Hi! we are the group infectious diseases and vaccinations 2. We are two slovkian students, two danish students and two Dutch students that are creating a website about tuberculosis, which is an infectious diseases which has killed and is still killing a lot of people. A total of 1.5 million people died from TB in 2014. And tuberculosis doesn't only apply to humans, animals can get it too. Scientists even have a theory that is was seals that initially carried tuberculosis across the Atlantic.

This website is made by the Dutch student, Loebna Sabbah

                                        some background information about the topic:

Infectious diseases all have their own specific symptoms but they have a couple general symptoms in common which are having a fever, suffering from diarrhoea and fatigue. Each disease differs in their cause, diagnosis, symptoms and treatment.
Infectious diseases can be caused by a different microbacteria such as bacteria; which are one celled organisms, viruses; which are even smaller than bacteria, fungi; which can infect your skin, lungs and nervous system and lastly parasites; which can be transmitted to humans by animals such as mosquitos.

In general infectious diseases can be transmitted from a person to another, from an animal to a person and from a mother to her unborn child.

 Scientists try to develop vaccinations for the different infectious diseases. When a person gets infected with a disease the body is dependent on its immune system. The immune system should do its work and fight of the damaging organisms. When an organism invades the body the white blood cells start producing antibodies, which are proteins that locate the infectious agent and then make a counter offensive. A life threatening infection is caused when the germs show symptoms faster than the production of the antibodies and it will hard for the antibodies to still be helpful. However after the disease is fought of the antibodies will not leave the body, they will stay and watch out for the next invader. If it is the same invader it can be fought off immediately if it is a slightly different invader the antibody will have to make a new variant. The more antibodies are present the higher the chance is that the invader only needs a slightly different antibody which will cause its production to be quicker.

 Vaccinations are made of the weakened version of the microbacteria causing the disease that is being fought. Sometimes the vaccine is made of the dead version of the organism causing the bacteria. In this  case the organism is killed in such a way that it helps protect or even become immune to the living form of the organism. So to explain it easily a vaccine makes the body think it is infected causing the body to make a protection system in case of a real infection.
