World Aids Day
The global challenge of HIV/AIDS remains one of the most pressing public health issues today. According to the latest data from UNAIDS, around 38.4 million people worldwide are living with HIV/AIDS, underlining the need for not only medical intervention but also comprehensive awareness, education, and social change. Despite the significant strides made in treatment and prevention, the confusion surrounding the relationship between HIV and AIDS still persists.
Young people have become influential advocates in the fight against HIV/AIDS. Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities. These young activists utilize digital platforms and peer-to-peer education to dispel myths, promote safe practices, and foster supportive environments for those affected by HIV/AIDS.
Dr Gowri Kulkarni, an expert in Internal Medicine, explains that while the terms HIV and AIDS are often used interchangeably, they are distinctly different. "HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, whereas AIDS (Acquired Immunodeficiency Syndrome) is a condition that occurs when HIV severely damages the immune system," she clarifies. To understand the implications of these differences, it's important to explore the fundamental distinctions between the two.
HIV is the virus responsible for attacking the body’s immune system, specifically targeting CD4 cells, which are crucial for the body’s defense against infections. As HIV progresses, it destroys these cells, weakening the immune system over time. If left untreated, this continuous damage can lead to AIDS.
AIDS, on the other hand, is a syndrome, not a virus. Dr Kulkarni further elaborates that AIDS is a collection of symptoms and illnesses that emerge when the immune system is severely compromised due to prolonged HIV infection. It represents the most advanced stage of HIV, and is characterized by very low CD4 counts or the onset of opportunistic infections like tuberculosis, pneumonia, or certain cancers.
A key distinction to remember is that not everyone with HIV will progress to AIDS. Thanks to advancements in medicine, particularly antiretroviral therapy (ART), individuals living with HIV can manage the virus and maintain a healthy immune system for many years, or even decades, without ever developing AIDS. ART works by suppressing the virus to undetectable levels, effectively preventing the damage HIV would otherwise cause to the immune system.
Without treatment, however, HIV progresses through three stages:
- Acute HIV Infection: This stage occurs shortly after transmission and may include symptoms like fever, fatigue, and swollen lymph nodes.
- Chronic HIV Infection: Often asymptomatic or mildly symptomatic, the virus continues to damage the immune system but at a slower rate.
- AIDS: This is the final stage, marked by severe immune damage and the presence of infections that take advantage of the compromised immune defenses.
Another key distinction between HIV and AIDS is the way in which they are transmitted. HIV is highly contagious and can be transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is primarily spread through unprotected sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding.
AIDS, however, is not transmissible. It is not a disease that can be passed from one person to another. Rather, AIDS is the result of untreated, advanced HIV infection and is a direct consequence of the virus’s damage to the immune system.
HIV and AIDS are diagnosed through different methods. HIV is diagnosed through blood tests or oral swabs that detect the presence of the virus or antibodies produced by the immune system in response to the virus. Early detection of HIV is crucial, as it allows for timely intervention and treatment, which can prevent the virus from progressing to AIDS.
AIDS, on the other hand, is diagnosed using more specific criteria. Dr Kulkarni notes that the diagnosis of AIDS is made when the individual’s CD4 cell count falls below 200 cells/mm³, or when opportunistic infections or certain cancers (such as Kaposi's sarcoma or lymphoma) are detected. Diagnosing AIDS involves a more thorough assessment of the individual’s immune function and overall health, as opposed to just the detection of HIV.
The treatment goals for HIV and AIDS differ significantly, although both involve antiretroviral therapy (ART). For HIV, the primary treatment goal is to suppress the virus to undetectable levels, thus maintaining a strong immune system and preventing further transmission of the virus. People living with HIV can often live long, healthy lives if they adhere to ART.
For individuals diagnosed with AIDS, the treatment plan becomes more complex. While ART remains an essential part of managing the virus, treatment for AIDS also focuses on addressing the opportunistic infections and secondary health complications associated with severe immune suppression. The goal of treatment for AIDS is not only to manage the HIV virus but also to improve the quality of life and extend survival by treating these secondary health issues.
While the medical community has made great strides in managing HIV, the battle to curb its transmission is also a social and cultural issue. Dr Daman Ahuja, a public health expert, highlights that HIV/AIDS awareness and education are vital to reducing transmission rates and supporting those affected by the virus. "Young people, especially, have become key advocates in the fight against HIV/AIDS," says Dr Ahuja. "Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities."
Additionally, grassroots activism plays a significant role in raising awareness and addressing stigma. As the World Health Organization reports, community-based interventions have been proven to increase HIV testing rates and improve treatment adherence, which are crucial in the fight against the pandemic.
