‘Transmissibility high, current Cov strain may be more dangerous for elderly, kids'
Kolkata: Small Covid surges may continue to recur for some more years, and even though they may not cause virulent infections, transmissibility could be high, putting the elderly and children at risk, said doctors and experts in Kolkata.
Those with comorbidities were particularly vulnerable now since the seemingly innocuous cough-and-cold that the prevailing strain has been triggering may transform into fatal pneumonia for those above 65, they warned.
Most Covid positives in Kolkata are elderly with comorbidities, and children, with several suffering from respiratory diseases. Those with diabetes, COPD, cardiac diseases, or chronic kidney ailments were at risk, said CMRI Hospital pulmonology director Raja Dhar.
"Typically, these patients are above 65 and have lower immunity. So, if a member of the family has Covid, which may not trigger symptoms more severe than a cough and a runny nose, the elders need to be isolated.
For those with comorbidities, even this mild infection could be fatal," he said.
Charnock Hospital is assessing the situation to stay "prepared for any potential escalation", though none has yet tested positive at the hospital.
"So far, it seems the strain is a variant of Omicron that triggers mild symptoms like flu. We haven't yet seen the typical Covid pneumonia, though several have had respiratory symptoms. Those with lower immunity, and kids must be careful," said Charnock pulmonologist Soumya Sengupta.
The hospital has revived the use of hand sanitisers and masks on its premises and is in the process of setting up isolation wards and ICU beds.
The emergency department has started screening patients.
BP Poddar Hospital has expanded its patients' waiting area to minimise crowding, and is planning to reinstate its isolation ward. "The currently circulating variant poses a significant risk to those with comorbidities like diabetes, hypertension, chronic lung or kidney disease, or weakened immunity," said Rajdip Sen, consultant physician at BP Poddar Hospital.
Elderly people with multiple comorbidities are immunosuppressed and should use masks, continue daily medications, and maintain hand hygiene, said ILS Hospital pulmonologist Mrinmoy Mitra. "If those with chronic lung diseases develop fever, cough, breathlessness, wheezing, or chest tightness, they should consult a pulmonologist," he said.
It is time to revisit vaccines and check if the ones used during Covid remain effective, said Dhar, adding: "There is no reason to panic but keep your guards up."

Bihar had lowest sex ratio at birth in 2022, in decline for three years: CRS data
Bihar has recorded the lowest sex ratio at birth for 2022 among all States and Union Territories, reporting just 891 girls born for every 1,000 boys, according to the Civil Registration System's vital statistics report, released this week by the Office of the Registrar General of India. Bihar is also the only State that has seen its sex ratio at birth declining consistently since 2020, the year from which this data is available for the State. In 2020, the State reported a sex ratio at birth of 964, which fell to 908 in 2021, before further dipping to 891 in 2022. This comes ahead of the Bihar Assembly election, at a time when political parties have been actively targeting women voters, including with promises of cash transfers in polls in Haryana, Maharashtra, and Jharkhand. In 2024, 47.6% of Bihar's 7.64 crore electors were women, though voter turnout in the State during the 2024 general election showed that 50.4% of votes polled came from women. Other States with low sex ratios at birth in 2022 were Maharashtra (906), Telangana (907), and Gujarat (908). On the other hand, Nagaland had the highest figure of 1,068, followed by Arunachal Pradesh (1,036), Ladakh (1,027), Meghalaya (972), and Kerala (971). Assam, which had reported 863 girl babies born in 2021 for every 1,000 boys, the lowest ratio for that year, showed an improvement to 933 in 2022. Delayed reports A month after the Office of the RGI released the Civil Registration System (CRS), Sample Registration System (SRS), and Medical Certification of Cause of Death (MCCD) reports for 2021, after a four-year-delay, the government this week released the CRS and MCCD data for 2022 as well. However, the SRS report for 2022 has not yet been made public. The SRS is the largest demographic survey in the country, meant to provide annual estimates on fertility and mortality indicators, including birth and death rates. The CRS and MCCD reports provide data on registered births and deaths, and the causes of medically certified registered deaths respectively. Drop in deaths in 2022 The CRS report showed that there were 86.5 lakh registered deaths in 2022, a stark drop from the 102.2 lakh registered deaths in 2021, the year in which the COVID-19 pandemic took its highest toll in the country. The Hindu has previously reported on how the 2021 data, recording 'excess deaths' in comparison to the norm, showed that the initial government reporting of COVID-19 deaths for the year was an underestimate. The CRS 2022 data also showed a hike in registered births, rising to 254.4 lakh registered births, in comparison to 242 lakh the previous year. Birth, death registration trends State-level birth registration statistics in the 2022 report show that, since 2013, States like Uttar Pradesh, Bihar, Madhya Pradesh, Telangana, and Uttarakhand have seen a general trend of registered births rising, despite occasional dips. On the other hand, States and UTs like Tamil Nadu, Kerala, Himachal Pradesh, Punjab, and Delhi saw a general decline in registered births, despite fluctuations. Of the total registered births in 2022, 52.4% were boys while 47.6% were girls. While about 43% of the births were registered in rural areas, 56.5% were registered in urban areas. The report added that the number of registered stillbirths in 2022 fell to 1.15 lakh from 1.24 lakh the previous year. Of the total registered deaths in 2022, the shares of men and women were 60.4% and 39.6% respectively. The report showed that 59.5% of the registered deaths were in rural India while 40.5% were in urban areas.

