An infectious disease will die off eventually if it is not passed on to new hosts.
The concept of dominance applies only to genetic diseases. Chlamydia is an infectious disease, not a genetic disease. You can be a carrier of chlamydia; that is, you can be infected and capable of passing the infection without having symptoms.
The military needs healthy individuals to serve. Health issues will prevent one from passing the entry physical. And if you do not reveal the condition, you can be discharged when it is discovered.
No. Influenza is an infectious disease. A hereditary disease is one you are born with because one or both of your parents carry the gene responsible for passing the disease on to their children. For instance, if you visited a friend who had cystic fibrosis and 'flu, you could catch the 'flu from him, but not the hereditary disease of cystic fibrosis.
Krohn disease
Friedrich Loeffler discovered the cause of foot and mouth disease in 1897 as being a viral disease. He discovered this from passing infected FMD blood through a filter and the fluid that came out could still infect a healthy animal. As to who discovered the disease's existence we have no way of knowing, the US has been having outbreaks since the 1870s, and the disease has probably been around much longer than that.
you don't and it would not be healthy if you did.
Semmelweis noticed that the death rates in mothers during pregnancy was unusually high. He noticed that the doctors in his hospital were going straight from examining diseased dead bodies in the morgue to delivering babies, and thought that perhaps this meant that they were transferring disease from the corpses to the mothers. He suggested that all doctors thoroughly wash their hands between patients, and almost immediately the death rate fell. This was the first time that the idea of infectious disease (passing disease via a pathogenic medium, i.e. bacteria and viruses) was considered. before this, contracting diseases was put down to chance.
yes birds can give people a disease, eg:bird flu
highly unlikely
Saint Nicholas... who stressed the importance of drawing material goods for passing them onto the poor.
This could be caused by anything from infectious disease to results of a traumatic accident. More information would be necessary to hazard even a guess as to what sort of problem the horse has. A call to the veterinarian to discuss what is seen would be recommended in order to make a more educated decision as to whether or not it warrents a veterinary visit or not.
Testing is usually reserved for hospitalized cases since the treatment would be the same regardless of the exact type of the virus if you are not that ill. If you know you have been exposed to someone who was infectious with swine flu (H1N1/09), then as long as you are otherwise healthy, you should wait and watch to see if you begin to have any of the symptoms. Exposure does not guarantee transmission of the virus, but in case you are incubating it, you will want to use all precautions to avoid passing it along to others, you can be infectious to others before you even show signs. See related question below for information about the symptoms and prevention. Then, if you have or think you have the flu, see the related question below for information about what to do. If you have been exposed and you have an immunological disease or disorder, or other serious medical conditions, then seek advice from your primary health care professional.