The ultimate goal of organizations like UNAIDS is to eliminate the HIV/AIDS pandemic by 2030. Achieving this requires global collaboration, from medical treatment advancements to public health strategies, education, and advocacy. Dr Kulkarni’s insight underscores the importance of early detection, treatment adherence, and community support in the fight against HIV/AIDS.

Many women experience bloating, acidity, stomach discomfort, or constipation from time to time. These symptoms are usually linked to diet, stress, or minor digestive issues. However, these are often overlooked.
On World Ovarian Cancer Day, doctors are urging women to pay closer attention to such recurring symptoms and seek timely medical advice.
World Ovarian Cancer Day is observed every year on May 8 to raise awareness about ovarian cancer and promote early detection. This year’s theme is “No Woman Left Behind.”
According to global estimates, nearly 250,000 women are diagnosed with ovarian cancer each year, and about 140,000 die from the disease.
Ovarian cancer is one of the deadliest gynecological cancers and is often referred to as the “silent killer” because its early symptoms are vague and easily mistaken for common digestive or urinary issues.
It develops when abnormal cells in the ovaries grow uncontrollably and may spread to other parts of the body. Survival rates are significantly higher when detected early—around 93 per cent of women diagnosed at stage one survive at least five years, compared to just 13 per cent at stage four, according to the American Cancer Society.
Unfortunately, many cases are diagnosed at advanced stages, when treatment options are limited, and outcomes are poorer.
“Ovarian cancer is commonly called a ‘silent disease’ because its early signs are vague and often resemble routine gastric issues,” Dr. Tejinder Kataria, Chairperson – Radiation Oncology, Medanta Hospital, Gurugram, told HealthandMe.
Common symptoms include:

One should not ignore these symptoms if they persist for more than two to three weeks.
“Many women delay seeking medical attention because these symptoms feel too common to be serious. Early evaluation through clinical examination, imaging, and blood tests can help detect the disease earlier,” Dr Kaur noted.
“The growing tumor can press on nearby organs such as the intestines or bladder, leading to digestive changes and abdominal discomfort,” she explained.
The experts also highlighted several risk factors that are often overlooked, including:
Being aware of subtle and persistent symptoms can significantly improve outcomes. Ovarian cancer survival rates are much higher when diagnosed early, making timely medical consultation crucial.

Thalassemia, particularly thalassemia major and thalassemia intermediate, can affect fertility and pregnancy due to iron overload caused by repeated blood transfusions. In these patients, excess iron gets deposited in various endocrine and vital organs, leading to hormonal disturbances and fertility-related complications.
Patients with thalassemia major usually require regular blood transfusions for survival, sometimes every one to three months. Thalassemia intermediate patients may require fewer transfusions, but they too remain at risk of iron overload. Over time, excess iron can accumulate in organs such as the pituitary gland, thyroid, ovaries, kidneys, liver, and suprarenal glands. This iron deposition can impair hormonal function and contribute to infertility. Experts note that many patients with thalassemia major may face fertility issues because of this reason.
Dr. Sunil Bichile, Hematologist, Saifee Hospital, Mumbai, said, "Although thalassemia management has improved significantly over the years, pregnancy in such patients is still considered high-risk. " Even when iron levels are properly managed, risks to both the mother and fetus may still exist. However, these complications are mainly seen in thalassemia major and thalassemia intermediate patients. Individuals with thalassemia minor generally do not face these fertility or pregnancy-related issues and can have normal pregnancies."
"Doctors also emphasise the importance of carrier screening and prenatal diagnosis. If both partners are thalassemia carriers, prenatal testing around 12 weeks of pregnancy can help determine whether the fetus has thalassemia major. Early diagnosis allows families and doctors to make informed medical decisions and helps reduce severe thalassemia cases," Dr Bichile added.
Women with thalassemia are now increasingly able to experience healthy pregnancies due to advances in medical care. However, one of the most important concerns during pregnancy in thalassemia patients is iron overload—a condition caused by repeated blood transfusions over many years. Excess iron gets deposited in vital organs such as the heart, liver, and endocrine glands, potentially leading to serious complications if not managed properly before conception and during pregnancy.
"Iron overload can significantly increase pregnancy-related risks. When excess iron affects the heart, it may lead to cardiac complications such as arrhythmias or heart failure, which can worsen during pregnancy because of the increased workload on the cardiovascular system. Iron deposition in endocrine glands may also cause hormonal imbalances, affecting fertility and increasing the risk of gestational diabetes, thyroid disorders, or difficulties in maintaining a healthy pregnancy," Dr Liza Bulsara, Pediatric Hematologist and Oncologist, Ruby Hall Clinic, Pune, explained.
Women with poorly controlled iron overload may face a higher chance of miscarriage, fetal growth restriction, preterm delivery, or complications during childbirth. In some cases, liver dysfunction caused by iron accumulation can further complicate pregnancy management. Additionally, anaemia associated with thalassemia itself may increase fatigue and reduce oxygen supply to both mother and baby if not carefully monitored.
