The most common cause of upper respiratory symptoms are viruses. Viruses cannot be treated with antibiotics. Physicians usually recommend rest, fluids and time to allow symptoms resolve.

Some virus infections do cause those symptoms that are like the flu, such as fever, coughs and sneezes, body aches, headaches, malaise and fatigue. However, not all viruses cause these symptoms. The most common viruses to cause these symptoms are the cold and flu viruses and those viruses that cause viral gastroenteritis (also known as "stomach flu", although it is not due to influenza viruses). Viral gastroenteritis is also commonly called Norwalk flu and it is most often due to noroviruses, that are specific to the GI tract, just as influenza viruses are due to viruses that are specific to the respiratory tract.
Usually viruses cause cold-like symptoms, such as the viruses that cause the common cold and the flu, but, other diseases and disorders can also include similar symptoms and so can toxic effects from chemicals and drugs.
While most viruses co-exist harmlessly in their host and cause no signs or symptoms of disease, many of the viruses do cause fever.
Latent
Viruses can cause both vomiting and diarrhea. The "Norwalk Flu" is a name given to what is also commonly called "Stomach Flu", which is gastroenteritis caused by viruses. With it you can get nausea, vomiting, and diarrhea as well as a fever and aches. Many other viruses also can cause these symptoms such as the flu viruses. However, usually there are also obvious respiratory symptoms with influenza that are more severe and last longer than the GI system signs and symptoms.
Inflicted by toxins
Some viruses lack the ability to replicate. These types of viruses often don't show symptoms in healthy people because they are not strong enough to cause illness.
Many bacteria and viruses need time to multiply before any signs and symptoms can be seen.
