HIV, or Human Immunodeficiency Virus, is a virus that attacks the immune system, specifically targeting CD4 cells, also known as T cells, which play a crucial role in helping the body fight off infections. HIV can lead to acquired immunodeficiency syndrome (AIDS), a condition characterized by a severely weakened immune system, making individuals more susceptible to opportunistic infections and certain cancers. Understanding HIV is essential for both prevention and management. Here’s an in-depth look at HIV, its transmission, symptoms, diagnosis, treatment, and prevention measures: Transmission: HIV is primarily transmitted through certain bodily fluids, including blood, semen, vaginal fluids, and breast milk. The most common modes of transmission include unprotected sexual intercourse, sharing contaminated needles or syringes, and from mother to child during pregnancy, childbirth, or breastfeeding. HIV cannot be transmitted through casual contact such as hugging, kissing, or sharing utensils. Symptoms: In the early stages of HIV infection, individuals may experience flu-like symptoms, including fever, fatigue, sore throat, swollen glands, and rash. However, many people with HIV do not experience any symptoms for years. Without treatment, HIV can progress to AIDS, characterized by severe immune suppression and the development of opportunistic infections and cancers. Diagnosis: HIV can be diagnosed through blood tests that detect antibodies produced by the immune system in response to the virus. Additionally, tests that detect viral RNA or antigens can provide early detection of HIV infection before antibodies are produced. It’s essential for individuals at risk of HIV to undergo regular testing, as early diagnosis allows for prompt initiation of treatment and reduces the risk of transmitting the virus to others. Treatment: Antiretroviral therapy (ART) is the cornerstone of HIV treatment. ART involves a combination of medications that suppress the replication of the virus, reduce the viral load in the blood, and restore immune function. With effective treatment, people living with HIV can lead long and healthy lives. It’s crucial to adhere to the prescribed treatment regimen consistently to achieve optimal outcomes and prevent the development of drug resistance. Prevention: Prevention strategies are key to reducing the spread of HIV. These include practicing safer sex by using condoms consistently and correctly, avoiding sharing needles or syringes, and ensuring access to HIV testing and treatment services. Pre-exposure prophylaxis (PrEP), a daily medication regimen for individuals at high risk of HIV, can significantly reduce the risk of acquiring the virus. Additionally, efforts to promote education, raise awareness, and reduce stigma surrounding HIV/AIDS are essential in combating the epidemic.

Dr. Saurabh Pandey, Consultant Physician & Infectious Diseases Specialist, addresses the growing concern about Zika virus in Pune. With recent reports of two cases in the city, many people seek reliable information. Dr. Chaudhari emphasizes that Zika is not a new virus; it was first identified in Uganda in 1947. However, its global impact became significant after outbreaks in the Americas around 2015. The virus, primarily spread by Aedes mosquitoes, can also be transmitted from mother to fetus and through sexual contact, raising concerns due to its potential to cause birth defects and miscarriages. Despite these risks, Dr. Chaudhari reassures that most Zika infections are asymptomatic or very mild. He advocates for preventive measures against mosquito bites and stresses the importance of staying informed with accurate information to avoid unnecessary panic.

Introduction to ChikungunyaDr. begins by addressing common misconceptions about Chikungunya, often confused with chicken-related illnesses. He clarifies that Chikungunya is a viral infection transmitted by mosquitoes, particularly the Aedes mosquito, and has no connection with chickens or poultry. Origins and MeaningThe first case of Chikungunya was identified in Tanzania in the 1950s. The name originates from the Swahili language, meaning “to become contorted,” reflecting the severe joint pain and deformities associated with the disease. Global and Local ImpactChikungunya has caused outbreaks in various countries, including many in Asia and Africa. In India, since 2006, there have been numerous outbreaks across different states. As of now, 34 states and union territories in India are considered endemic for Chikungunya. TransmissionChikungunya spreads through the bite of an infected Aedes mosquito. This mosquito is also responsible for spreading dengue and Zika virus. The virus resides in the human body, and when a mosquito bites an infected person and then bites another individual, the virus is transmitted. Mosquito Characteristics and Environmental FactorsThe Aedes mosquito thrives in conditions prevalent during the monsoon season, such as moderate temperatures, high humidity, and stagnant water. Outbreaks are common during and after the monsoon period. The mosquito has a limited flight range, leading to clustered cases within specific localities. Symptoms and Phases of Chikungunya Dr. Chaudhari explains that Chikungunya symptoms typically develop within 5 to 7 days after a mosquito bite. The disease has three phases:   Acute Phase (up to 3 weeks): Sudden onset of high fever, severe joint pain, and a characteristic rash. Joint pain is intense, affecting small joints and causing significant discomfort. Subacute Phase (3 weeks to 3 months): Predominantly joint-related symptoms with pain, stiffness, and swelling. Chronic Phase (beyond 3 months): Persistent joint pain and stiffness, resembling rheumatoid arthritis. Differentiating Chikungunya from DengueDr. Chaudhari highlights the importance of distinguishing Chikungunya from dengue, as both are transmitted by the same mosquito. Key differences include the duration of fever, the onset of rash, and the presence of severe joint pain in Chikungunya. Systemic complications like a drop in platelet count and other severe symptoms are more common in dengue. High-Risk GroupsCertain populations are more likely to experience severe symptoms, including individuals over 45, females, those with chronic conditions like hypertension, hypothyroidism, COPD, and pregnant women. DiagnosisDiagnosing Chikungunya involves considering the clinical symptoms and recent travel history to endemic areas. Blood tests may not always be conclusive due to the lack of significant systemic abnormalities in Chikungunya.