Dr Bulsara emphasised that pre-pregnancy counselling is essential for women with thalassemia. A detailed assessment of iron levels through serum ferritin tests and MRI evaluation of the heart and liver helps doctors determine whether the body is prepared for pregnancy. Proper iron chelation therapy before conception plays a crucial role in reducing excess iron stores and improving maternal outcomes. During pregnancy, transfusion schedules, haemoglobin levels, cardiac health, and fetal growth require close multidisciplinary monitoring.

Thalassemia is a hereditary illness that hampers the production of haemoglobin, the component of red blood cells that carries oxygen throughout the body. If the production of haemoglobin is faulty or reduced, a shortage of healthy red blood cells occurs, resulting in anaemia and reduced oxygen supply to the organs.
"Thalassemia is, in fact, a collection of conditions ranging from a simple carrier state with no symptoms to a very severe disease requiring lifelong treatment. Mostly, thalassemias are classified into alpha and beta types, depending on which chain of the haemoglobin molecule is defective," said Dr Sneha Shinde, Consultant – Paediatric Haemato-Oncology, P.D. Hinduja Hospital and MRC Centre, Khar.
As per National Health Mission figures, nearly 42 million people in India are beta thalassemia carriers, and about 10,000 to 15,000 infants with thalassemia major are born every year.
This disease is inherited from parents through genes. If both parents are carriers, their child may develop a severe type of the disease.
Symptoms largely depend on the severity of the illness and can include tiredness, weakness, pale complexion, difficulty breathing, stunted growth, enlarged spleen or liver, and changes in facial bones. Most severe cases become apparent during infancy or the toddler years.
Dr Shashikant Apte, Director – Haematology, Sahyadri Super Speciality Hospital, Nagar Road, said, "Symptoms can vary from person to person. Some individuals may simply feel low on energy, while others may notice pale skin, shortness of breath, or delayed growth in children. Because these signs are common, they are often ignored or mistaken for general weakness. The majority of children with thalassemia major require blood transfusions every month for the rest of their lives to maintain haemoglobin levels above 9 gm%."
Dr Shinde explained that diagnosis comprises blood tests such as Complete Blood Count (CBC), HPLC haemoglobin electrophoresis, and genetic analyses. Mild cases may hardly need treatment, but more serious or transfusion-dependent thalassemia cases usually require regular blood transfusions along with iron chelation therapy to avoid iron overload. Besides bone marrow transplantation and newly discovered gene therapies, treatment advancements are gradually leading to better patient survival and improved quality of life.
Dr Apte said, "The positive aspect is that thalassemia can be detected with a simple blood test. Early diagnosis helps in managing the condition more effectively. Therefore, it is advisable to undergo screening for thalassemia before marriage or before planning a pregnancy, so the level of risk can be assessed. If both parents are thalassemia minor carriers, DNA testing should be conducted to identify the genetic defect and enable prenatal diagnosis during the 12th week of pregnancy. If the child is diagnosed with thalassemia major, pregnancy termination may be considered between the 14th and 16th week, based on medical advice and individual circumstances."
Of equal significance is the fact that thalassemia can be prevented through premarital or pre-pregnancy carrier detection and genetic counselling. Early awareness, proper diagnosis, and making informed reproductive choices are the key factors in reducing the burden of this lifelong blood disorder.
Dr Shashikant Apte, Director – Haematology, Sahyadri Super Speciality Hospital, Nagar Road, spoke about the incidence of constant fatigue and answered FAQs about thalassemia major, while sharing tips on living with it.
Being tired every day is typically attributed to a busy lifestyle; however, it can also have underlying medical reasons. Thalassemia is one of the conditions a person is born with that can cause fatigue due to a lack of oxygen. Thalassemia is a disorder in which the proper formation of haemoglobin — the protein in blood responsible for carrying oxygen — does not occur correctly. When haemoglobin is not formed properly, the body does not receive enough oxygen, leading to frequent tiredness and weakness.
Thalassemia major is an inherited disorder, meaning it is passed down from both parents to their child. Some individuals may simply be carriers without displaying any symptoms. During each pregnancy, there is a 25 per cent chance of passing the abnormal gene to the foetus, which may result in severe complications related to thalassemia major or other conditions associated with a lack of oxygen. Therefore, it is critical to know your family’s medical history and thalassemia minor (carrier) status.
Dr Apte went on to say that although thalassemia is a chronic condition, there are highly effective ways to manage it with proper medical guidance. Regular medical check-ups and prompt treatment can help individuals maintain good overall health and lead a normal life.
Understanding thalassemia is the first step towards prevention and better management. Awareness allows individuals and families to make informed decisions and avoid complications before the condition becomes severe.
