6,237 tested positive for tuberculosis in Madurai district in 2024; males most affected
Besides, 1,809 cases were detected in the first three months of this year, with health officials saying TB is more prevalent in the district among men.
As per records, in 2023, 5,879 new cases were detected in the district, and the total number of people cured stood at 4,719 (87% treatment success rate). Similarly, 6,075 tested positive in 2022, and the treatment success rate was 88% (3,761 cured).
Dr Rajasekar, Deputy Director of Medical Services (Tuberculosis), Madurai, told TNIE, "In Madurai district, besides a majority of the TB patients being men, the disease is prevalent among the age group of 15 to 65 years, as they travel to many places and also play a role in spreading the infection."
Under the Nikshay Mitra scheme, the officials have carried out screening for tuberculosis across the district, along with the support of donors, who offered support to the patients, including nutritional aid (food baskets), diagnostic assistance, and vocational training. Till 2024, 114 volunteers were involved in the district under the scheme.
On the role of immunity in the spread of the disease, Rajasekar said, "According to their immune status, 5-10% of the infected individuals, who had contracted tuberculosis through airborne transmission, develop the disease. Thus, the disease is common among the elderly, people with uncontrolled diabetes, HIV patients, and those taking immunosuppressants. So, we take into account the friends or relatives who are closer to the TB patients for screening."
In the urban areas, mobile diagnostic units were sent to factories, garment showrooms, and construction sites. Officials said around 440 camps were held in Madurai, and 16,086 X-rays were taken for the purpose. As a result, 82 new TB cases were identified in 2024. An official from health department said, "Under the TN-KET scheme (Tamil Nadu Kasanoi Erappila Thittam) 267 patients suffering from severe infection were identified and were admitted as inpatients. Besides, 20 NAAT (Nucleic Acid Amplification Test) centres also played a significant role in TB diagnosis in the district."
Explaining that the disease could either be drug sensitive or drug resistant, Rajasekar said, "The treatment period for patients with drug-sensitive TB is nearly five months, whereas for those with drug-resistant TB, where the infection has spread to the nervous system, the treatment could take up to two years."

No ray of hope for patients as official machinations stall BMT at Odisha's SCB MCH
Meanwhile, the state health administration seems to be engaged in what appears to be an elaborate ploy of delay and diversion. On July 11, when the Orissa High Court took note of a TNIE news report on the situation of BMT at SCB MCH, state Health secretary Aswathy S, appearing virtually, assured that steps are being taken to restart the procedure immediately under the supervision of a retired faculty of AIIMS-Bhubaneswar Dr PK Das. One associate professor and two assistant professors of the clinical haematology department are technically qualified to conduct the bone marrow transplant and will be mentored by Dr Das to restart BMT, she told the court. But the plan has not moved an inch since. And, here lies the catch: BMT is not a short-term skill, it requires at least a year of intensive hands-on training under strict international protocols. What is worse and contrary to the submissions of the Health secretary in the high court is the SCB MCH's admission that none of the faculty members of the haematology department including the above three possess any formal training, experience, or certification in BMT procedure. Citing this, the SCB MCH superintendent has written to the DMET seeking facilitation of training process including selection of institute and finances. However, sources said, 'Restarting BMT on the basis of fresh training will take a minimum of one year, possibly more. By then, many more Saritas will be lost.' Meanwhile, Health minister Mukesh Mahaling and the Health secretary also do not seem to be on the same page. Despite the minister, in a recent note to the secretary, directing expeditious steps for re-engagement of Prof Jena in the larger interest of patients, patient care and haematology students, no action has been forthcoming. As per usual practice, a professor after retirement is re-engaged on contractual basis for at least a period of four years till he attains 70. In case of Prof Jena, the Health department relieved him after just one year in March this year. Health secretary Aswathy S did not respond to calls and messages from TNIE for her comments on the issue.

Blood donation guide: Eligibility, myths, medications, and safety tips
If you're between 18 and 60 years old, weigh at least 45 kg, and have a haemoglobin level above 12.5 grams per decilitre (g/dL), you are eligible to donate blood in India. Men can donate blood every three months, while women should wait four months between donations. However, not everyone qualifies. Dr Amita Mahajan, Senior Consultant at Indraprastha Apollo Hospitals, explained that people with chronic illnesses like heart disease, cancer, and certain infections are typically not eligible. Those on specific medications—such as antibiotics, blood thinners, or chemotherapy drugs—may also need to defer donation. Smokers and those with tattoos can still donate. Just ensure the tattoo was done at a certified centre (or wait one year if it wasn't). Also, avoid alcohol for at least 12 hours before donating. Does blood donation make you weak? This is one of the most common myths. 'There's no weakness. It's only in the mind,' said Dr Krishna Kumar Rai, Head of Emergency Medicine at Fortis Escorts Hospital, Faridabad. Dr Amita Mahajan added, 'Your body replenishes the donated blood within days. There's no long-term impact on your strength or immunity.' The key is to stay hydrated, have a light meal beforehand, and avoid strenuous activity for a few hours afterward. Is blood donation safe? Yes, blood donation is completely safe when done at certified blood banks and hospitals. According to Dr Rahul Bhargava, Principal Director at Fortis Memorial Research Institute, donors might feel mild fatigue or light-headedness briefly, but serious complications are extremely rare. Modern practices ensure safety through strict hygiene and single-use sterile needles. For recipients, risks of transfusion-related infections like HIV or Hepatitis have significantly reduced due to advanced screening protocols. Can you donate blood if you are on medication? It depends. Dr Sangeeta Agarwal, Director of Transfusion Medicine at Fortis Memorial Research Institute, said that people taking vitamins or managing controlled blood pressure or diabetes (without insulin) can usually donate. However, if you're on antibiotics, steroids, antidepressants, chemotherapy drugs, or blood thinners, it's best to consult a doctor. Always disclose all medications to the blood bank team during pre-screening—they'll guide you accordingly. Can women safely donate blood? Yes, women can and should donate blood. There are no gender-based restrictions. However, they should avoid donating during menstruation and wait four months between donations. 'Women are often wrongly discouraged from donating blood,' said Dr Rai. 'The truth is, women's bodies are just as capable of handling blood donation as men's.' Can you donate blood after recovering from Covid-19? Yes. If you've recovered from Covid-19 and are feeling well, you are eligible to donate blood. Dr Rai stressed that there is no stigma or risk of transmitting Covid-19 through blood donation. 'If you're fully recovered, you're welcome to donate and save lives,' he said. How should you prepare before donating blood? Here's a simple checklist: Stay well-hydrated Eat light, healthy food about an hour before Avoid alcohol for at least 12 hours prior Skip heavy workouts before and after donation Avoid smoking two hours before and after donating Carry a valid ID and disclose any medications to the medical staff What are the benefits of donating blood? Besides saving lives, blood donation offers emotional and potential health rewards. 'It's like a noble high,' said Dr Rai, who donates every year on his birthday. Some studies suggest that regular donors may enjoy improved heart health and reduced oxidative stress. Above all, it fosters a sense of purpose. 'Every healthy person eligible should donate,' said Dr Sangeeta Agarwal. 'You never know whose life you could save—your friend, a stranger, or a colleague. Blood banks only work when we all pitch in.'

