IMMUNOLOGY

Detailed explanation-1: -The American Academy of Allergy Asthma & Immunology reports that signs of a possible immune deficiency in adults include: Having more than four ear infections in one year. Developing pneumonia twice during a one-year period. Suffering from chronic sinusitis or more than three episodes of bacterial sinusitis in a year.

Detailed explanation-2: -Some of this may have to do with a few infectious organisms, like flu viruses, thriving in colder temperatures, but there’s also evidence that exposure to cold temperatures suppresses the immune system, so the opportunities for infection increase.

Detailed explanation-3: -Immunocompromisation is a way to describe a weak immune system. When your immune system is weakened, your body can’t fight off viruses, bacteria, or fungi very well. This can lead to serious infections and can pose a major health risk. Many different types of immune system disorders can cause health problems.

Detailed explanation-4: -Also, infections like the flu virus, mono (mononucleosis), and measles can weaken the immune system for a brief time. Your immune system can also be weakened by smoking, alcohol, and poor nutrition.