No need to panic because of rising Covid cases, just be cautious: Dr Wali
New Delhi, June 7 (UNI) The Covid cases are rising rapidly and the deaths have alerted us but there is no need to panic, prominent doctor Mohsin Wali has said. Dr. Wali, who has had the unique privilege of serving three Presidents of India -- R. Venkataraman, Dr. Shankar Dayal Sharma, and Pranab Kumar Mukherjee -- said most of the people infected with the virus will have mild to moderate respiratory illness and will not require special treatment. While the potency of the current strain of the Covid virus has increased slightly, there is no need to panic, he says, adding people should, instead, be cautious about its transmission and follow Covid-appropriate behavior. 'This is a respiratory virus, a sars virus, and the current variant is a sub-variant of Omicron. Its spike protein has changed, and it has increased its ability to bind to cells. However, we need to fear not the virus itself but its transmission," he said. 'Fearing transmission means we need to wear masks, use sanitizers, maintain social distancing, and follow covid-appropriate protocols. We should not go directly to (interact with) small children or elderly people after coming home from outside," he suggested. "If you have cough, cold, and fever for more than three days, get tested for covid. If the test is positive, don't panic. Isolate yourself and follow the doctor's advice," he added. People with asthma, cold, and fever along with heart or kidney disease should be cautious and those who have undergone kidney or liver transplant should also be careful. "We don't need to do anything more than this. The government is monitoring it, and whenever there is another variation, it will be caught," he says. UNI AM AKK BM

Bhopal: The reports of 11 samples from suspected Covid-19 patients were received on Saturday; all tested negative. Overall, a total of 9 new COVID-19 cases were reported in Bhopal since April this year. In April, there was 1 case, in May 3 cases, and in June 5 positive cases were identified. Currently, there are 4 active cases. One patient was hospitalised due to other illnesses and tested positive for COVID during those examinations. Three individuals, who were asymptomatic, were advised to stay at home and take precautions. Five individuals recovered and are symptom-free, said official sources. Continuous monitoring is being conducted to ensure the infrastructure and delivery of health services, sources said. Recently, mock drills were organised in health institutions to evaluate the supply of medical oxygen and the efficiency of oxygen plants. Dr Prabhakar Tiwari, CMHO Bhopal, stated that health institutions have been instructed to follow protocols based on symptoms. Free consultations are available at all govt health institutions. The public is urged to seek medical advice for testing and treatment if needed. Avoid self-diagnosis and self-medication. There is no need to fear COVID, but caution is necessary. COVID can be dangerous for individuals with low immunity, such as cancer patients, dialysis patients, and those with co-morbidities like diabetes, so they should take special precautions, he said.
