Rhinoviruses and group A streptococci may incubate for 1-5 days, influenza and parainfluenza may incubate for 1-4 days, and respiratory syncytial virus (RSV) may incubate for a week. Pertussis typically incubates for 7-10 days, or even as long as 21 days, before causing symptoms. Diphtheria incubates for 1-10 days.

It has an incubation period of about 12 - 48 hours, and can cause the person to be contagious during the incubation period and for as long as they shed virus (usually about three days after symptoms stop but sometimes up to two weeks).

An upper respiratory infection (URI) is a viral infection that affects the respiratory system, including the ears, sinuses, nose, or throat. The common cold is the most frequently caught form of an upper respiratory infection.

The incubation period — the time between exposure to the bacteria and the onset of illness — is between 3 and 21 days. Symptoms typically appear within 14 days of initial infection. Infections that occur faster after exposure are typically more severe and have a worse prognosis.

Some of us have meningitis-causing bacteria in our throats or noses. Even if we don't get sick, we can still spread it to others. According to the World Health Organization , the incubation period is between two and 10 days. The largest concentration of meningococcal disease is in sub-Saharan Africa.

An upper respiratory infection (URI) is a viral infection that spreads from one person to another irritating the nose, throat, and lungs. It often comes with congestion and a nagging cough. The phlegm, mucus, and discharge from the infection can have a metallic taste that enters your mouth when coughing.

"The typical upper respiratory infection involves the nose and throat..." The typical upper respiratory infection involves the nose and throat, causing symptoms such as sneezing, nasal congestion, conjunctivitis (inflammation of the membranes lining the eyelids), and discharges from the nose or eyes.

The incubation period for tonsillitis is generally between two and four days. If you think you've been exposed to germs but don't develop symptoms within this timeframe, there's a chance that you may not develop tonsillitis.

After an incubation period of, usually, 2–3 weeks, disease symptoms may appear but more frequently they do not. A serious clinical picture can suddenly emerge characterised by high fever, eye infection, respiratory tract infection, and severe headache.
376598
It can take four to six weeks from when you're first infected for symptoms like fatigue, a sore throat, and muscle aches to appear. This is called the incubation period. Once your symptoms do appear, they may last for two to four weeks.
15662
Most often, upper respiratory infection is contagious and can spread from person to person by inhaling respiratory droplets from coughing or sneezing. The transmission of respiratory infections can also occur by touching the nose or mouth by hand or other object exposed to the virus.
725598
The incubation period is variable. It occurs commonly around 4–10 days.
1451709
Signs and symptoms The incubation period of the CMV virus varies but symptoms usually become apparent about three to 12 weeks after exposure to the virus. Duration of symptoms also varies, though on average they last for two to three weeks.
684201
The incubation period for a cold is between one and four days. It's typically most contagious a day or two before symptoms appear but can be passed along when the cold is already under way. Once the really runny nose dries up, it's less contagious.
1459976
The incubation period is fairly short, between 1 and 5 days and infected persons can transmit influenza 1-2 days before they have symptoms to 4-5 days after the onset of symptoms. The influenza season in the U.S. usually occurs between December and March.
598734
It takes a while for mono symptoms (like tiredness, fever, muscle aches, headache, or sore throat) to show up — about 1–2 months, in fact. This is called the incubation period. To make things even more confusing, some people can carry the virus without ever getting any mono symptoms.

An acute URI is a contagious infection of your upper respiratory tract. Your upper respiratory tract includes the nose, throat, pharynx, larynx, and bronchi. Without a doubt, the common cold is the most well-known URI. Other types of URIs include sinusitis, pharyngitis, epiglottitis, and tracheobronchitis.
