We call this type of immunity adaptive---> natural----> active immunity. Here how it works:
Adaptive immunity involves two classes of lymphocyte: B cells and T cells which work together in a coordinated system of adaptive immunity
B cells-antibody-mediated (humoral) immunity
T cells-cell-mediated (cellular) immunity
Adaptive immunity occurs in a series of stages
1. Recognition of antigen (flu virus)
2. Activation of lymphocytes
3. Effector phase (immune attack)
4. Decline of antigen causes lymphocyte death (homeostatic balance)
5. Memory cells remain for later response if needed
yes,you can get influenza by kissing,if Your immune system were weak against that virus
Flu viruses that people are not immune to.
You are not immune to Influenza. Even getting the yearly flu vaccine is no guarantee that a person won't get the flu. You can get the flu but it won't be as bad as it could be if you hadn't received the flu vaccine.
T cells are the components of the immune system that coordinate immune defenses and kill infected cells on contact.
When the body is infected with a pathogen, the immune system recognizes the foreign bodies and raises the temperature to try and kill of the pathogens. This causes a fever, which is an increase in body temperature above 98.6 degrees Fahrenheit.
Also. Allied the innate immune system, cells and proteins involved recognize structures shared by classes of microbes not present on the body's own cells and can also recognize molecules released by infected, damaged, or dead cells. The innate system can eliminate microbes on its own but more commonly cells of the innate immune system release chemokines to attract cells that are involved in the adaptive immune system to initiate an antigen or microbe specific immune response
antibiotic
You can't, the survivors you play as are immune to the disease the infected carry. So it is impossible.
The immune system identifies, remembers, attacks and destroys disease-causing invaders or infected cells.
Brain
Influenza (flu) can be from moderate to serious. So some influenza may cause some serious harm to your body. But others may already be in your immune system so you would react to it differently than others.
The Immune system is very weak
