7-21 days
Once a cat is exposed to an infectious agent, it will go through an incubation period of 2-10 days before developing symptoms. If the infection is uncomplicated, it will typically last for 7-21 days, depending on the particular disease agent. During this entire time, the cat will potentially be infectious to other cats. With FVR, all cats become chronic carriers, meaning that they will have the disease essentially for life. Middle ear infections usually occur along with an upper respiratory infection (URI), such as a cold. Fluid builds up in the middle ear, creating a perfect breeding ground for bacteria or viruses to grow into an ear infection. A majority of upper respiratory infections are due to self-limited viral infections. Occasionally, bacterial infections may cause upper respiratory infections. Most often, upper respiratory infection is contagious and can spread from person to person by inhaling respiratory droplets from coughing or sneezing. The transmission can also occur by touching the nose or mouth by hand or other object exposed to the virus. Common searches for this page include: what is a cold, what is an upper respiratory tract infection, how do you get colds, treatment for colds, cold treatment, respiratory tract infection treatment, symptoms of upper respiratory tract infections, medicine for upper respiratory tract infections. It depends on a few things. Remember, the antibiotics only work on a bacterial infection and a URI is a virus. The antibiotic takes care of any underlying infections, it does not cure the kitty cold, which a URI is. Make sure you give the antibiotic until it's gone, usually 2 times a day for 7 days. With luck, you'll barely notice you have symptoms. Upper respiratory infections are caused by more than two hundred different viruses, no two exactly alike. Symptoms can last from 24 hours to four weeks. You may have any variation of sore throat, runny or stuffy nose, cough, aches, pains, and a fuzzy head..