‘Target is to stop spread': Screening camps at Delhi's urban slums strengthen fight against TB
Sheela Devi (48), a resident of Indira Kalyan Vihar, a jhuggi jhopri cluster in Southeast Delhi's Okhla Industrial Area Phase-1, stepped out to buy vegetables when Subhash, the village head or pradhan as they call him, asked her to visit the TB screening camp operating from his office. The screening was long overdue, she thought to herself. She has been suffering from fever for the last few months and coughs excessively. 'There is a persistent cough and fever which doesn't fade away,' she added. Her X-ray showed abnormalities and cavities in her lungs. 'Now, we will send her to the Nehru Nagar centre where her sputum samples will be collected for further evaluation,' explained District TB officer Dr Umesh Kumar. The village head has lent his office space for a screening camp under the Delhi government's TB programme for free for a month. A team of doctors, under the National TB Elimination Programme (NTEP), are screening patients with the help of a handheld X-Ray machine and AI software, which identifies abnormalities in the lungs and is said to have minimal radiation exposure. According to the 2019-2021 National TB Prevalence Survey, Delhi was identified as having the highest TB prevalence in India, with 747 cases per lakh population. Under the NTEP, Delhi has been conducting screening drives in urban slums and has started the first phase of the programme targeting six high-burden areas — Nehru Nagar, Narela, Karawal Nagar, Moti Nagar, Babu Jagjivan Ram Memorial Hospital's chest clinic and Shastri Nagar. In Nehru Nagar, five areas have been targeted — Indira Kalyan Vihar, Jaitpur, Pul Prahladpur, Nizamuddin and Batla House. To drive engagement, doctors and volunteers also conduct door-to-door drives, and announcements are made on loudspeakers as well. Five X-ray machines have been set up in each camp in the slums of South Delhi. 'The programme has been functioning since last December, and we started again in June this year. Our target is to stop the spread of TB, and we need to do catchment at the mass level. Except pregnant women and children below 15 years, everyone else is being screened,' Dr Umesh explained. Since June, more than 10,000 people have been screened, and around 40 people have been identified as TB affected at such camps across the city, said sources. Along with the mass-level screening, these camps provide prevention therapy to people who are at high risk — they collect the medicines from the nearby DOT centre, a healthcare facility focused on tuberculosis. 'Before prescribing medicines under TB prevention therapy, we confirm about latent TB infection by the Cy-Tb test, a modern skin test for detecting Mycobacterium tuberculosis infection, a bacterium that causes tuberculosis. If it is positive in TB contact persons, we give them the preventive therapy,' underlined Dr Umesh Kumar. For this, the doctors deployed are particularly targeting the high-risk group, which includes patients with diabetes, those with alcohol or cigarette addiction, those who are not gaining weight and those who are living in families where someone had TB in the last five years. The camp at Indira Kalyan Vihar Jhuggi has been conducting 150-200 X-rays daily at the centre. Even as 5-10% of X-rays highlight abnormalities on average every day, not all of these patients test positive for TB. 'The X-rays highlight if there is fluid in the lungs, signs of pneumonia, old or new pneumonia and cavities in the lungs. If these abnormalities are found, we send the patient for further tests,' said Dr Umesh. With the X-ray machines, screening takes just 5-10 minutes, and the visitors can get details added to the system, which is convenient for many. One doctor, one technician and one patient mobiliser and a volunteer for registration of people have been deployed at each camp. Meanwhile, more women than men are visiting the camp at Indira Kalyan Vihar, according to the team. 'This may be because most of the women are at home, and the men of the house go to work. Which is why we are taking this till 4 pm to target the men as well,' said Himansh Parewa, junior field officer who has been mobilising people from the jhuggi cluster. 'We mobilise the community with the help of ANM and ASHA workers and TB health workers from the Dot centres,' he added. However, this does not mean more women are testing positive. 'Diabetics, malnourished smokers, those with a family history of TB have the highest prevalence, along with those who are living in poorly ventilated areas, which makes slum areas more at risk,' explained Dr Umesh. A majority of men in the area, according to Himansh, are factory workers who have to leave for work early morning, due to which it remains a challenge to screen them.
