After a person recovers from an infection why are they usually immune if they are exposed to the pathogen again?
After recovering from an infection, a person's immune system retains memory cells that have been specifically trained to recognize the pathogen. These memory B and T cells can quickly respond to future exposures by producing antibodies and activating immune responses, often preventing reinfection or significantly reducing the severity of illness. This adaptive immune response provides a form of immunity known as "adaptive immunity," which can last for months to years, depending on the pathogen.

What is active acquired immunity?
Active acquired immunity occurs when you get an infection by a pathogen (bacteria, virus) and your body responds and removes the pathogen and also your body makes "memory" cells. These cell remember this pathogen and when it enters your body again you remove it immediately. You are now immune to it. You usually don't notice this.

Why do you get sick the first time when you are infected with a pathogen?
When you are infected with a pathogen for the first time, your immune system has not been previously exposed to it and needs time to recognize and develop a specific response to fight off the invader. This initial lag in immune response allows the pathogen to replicate and cause symptoms of illness before the immune system can mount an effective defense.

What is leucocyte infection?
Leukocyte infection typically refers to a situation when white blood cells (leukocytes) are infected by a pathogen such as a virus or bacteria. This can affect the immune system's ability to fight off infections and can lead to various health complications. Medical attention is usually necessary to address leukocyte infections.

If you broke your toe and left it untreated could it cause infection throughout your entire body like having intense cranial pressure that feels like a sinus infection with no infection present?
Broken toes are usually very minor injuries and there are usually very few complications. If you break your toe and leave it untreated, it usually cannot cause infection throughout your entire body. However, open or compound toe fractures have the potential to cause infection because there is a break in the skin and the bone is exposed. Open toe fractures must be treated to prevent infection and can only be treated by a physician using antibiotics and surgery. If you have an open toe fracture or are worried about the possibility of infection, you need to see a physician as soon as possible.
What is the correlation with HIV and CD4 cells?
After infection, the CD4 count measured in blood generally reduces in the first month or two and then recovers, but not to the pre-infection level. Then, usually over many years the CD4 count reduces until HIV advances to cause symptoms. Anti-retroviral treatment stops the decline in CD4 cells which then usually recover and get stronger again. With HIV there is a lot of individual variability in how fast this takes. Some people need treatment soon after infection and other can still have a strong CD4 count after 15 years without treatment.
Is Nosocomial infection a food infection?
It could be but usually is not. Nosocomial simply means that the infection [caused by any type of pathogen, including food-borne germs] was acquired in a health care setting, such as a hospital, lab, surgical center, doctor's office or clinic, etc. It could be viral, bacterial, fungal, parasitic or any type of infection as long as it was "caught" in a health care location. Food-borne infections are very rare in the closely controlled kitchens of hospitals, but not unheard of.