Introduction to High-Risk Groups: The video addresses the differences in the presentation and complications of chikungunya in high-risk groups such as pregnant women, newborns, pediatric patients, and adults with medical conditions. Pregnant Women: Chikungunya infection during the first and second trimesters of pregnancy does not significantly affect the fetus. However, if the infection occurs close to delivery, there is a 40-50% chance of transmission to the newborn. Newborns: Newborns infected with chikungunya from their mothers typically exhibit symptoms such as fever and rash. However, joint pain is milder than in adults. They are at higher risk for complications like meningitis, skin infections, and bacterial sepsis due to weaker immunity. Pediatric Age Group: Children from several months to a few years old show similar symptoms to adults but are more likely to experience diarrhea and various types of rashes. They also face higher risks of systemic complications such as meningitis. Mortality and Morbidity: Mortality due to chikungunya in pregnant women, newborns, and pediatric patients is relatively low, but morbidity remains high, indicating significant health challenges without necessarily increasing the death rate. Adults with Comorbidities: High-risk adults, including those with diabetes, hypertension, heart disease, COPD, hypothyroidism, or co-infections like dengue or HIV, may experience more severe and prolonged joint pain. Impact on Comorbid Conditions: For diabetic patients, chikungunya can cause severe disruptions in blood sugar control. Hypertensive patients might experience lower blood pressure during the acute phase, necessitating adjustments in their medication. Systemic Complications in Adults: High-risk adults have a greater chance of systemic complications such as meningitis, lung issues, and acute liver or kidney involvement. However, these complications are less severe compared to those caused by dengue. Low Mortality, High Morbidity: The video emphasizes that while mortality from chikungunya is very low, morbidity can be extremely high, leading to significant health impacts and prolonged recovery periods. Upcoming Treatment Discussion: The video concludes by promising a follow-up video discussing treatment modalities aimed at reducing morbidity and alleviating pain related to chikungunya.

Phases of Chikungunya: Treatment is divided into acute, subacute, and chronic phases, each with specific management strategies. Acute Phase Treatment: Focuses on symptom relief with antipyretics (like paracetamol) and analgesics (e.g., tramadol, NSAIDs) as no antivirals or antibiotics are effective. Rest and Hydration: Emphasized the importance of adequate rest and hydration during the acute phase. Cold compresses can help alleviate joint pain. Avoiding Steroids Early: Steroids should not be used in the initial weeks as they can prolong viremia and lead to long-term complications. Subacute and Chronic Phase: Treatment depends on the severity of joint pain, which can be assessed using parameters like the number of joints involved and pain intensity on a visual analog scale. Stepwise Medication Approach: Mild pain can be managed with paracetamol, moderate pain with NSAIDs, and severe or persistent pain may require short-term steroids. Steroid Use: If steroids are necessary, they should be used in low doses and for short periods, not exceeding one month to avoid side effects like gastritis, peptic ulcers, increased blood sugar, and osteoporosis. DMARDs for Chronic Pain: If pain persists despite steroids, Disease-Modifying Antirheumatic Drugs (DMARDs) like hydroxychloroquine are recommended, with other DMARDs considered only after 8-12 weeks if necessary. Non-Pharmacological Methods: Ice fermentation and cold compresses during acute phases; physical activity, stretching exercises, and physiotherapy in subacute and chronic phases to maintain joint mobility and muscle strength. Overall Approach: Encourages a balanced approach combining pharmacological and non-pharmacological treatments, avoiding over-reliance on drugs with potential side effects, and promoting physical activity and physiotherapy.
