In 2018, the World Health Organisation (WHO) mentioned on its website that Influenza disease (Flu) annually causes severe fever in over three to five million people worldwide. Also, it caused around 2,90,000 to 6,50,000 deaths. In fact, you may have caught this disease sometime or the other in your lifetime. Unfortunately, since the Flu virus mutates rapidly and is contagious, you will likely develop this disease again. That is why it is essential to be aware of its symptoms, causes and treatments. In this article, we will be discussing these. So, read ahead!
Influenza or Flu is a viral infection that affects the respiratory system of the body. It is highly transmissible and primarily spreads via respiratory droplets. Thus, it is generally passed on while talking or shaking hands.
The following are the common Flu virus variants.
Influenza A viruses
Influenza B viruses
Influenza C viruses
Influenza D viruses
Flu season is the typical time every year when the Flu virus tends to break out in a geographical region and then eventually subsides. It usually occurs during the cold months of the year. According to the Centres for Disease Control and Prevention (CDC), the Flu season in India is in full swing during the monsoon seasons (June to September) and again tends to rise in the winter months (November to February).
Flu virus symptoms generally start to show up around one to seven days after the virus has entered the body. The following are some of the common Flu symptoms.
Chronic Obstructive Pulmonary Disease (Cold) and the Flu are highly transmissible respiratory diseases that share some common symptoms but have different causes. As mentioned earlier, the Flu is caused by the Influenza virus. However, Colds can be caused by multiple different types of viruses.
The following are some of the symptoms that both these respiratory diseases share.
Blocked or runny nose
Discomfort in the chest
Despite the commonalities in symptoms between Cold and the Flu, there are also major differences. The below-given table shows the key differences in their symptoms.
The below-mentioned table shows the warning signs of the Flu in children and adults. If you or your child develops any of these symptoms, get medical attention at the earliest.
|Warning signs of Flu in children||Warning signs of Flu in adults|
|Sore muscles, Breathing difficulty, Chest discomfort, Seizures, High fever, Contracting ribs while breathing, Recurring cough and fever, Bluish face or lips, Dehydration, Worsening of preexisting health conditions, Inability to focus||Inability to urinate, Chest discomfort, Breathing difficulty, Seizures, Weakness, Confusion, Dizziness, Worsening of preexisting health conditions, Recurring cough and fever, Sore muscles|
Here’s how the Flu virus develops in your body.
The virus enters the body either through the eyes, nose or mouth.
After around 24 hours, the person may be able to transmit the virus to others through close contact.
Symptoms may start to appear after one or two days from the beginning of the infection.
The transmissibility of the virus reaches its peak around three or four days after the symptoms develop.
After around four days from the start of the infection, the muscle aches and fever start to subside.
After the completion of around a week, most symptoms fade away.
The transmissibility of the virus starts to decrease from the fifth day since the initiation of the symptoms.
Some symptoms of the Flu like cough and tiredness may subside only after the completion of one more week.
Influenza is usually transmitted in the air when a person with the infection sneezes, coughs or talks. You can catch the Flu through droplets in the air or by touching objects that the infected person has touched and subsequently touching your own eyes, nose or mouth.
The Flu virus can spread even before the onset of its symptoms and is generally contagious up to five days from the start of the infection. The disease is typically contagious for a longer duration in children and individuals having a compromised immune system.
The following factors make you more susceptible to developing the Flu.
Age: Influenza tends to develop more in young children (below the age of 5 years) and older adults (above the age of 65). Also, youngsters under the age of 19 undergoing aspirin therapy are likely to develop a health condition called Reye's Syndrome if they get infected with the Flu.
Obesity: Individuals with an above-normal body mass index are at an increased risk of developing Flu-related health complications.
Compromised immune system: Certain treatments and medications for HIV/AIDS, cancer and organ transplant procedures may temporarily suppress your body’s immune response. This may increase the risk of you catching the Flu and developing further complications.
Living or working environment: Individuals residing in a crowded place like an old-age home or a hostel are more prone to Flu. Professionals working in a hospital environment are also at higher risk of catching the disease.
Pregnant women: In their second and third trimesters, pregnant women are more prone to developing Flu-related complications. This threat is also there for women who have completed two weeks since their child's delivery.
Chronic illnesses: Suffering from certain chronic preexisting health conditions like metabolic disorders, asthma and heart disease may increase your risk of developing Influenza-related complications.
Flu is generally treated at home. The following are some of the treatment methods.
Painkillers can help to relieve body pain and headache.
There are other over-the-counter antiviral medications you can buy as per your doctor’s recommendations.
Drink plenty of fluids like juices and soups to combat dehydration.
Get more rest. This may give your immune system a better chance of fighting off the infection rapidly.
Here are some tips that may help you avoid catching the Flu.
Avoid contact with people who have symptoms of the Flu.
Wash your hands regularly and maintain good hygiene.
Since smoking can aggravate Influenza, it is advisable to avoid or minimise it.
Eat regularly and maintain a healthy diet. This will strengthen your immune system and prevent the development of diseases.
An annual Flu shot or vaccination is the most effective way to prevent the development of Flu. It is injected into the body via the arm and can be taken by anyone older than six months. Another method for vaccination is the nasal-spray Flu vaccine. As its name suggests, this vaccine is administered through the nose.
Here are the answers to some of the most commonly asked questions about the Flu.
No, consuming antibiotics is not a treatment for Influenza. Antibiotics are medications used to treat bacterial infections. Influenza is a viral infection and so is generally treated with antiviral medication.
No, babies cannot receive a Flu shot. This is because it may be harmful to them.
Yes, a pregnant mom can get a Flu shot. This will safeguard herself and her child from the Flu virus.
Stomach flu typically develops in the digestive system of the body and is different from Influenza. It is caused by the consumption of contaminated food items.
Usually, you do not need to visit a doctor if you develop the Flu since it can be treated at home. However, visit a doctor if you fulfil one or more of the following conditions.
You suffer from a preexisting health condition.
You have a weakened immune system due to the consumption of medication or some disease.
If you are below the age of five years or above the age of 65 years.
If your temperature doesn’t decrease after four to five days of continuous fever.
If the Flu symptoms get worse.
If you have difficulty breathing or suffer chest pain.
