Q. Why do some flu viruses cause more severe infections?
Doctor Answer is medically reviewed by SecondMedic medical review team.
The severity of a flu virus’s infection largely depends upon the characteristics (virulence factors) of the virus itself, as well as the individual person infected. Viruses that possess more virulence factors tend to cause more severe infections than those with fewer or less virulent properties. For example, certain types of flu viruses contain an extra gene segment which codes for proteins that help increase the ability of the virus to spread within cells, leading to increased severity in symptoms. Additionally, other types may include extra surface proteins called hemagglutinins and neuraminidases that can better bind to cells lining respiratory tracts, further exacerbating symptoms.
Individual risk factors can also contribute to a severe influenza-like illness; these include having weakened immune systems due to underlying medical conditions such as HIV/AIDS or cancer treatments like chemotherapy or radiation, age (children under 5 and adults over 65 are at greater risk), obesity and smoking status all play a role in determining how severely you could experience your infection if infected with an influenza virus. In summary, there is no one answer as both viral properties as well as individual differences can lead to varying levels of severity when it comes to influenza infections!
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?

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.
