Through your nose or throat.
most likely enters through nose,mouth or eyes.
No, influenza is caused by viruses, specifically the influenza virus. Influenza viruses can infect the respiratory tract and lead to symptoms such as fever, cough, and body aches. Antibiotics, which are used to treat bacterial infections, are not effective against the influenza virus.
The entry point for the influenza virus is typically through the respiratory tract, such as the nose or mouth, when an infected person coughs or sneezes, releasing virus-containing respiratory droplets into the air. These droplets can then be inhaled or enter the body through contact with contaminated surfaces.

Influenza is considered an active virus. It is an RNA virus that actively replicates and spreads in the host's respiratory system, leading to illness. Unlike hidden viruses, such as those that establish latency (like herpes viruses), influenza does not remain dormant in the body; it typically causes symptoms shortly after infection and is associated with seasonal outbreaks.
Influenza primarily infects birds and mammals, including humans. It is a virus that affects the respiratory system and can cause symptoms such as fever, cough, and body aches.
Pathogens. These are typically bacteria, viruses, fungi, or parasites that can cause disease by invading the body's tissues. Common examples include influenza viruses, E. coli bacteria, and malaria parasites.
the influenza virus is just another name for the flu......you know runny nose, high fever, and such.
The flu virus enters the body by attacking the cells of mucous tissue. Usually this is the tissue in the upper respiratory tract with influenza viruses. Typically the virus enters via the mouth, nose or eyes. Since the gastrointestinal system is also lined with mucous tissue, the influenza viruses can also enter cells deeper in the GI system and not just in the mouth. When this happens, the symptoms can include gastrointestinal reactions to the virus and to the cells the virus enters being killed, which gives GI symptoms like vomiting, nausea and even diarrhea along with the usual respiratory symptoms.
The respiratory system is the first system targeted and hit in any influenza. Although stomach and GI viral infections are sometimes called "stomach flu", those are not really caused by an influenza virus, it is another kind of virus. As influenza worsens in some individuals other body systems can be severely affected secondarily, such as renal (kidneys), central nervous system (fever induced seizures), etc.
Flu viruses cause disease, they cause influenza (flu). They are the infectious agents of the flu. The viruses are submicroscopic organisms that infect your body and that give you the influenza, the disease.
Because your body is fighting the sickness off, which is where the heat comes from. Its just like any other sickness.
