Q. How is HIV transmitted?
Doctor Answer is medically reviewed by SecondMedic medical review team.
HIV is primarily transmitted through specific body fluids that contain high concentrations of the virus. The main modes of HIV transmission include:
1. Unprotected Sexual Contact:
- HIV can be transmitted through unprotected sexual intercourse (vaginal, anal, or oral) with an infected person, particularly if there are open sores, cuts, or mucous membranes present.
2. Sharing of Needles:
- Sharing needles or syringes with an infected person, such as in the context of injecting drugs, can transmit HIV.
3. Mother-to-Child Transmission:
- HIV can be transmitted from an HIV-positive mother to her child during childbirth, delivery, or breastfeeding.
4. Blood Transfusions and Organ Transplants:
- In the past, HIV transmission occurred through contaminated blood or blood products. However, blood screening measures have significantly reduced this risk. Organ transplants from infected donors could also transmit HIV.
5. Occupational Exposure:
- Healthcare workers may be at risk of HIV transmission through accidental needle sticks or contact with infected blood.
6. Contaminated Instruments:
- The use of contaminated instruments for medical or cosmetic procedures can pose a risk of HIV transmission.
7. Pre-existing STIs:
- Sexually transmitted infections (STIs) that cause open sores or lesions can increase the risk of HIV transmission during sexual contact.
It's important to note that HIV is not transmitted through casual contact, such as hugging, kissing, shaking hands, sharing utensils, or through the air like the flu virus. Additionally, consistent and correct use of condoms and the availability of pre-exposure prophylaxis (PrEP) can significantly reduce the risk of sexual transmission.
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
