,' warns Shah.
'Typical current symptoms are very similar to the common cold: sneezing, runny nose, sore throat, dry cough, and mild fever. Some also experience a persistent cough that interrupts sleep, fatigue, or shortness of breath or chest discomfort (which anyone with existing conditions should be concerned about). In some cases, COVID symptoms are not even respiratory symptoms at all: gastrointestinal symptoms or neurological symptoms. Rarely, there can be mild clotting issues,' explains Dr Raja Dhar, Director & HOD of Pulmonology at The Calcutta Medical Research Institute.
Despite mild symptoms, medical professionals warn that long-term effects are still not fully understood.
'The concern around long COVID or post-COVID syndrome remains in the conversation, but it has certainly had lower proportions of the diseased assessed as milder. When we looked at the studies during the earlier Omicron waves, about 20 per cent of people reported long-term symptoms. However, that number has now decreased. Many will still experience some residual effects of fatigue, muscle pain, changes to mood, and changes to sleep, which are typical residual symptoms following many viral infections. While not completely absent, the risk of longer-term complications with these newer sub-variants appears to remain low,' Dhar noted.
Since January, over 100 COVID-related deaths have been reported in India, mostly among those with pre-existing health conditions. This highlights the ongoing danger for the elderly and immunocompromised.
'It's a reminder that for vulnerable groups, COVID-19 is still very much a threat. Pre-existing conditions like heart disease, diabetes, and compromised immunity greatly increase the risk of complications, even from supposedly 'mild' variants. We need to ensure these individuals are prioritised for early treatment,' Shah observed, underscoring the risky attitude of those putting their guards down after the decline in COVID-19 cases.
Kerala, Gujarat, Karnataka, and Delhi have seen more cases than other regions. Experts attribute this to factors like higher population density, increased testing, and more frequent travel.
'All these states have almost always been among the first to witness a surge in COVID cases through all waves, including Omicron, primarily because of a high degree of intrastate and interstate movement, urban density, and travel, both domestic and international,' says Dhar.
Doctors advise people should continue following basic precautions to protect themselves and others.
During any surge in cases, one must be extra cautious, especially in public and crowded places.
Annual COVID vaccination is necessary, particularly for high-risk groups.

5 years on, Sassoon hospital awaits approval for additional beds at 11-storey building
Pune: Five years since admission to patients began in the 11-storey building at BJ Medical College and Sassoon General Hospital (BJMC & SGH), approval for 504 additional beds is awaiting official approval from the state's medical education and drugs department (MEDD). The building houses the paediatric, pulmonary, orthopaedic and radiology departments. It has affected recruitment of staff to handle these additional patients and funds needed to buy medicines and consumables, officials at the BJMC & SGH said. They added that once the file is approved by MEDD, it will be sent to the state finance department for final approval. The building was planned in 2009 after the swine flu epidemic but took 11 years to construct. When the Covid-19 pandemic struck, the building was thrown open on an urgent basis to admit serious patients. Dr Eknath Pawar, dean at BJMC & SGH, said, "As of now we are working at 66% of staff strength at the hospital and medical college. For the hospital's old buildings, we have an approval for 1,296 beds and for that we have an approved staff strength of 3,091." As per the information obtained from the hospital, of the 2,359 approved posts for class 1-4 employees at the old buildings, only 1,565 are filled and 794 are vacant. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Thị trường có dấu hiệu suy thoái không? IC Markets Đăng ký Undo Of the 732 approved posts for BJ Medical College, 424 are filled and 308 are vacant. Dr Pawar said, "We had in 2022 sent a proposal seeking approval for 504 beds at the 11-storey building and also the staff required for those beds. We are yet to get a response on it. About the vacancies in the approved posts, we have already issued a tender to fill in the class four posts and in the next two months, 350 workers will be recruited. For class 1 and 2 posts, recruitment process is under way via the Maharashtra Public Service Commission. " The acute shortage of staff gravely affects patient services. Maya Jagtap, who has her relative admitted at the 11-storey building's orthopedic department ward, said, "Often there are no nurses or class 4 workers available to take the patient from the ward to the radiology department for scans. We have to be near the building all the time so that we can help our kin." Hasan Mushrif, minister of medical education, said, "I will look into it and if the approval is pending at our level, I will get it done in one week. I will immediately follow up on the proposal with the secretary of MEDD." Dheeraj Kumar, secretary, MEDD, could not be contacted for his comment despite several attempts. Rajiv Nivatkar, commissioner, MEDD, said, "I am out of town now; I will get back when I have information." City-based health activist and an alumnus of BJ Medical College, Dr Sanjay Dabhade, said that first it took 11 years for the 11-storey building to be constructed and then it was opened only when the Covid-19 pandemic broke out and now govt is delaying approving the beds. "The hospital is always struggling to manage the existing patient load but with additional patients coming in, it will soon reach a breaking point. Why should it take five years to approve the beds which are already in use? This hospital is not only the hope for serious patients who come from different districts of Maharashtra but also for many homeless and poor people. Without enough staff, patient services are hampered gravely and there would be constant conflict between patients and healthcare workers. State govt must immediately approve these beds and the staff required," he said.

3rd Covid death: Ludhiana under the microscope.
Ludhiana: Local health authorities are ramping up Covid-19 testing and preparedness after the district recorded its third virus-related death on Thursday, raising concerns about rising cases and the vulnerability of those with underlying health conditions. An 82-year-old man from the Samrala Road area died at a private hospital near Sherpur Chowk, the health department has reported. Officials concerned have said that the patient, who had a history of cardiac problems, was admitted on June 15 and died of acute myocardial infarction (heart attack). A Covid-19 test conducted after his admission returned positive. The patient had no recent travel history, and his daughter, with whom he lived, has not exhibited symptoms. Civil surgeon Dr Ramandeep Kaur confirmed that all three Covid-19 deaths in the district involved patients with comorbidities, and two occurred at a hospital in Chandigarh. "We are geared up already to check Covid-19, and have issued advisories to the public," she said. Health department officials have directed ground staff to increase testing of suspected cases and to remain vigilant. Of the three reported Covid-19 victims, two were elderly and one was middle-aged, officials have said. Four patients are hospitalised currently: one is on intermittent oxygen support, two are stable without support, and one is a chronic kidney disease patient. As of Friday, Ludhiana has reported a total of 64 Covid-19 cases since the start of the recent wave, with four new cases confirmed on Friday. The latest cases include two males, aged 51 and 65, and two females, aged 42 and 63, all from urban areas. Also, 34 patients have completed home quarantine, while 27 remain active cases — 23 of whom are isolating at home. Medical experts are urging residents, those with existing health issues especially, to take extra precautions. Dr Dheeraj Aggarwal, president of the Ludhiana chapter of the Indian Medical Association, warned that people with comorbidities are at higher risk of infection and should avoid social gatherings, practise frequent hand washing, and maintain physical distance. He also recommended a nutritious diet during the monsoon season to help maintain immunity. MSID:: 121977194 413 |
