HIV is one of the most common sexually transmitted infections. It affects a significant part of the world’s population and is among the major health concerns. When left untreated for a longer period, it may lead to AIDS (acquired immunodeficiency syndrome), which is the most advanced stage. This infection spreads when a healthy person comes into direct contact with the bodily fluids (blood, semen, pre-seminal fluid, rectal fluids, vaginal fluids, and breast milk) of an infected person. Apart from this, it can also be transmitted from an infected mother to her child during pregnancy, childbirth, or breastfeeding. Early detection is the best way to control HIV infection and prevent its progression to AIDS. Booking an HIV test in a timely manner can help manage the symptoms in the initial stages.  What is an HIV test? It is a blood test that detects the presence of HIV (human immunodeficiency virus) in an individual’s blood. The human immunodeficiency virus attacks the cells of a...

HIV awareness is not a once-a-year conversation. World AIDS Day, observed every year on 1st of December, is a reminder that stigma, delayed testing, and misinformation can still stand between communities and timely care. So, strengthening awareness matters, as early detection and consistent treatment can protect health and reduce transmission. Understanding HIV and AIDS in 2026  HIV (human immunodeficiency virus) affects the immune system by damaging key cells involved in fighting infections. If left untreated for a long period, the immune system can become severely weakened, and the infection may progress to AIDS (the most advanced stage of HIV). Although progression is not immediate, it typically occurs over years without proper diagnosis and treatment. Now, despite medical progress, each passing day, hesitation around testing remains common due to fear and bias. UNAIDS estimates that 40.8 million people were living with HIV in 2024, and that millions still did not know their HIV...

Fever is one of the most common symptoms of infectious diseases, which can often present with similar signs. Accurate diagnosis is crucial to identify the underlying cause and ensure timely treatment. Two common diagnostic approaches include the Widal test and the Fever panel test. These tests help identify the root cause of fever and guide doctors in initiating appropriate treatment. While the Widal test is used to detect typhoid fever, the fever panel test is a broader screening method that checks for multiple infections such as dengue, malaria, and urinary tract infections. Understanding the purpose, importance, and procedure of each test helps clarify their role in modern clinical practice. Widal Test Purpose ● Detects antibodies (O and H antigens) against Salmonella typhi and Salmonella paratyphi. ● Assists in diagnosing typhoid and paratyphoid fever. ● Used as a supportive tool when typhoid is suspected. Importance ● Useful in identifying the body's immune response a...

Hepatitis B is a common, serious liver infection caused by the hepatitis B virus. It can be transmitted through direct contact with infected blood or certain bodily fluids. The most common method of transmission is from infected pregnant women, who can transmit hepatitis B to the baby during childbirth. It is also called a silent epidemic, as most people do not show symptoms when they are newly infected and can unknowingly spread it to other people. However, hepatitis B is curable, and there are some blood tests which can diagnose the infection. HBsAg The HBsAg test detects the HBsAg, a protein on the surface of the HBV during acute or chronic HBV infection. A positive HBsAg result indicates that a person has contracted the hepatitis B infection. After this, further testing is needed to diagnose whether the infection is acute or chronic. Anti-HBs This blood test measures whether a person has immunity against the hepatitis B virus. The presence of anti-HBs is an indication of recovery ...

Typhoid fever is a bacterial infection caused by the bacterium Salmonella Typhi. It affects millions of people worldwide every year. This is why awareness and early detection of this bacterial infection are important. Here is all you need to know about typhoid fever: How Does Typhoid Fever Spread? Typhoid is a bacterial infection that spreads through contaminated food and water (with Salmonella Typhi). It is a common infection in many parts of the Indian subcontinent. When the bacteria pass through the intestinal walls, they reach the blood in a short time. The infection can spread to various organs, such as the liver, gallbladder, and bone marrow. Common Symptoms of Typhoid Fever Fever Body ache Weakness Abdominal pain Loss of appetite Cough Slow pulse rate Important Tests for Typhoid Fever Widal Test A Widal test is one of the most common typhoid fever tests. It confirms the presence/absence of serum agglutinins or antibodies (O and H) in the blood. If a Widal test report is positiv...

  Rheumatoid Arthritis (RA) is a chronic condition that causes inflammation and pain in the joints. It is an autoimmune disease that affects the lining of the joints and damages the tissues covering the ends of the bones in a joint, causing the joints to bend or deform. Common symptoms of RA may include: Joint pain and stiffness on movement Hard nodules under the skin, near the joints Fatigue and frequent fever Loss of appetite Tenderness, swelling or warmth in the affected joint Joint deformity and reduced motion Most of the time, symptoms affect the same joint on both sides of the body. The inflammation can often also spread to other parts of the body. While there is no cure for rheumatoid arthritis, timely diagnosis and care can be essential to prevent the condition from getting worse.  A CRP test and a CCP antibody test are cost-effective tests that can help confirm an RA diagnosis . Role of CRP Test in Diagnosing Rheumatoid ...
