Viral Infections: HIV and Tobacco Mosaic Virus
HIV is a serious virus that initially causes flu-like symptoms but can develop into AIDS if left untreated. You can prevent HIV by using condoms during sexual contact and never sharing needles. The virus spreads through sexual contact and sharing contaminated needles, making safe practices absolutely essential.
Antiretroviral drugs can help manage HIV, but prevention remains the best strategy. These medications help people with HIV live healthier lives by controlling the virus in their body.
Tobacco mosaic virus affects plants, creating a distinctive mosaic pattern on leaves that reduces photosynthesis and slows plant growth. Farmers prevent this by using crop rotation, virus-free seeds, and controlling insects that spread the disease.
Key Insight: Both human and plant viruses can be prevented through smart practices - safe behaviour for humans, and proper farming techniques for plants.
