The answer is yes.
It takes 3-14 after infection with the barcteria to start showing clinical signs of the infection
This would be strangles, an infection caused by Streptococcus equi equi. The bacteria is highly contagious and can infect an entire stable within several days of the first animal becoming ill. The bacteria can infect the lymph nodes of the body (called bastard strangles and usually difficult to treat) or it can localized in the gutteral pouch (a diverticulum off the airway that sits in the throatlatch area). The disease is called strangles because the bacteria causes swelling of the gutteral pouches which can cut off the trachea and literally strangle the horse to death.
Strangles is a bacterial infection and is susceptible to certain antibiotics. However, antibiotic use at the wrong time may prolong recovery from the disease so should not be initiated without consulting a veterinarian first.
I am pretty sure that you are contagious for 24 hours after your first dose.
It depends on what virus it is. Some viruses, like the West Nile virus, aren't contagious. Other viruses are contagious.
to be clean
There does not appear to be a period of time that a cold is least contagious. Scientists believe that a person who has the common cold can be contagious for a few days before their symptoms begin right up until the time when their symptoms subside. This period of time could take up to two weeks. However, the period of time when a cold is most contagious is usually when the symptoms are at their worst, usually 2 to 4 days into the cold.
A clinical horizon would be the time that a disease first started. For example, when a person has heavy metal poisoning, the first time it is noted in the hair sample would be the clinical horizon.
The first step is to have the horse vaccinated against Strangles while the horse is still healthy. If the horse is already sick then do not vaccinate for Strangles as this can worsen the problem. You need to quarantine the horse away from any other horses and have a equine vet come out to check the horse. They will likely take the horses temperature and take a cultural swab from the horses nose. the horse will likely have swollen Lymph nodes and they may open and drain pus. If the test comes back positive the vet will prescribe Penicillin G, which is effect against Strangles. If caught early enough Strangles can be treated without a problem, if left too long however it can become life threatening.
Yes, it is contagious. It is spread easiest between children but adults can get it also. It is most contagious within the first 2 to 4 days when symptoms first appear. However, it may remain contagious up to 3 weeks. Be sure to wash your hands immediately after coughing and/or sneezing to avoid spreading the virus to others. Try to avoid large crowds when contagious. Doctors now recommend getting alot of rest, increase fluids, and treat symptoms as needed with over the counter medications (Tylenol, Motrin, Robitusin, etc.).
First 2-4 days after onset of symptoms.
An upper respiratory infection is contagious for as long as the active virus is in your system. Taking an antibiotic will help rid the body of the live virus. You will remain contagious for 24 hours following the first treatment of the antibiotic.
The tonsils are lymphoid tissue, so enlarged tonsils often indicates the horse's body is reacting to an inflammatory event (infection, auto-immune disease, cancer, trauma) in that area.In the case of the tonsils at the back of the throat, my first reaction would be to suspect infection with Streptococcus equi equi, more commonly called "strangles". This is a highly contagious infection that can run through a herd or stable in a matter of days, and the infection can be fatal if the swelling in the gutteral pouches becomes severe enough.Because of this, I would strongly recommend calling your veterinarian and notifying him/her on the phone that your horse may have strangles so they can take care of appropriate biosecurity to protect the rest of their clients' horses.
