Are allergies immune disorders?
Allergies are kind of like an immune disorder but not in the typical sense, rather people that have allergies just have extremely reactive immune systems. Basically what this means is that when you come into contact with an allergen (dust, pollen, animal fur and so on) your body reacts to this substance in order to protect itself. the body releases histamines to defend itself against the allergen. it is this histamines that often produce the symptoms associated with allergies, such as sneezing, watery eyes and sinus congestion.
What is inflammatory skin disease with erythematous papulovesicular lesions?
Contact dermatitis is an inflammatory skin condition characterized by red, itchy, and blistering papules or vesicles. It occurs when the skin comes into contact with an irritant or allergen, triggering an immune response that results in the skin becoming inflamed.
Can Conjunctivitis be cured?
Conjunctivitis caused by an allergic reaction should clear up once the allergen is removed. However, allergic conjunctivitis will likely recur if the individual again comes into contact with the particular allergen.

How can the human have H.I.V without aids?
Easy, if you know what the names mean.HIV is the name of a virus that attacks the immune system.We're always surrounded by viruses, and they're generally not a problem as long as the immune system is able to fight them off.AIDS stands for Acquired Immune Deficiency Syndrome.This is a clumsy way of saying that the immune system has gotten weaker, and is failing because of being under attack by the HIV virus.Today there are medicines that can help the immune system resist the damage from the HIV virus. We can't get rid of the virus completely, but we can keep it from beating the immune system.The result is a person can have the virus, but not have AIDS, as AIDS only comes when the immune system is weakened and beaten.

Can you catch the Swine Flu from a child who has had the Swine Flu mist?
The mist form of the H1N1/09 vaccine (or any intra-nasal flu vaccine) is made with "live" virus particles. They are weakened so that they can not make a person with an otherwise healthy immune system sick. If a person with HIV/AIDS or other immune system disorder, or who is on medicines that affect their immune system responses (chemotherapy for cancer, etc.), comes in contact with the live virus by being in close proximity to the child or adult immediately following their vaccination with the mist form of vaccine, then it is possible that they could be infected if one of the particles of weakened virus is shed by the one vaccinated. The person who has a compromised immune system would and have no defenses against the virus. It is recommended that anyone who lives with or cares for a person who has an immune system disorder get the injectible form of vaccine, which is made with totally "dead" virus particles and can not impact even a person with immune system problems.
