Influenza – Introduction
Influenza, commonly known as the flu, is a highly contagious viral infection that affects the respiratory system. The influenza virus, a member of the Orthomyxoviridae family of viruses,causese the flu. The flu itype typicallyspreadsdsh contact with an infected person’s respiratory secretions, such as saliva, mucus, or blood. The flu can also be spread through contact with contaminated surfaces, such as doorknobs, door handles, or countertops. The flu can cause severe respiratory illness, and sometimes, it can lead to death. The flu can severe serious complications, such as pneumonia, and can be fatal in some cases. The best way to prevent the flu is to get vaccinated each year.
Symptoms of Influenza
The symptoms of influenza can vary from person to person, but the most common symptoms include the following:
- fever
- chills
- body aches
- headache
- fatigue
- coughing
- sore throat
- runny nose
Some people may also experience nausea, vomiting, and diarrhoea. Influenza can sometimes lead toseveres complications, such as pneumonia, which can be deadly.
Most people who get influenza will recover within a week or two, but some may develop serious complications, such as pneumonia, which can be deadly. Influenza is more likely to cause severe illness in young children, older adults, pregnant women, and people with chronic medical conditions, such as asthma, heart disease, and diabetes.
If you have any of the above symptoms, you should see a doctor as soon as possible, as early treatment can help prevent complications.
Diagnosis of Influenza
The best way to diagnose influenza is to see your doctor and get a rapid influenza diagnostic test (RIDT). RIDTs are quick, easy, and usually accurate. They work by detecting influenza viruses in a respiratory specimen, such as a nose or throat swab. However, RIDTs are imperfect and sometimes give false positive or negative results.
If the RIDT is positive, this usually means that you have influenza. However, if the RIDT is negative and your doctor thinks you might still have influenza, they might order other tests, such as a viral culture or antigen detection test. These tests take longer to get results back (usually 1-2 days) but are more definitive.
The most important thing to remember is that if you think you might have influenza, see your doctor right away. Early diagnosis and treatment are critical to preventing severe complications from the flu.
How is Influenza spread?
The flu is spread mainly by droplets made when people with the flu cough, sneeze, or talk. These droplets can land in the mouths or noses of nearby people. Less often, a person might also get the flu by touching a surface or object with the flu virus and then touching their mouth or nose.
People with the flu are most contagious in the first 3-4 days after their illness begins. Some people, especially young children and people with certain chronic medical conditions, might be contagious for longer.
If you have the flu, you should stay home for at least 24 hours after your fever is gone, except to get medical care or other necessities. You should also stay away from other people as much as possible to avoid making them sick.
Treatment of Influenza
The flu, or influenza, is a contagious respiratory illness caused by viruses. It can cause mild to severe illness and, at times, can lead to death. The best way to prevent the flu is by getting a flu vaccine each year.
There are two main types of influenza viruses: A and B. These viruses constantly change, so the flu vaccine is updated yearly to protect against the most recent strains.
The flu vaccine is made from inactivated (killed) viruses and is safe for most people. There are three types of flu vaccines:
- The trivalent flu vaccine protects against three flu viruses (two A viruses and one B virus).
- The quadrivalent flu vaccine protects against four flu viruses (two A viruses and two B viruses).
- The cell-based flu vaccine protects against three flu viruses (two A viruses and one B virus).
The flu vaccine is recommended for everyone six months of age and older. It is significant for people at high risk of developing severe complications from the flu, such as:
- People with chronic medical conditions, such as asthma, diabetes, and heart and lung disease
- People 65 years of age and older
- Pregnant women
- Children younger than five years old, but especially children younger than 2 twoears old.
The flu vaccine is also recommended for people who live with or care for people at high risk of developing severe complications from the flu. This includes:
- Healthcare workers
- Household contacts of people with chronic medical conditions
- Household contacts and caregivers of children younger than five years old, but especially children younger than 2 twoears old
The best way to prevent the flu is by getting a flu vaccine each year. There are two main types of influenza vaccines: the trivalent vaccine and the quadrivalent vaccine. The trivalent vaccine protects against three different flu viruses, while the quadrivalent vaccine protects against four. The cell-based flu vaccine is also available and protects against three.
Prevention from Influenza

The flu can also be spread through contact with infected people, such as by shaking hands or sharing utensils.
The flu is a severe illness that can lead to complications, such as pneumonia, bronchitis, and sinus infections. The flu can also exacerbate medical conditions like asthma and heart disease.
