Why do you get sick the first time when you are infected with a pathogen?

Because specialized B cells make antibodies that are effective against that particular invader. Therefore, the first time you are infected, you usually get sick.

What is the time between a pathogen invasion and the first symptoms called?
It's called the Incubation Period.
What does harmless pathogen do?
A harmless pathogen can be injected into your body so that the bodies defence system will learn to recognise the antigens (harmful protein located on surface of pathogen) and to fight it easily the next time having remembered the antibodies it had to produce. and sorry if this is a little confusing.
What type of pathogen is HIV caused by?
"Pathogen" means something that causes sickness (path- = suffering, gen- = creation). "HIV" stands for "Human Immunodeficiency Virus," which is a virus which sometimes, in time, causes the disease AIDS ("Acquired Immune Deficiency Syndrome"). In other words, HIV is the pathogen, and being infected by HIV is the cause of the disease AIDS.The best ways to avoid being infected by HIV is never ever to share needles for drugs, and never ever to have penetrative sex without a condom. If you steer clear of those, as long as you live in part of the world where HIV isn't endemic, you are likely safe from HIV.There is no cure for HIV infection or AIDS, but there are very effective treatments.
Explain the principles of Immunization against communicable diseases?
a weaker/dead form of the pathogen is introduced to allow the body to produce the correct antibodies and make a memory-B cell that stimulates a faster immune response if the same pathogen is encountered a second time, preventing a full scale infection and making you "immune" to that pathogen
What is subtractive genomics?
Subtractive genomic strategy is developed by assuming that the novel targets identified in the pathogen should be essential for the pathogen that is it should be involved in the replication, survival and a important component of various metabolic pathways and mechanisms occurring in the pathogen while at the same time should be absent on the host that is human and should have no homologue in human, so that when a drug or a lead compound is designed considering the potential target it should only be against the mechanism and functionality of the pathogen not the host.
Will saliva make you sick?
In a way... The secretion of extra saliva signals that it's time to puke. no if the saliva is not infected

It's called the Incubation Period.
What is vector in plant pathology?
A vector is an organism that can carry pathogen(= disease causing organism) from infected plant to a health plant. Generally, a vector is an insect, a nematode, a fungi, or insect like organisms e.g. spider mites. To qualify as vector, the organism must have the ability to acquire the pathogen, must be able to retain the pathogen for some length of time and lastly it must be able to inject it into a suitable/susceptible plant. The relationships between the vector and pathogen can be described as simple if the pathogen does not circulate or replicate in the vector or complex if the pathogen replicates or circulate in the vector. In the latter case, the vector also acts as the host of the pathogen.
Are you usually sick after your first time?
always, and the second time as well
Can you get hiv from an infected person the fisrt time you have intercourse?
Yes. It doesn't matter whether you are a virgin or not; you can get AIDS from unprotected sex with an infected person the very first time. Use a condom EACH AND EVERY TIME.
What percentage of women first infected with toxoplasmosis pass it onto the fetal system?
One-third of women who are infected for the first time during pregnancy, the parasite infects the placenta and enters the fetal circulation.
When your infected with HIV what time frame is it that you were infected?
it depends

What does the worldwide epidemic look like?
All things start small. Epidemics are no different. The first infected individual will come into contact with a newly mutated pathogen, or possibly, a completely unknown pathogen. That individual becomes infected. The method of transmission is going to determine what happens next, but generally there are two varieties of pandemics. The first is going to be fast. The pathogen will probably be spread through the air, physical contact, or both. The disease spreads rapidly (depending on virulence) and it takes some time for the world organizations to get ahold of the situation. Depending on the lethaality of the pathogen, it's virulence, and whether or not it becomes a global pandemic mass hysteria will ensue, egged on by the 24 hour media cycle. People will scramble for medical supplies, food, water, ammunition, firearms, somewhat orderly at first, and then depending on the situation society, may begin to deteriorate in localized areas as organizations ability to respond to the situation become overwhelmed with the tasks at hand. Looting may become widespread as supplies dwindle. Curfues are put in place and governments begin to quarentine the areas where the infection is. The quarentines simply forces the infection to burn itself out. Effectivly infecting every possible host before either everyone is sick, or, only people with genetic immunity are still uninfected. Hollywood LOVES this one because it's scary and sells tickets. The second is much slower. A great example would be the HIV pandemic. It's quiet, people aren't violently ill until close to death and they can be infected for extremely long periods of time without visible symptoms. Obviously HIV can only be acquired by swapping bodily fluids, usually sexually or through intravenous drug use but if some new pathogen were able to spread quickly while simultaneously taking years to show visible effects? We might all be infected before we realized it.
