Influenza viruses is a respiratory infection caused by a variety of influenza viruses. It is a contagious infection that can easily spread from person to person and stays in your body for 24 hours. This virus causes infection in your lungs, nose and throat. This infection is very different from that of a common cold and many other respiratory infections.
An affected person can easily spread this virus by just a sneeze. Medically speaking, a sneeze by a infected person can help spread this virus in the form of tiny droplets of respiratory fluids that are dismissed to the air. This means that if anyone is standing next to you or around you, there are high chances that they may get infected.
The worst part of this virus is that it can surface around you for the next 24 hours. This means that the flu can spread when someone touches doorknobs, telephones or even taps in the house. The impact of this disease can be felt in a public surrounding where an infected person sneezes and this will immediately affect his/ her surroundings. So if your child is suffering from influenza virus, it is advised that you don’t send them to school until the virus is gone.
However, a person suffering from influenza virus will be able to recover within 1 or 2 weeks, but if left untreated, an infected person can develop pneumonia. Questions like what can be done to curb this deadly virus and how can it be treated will be further discussed in this article. Before we get into the different types of influenza viruses, let’s understand what is this virus.

What is Influenza Virus?
Influenza virus is a deadly infection that affects your nose, throat and lungs. It is considered to be deadly because it can affect people immediately, especially from their surroundings. This virus is known as the flu, but it is very different from that of stomach flu that causes diarrhoea and vomiting.

It also affects adults who are older than 65 years of age. This virus can also affect pregnant women before or after pregnancy and people who have a weak immune system, people suffering from heart disease, asthma, kidney and liver diseases.
Types of Influenza Viruses:
Influenza viruses enter your body usually through mucus membranes of your eyes, nose and mouth.

Wild aquatic birds often carry influenza A and can cause an outbreak among humans. This can be transmitted to humans thereby causing an outbreak. If one person is infected, then you better be sure that everyone in your surroundings are also going to suffer your plight.
Type B Influenza Virus:
Influenza B affects only humans and is less harmful than influenza A. Type B has the same tendency to affect people on the same lines of type A, but it takes time for a person to get affected. Type B influenza can be identified by symptoms such as running nose, sore throat, fever, muscle and body aches and severe cough.
Type C Influenza Virus:

Risks of Influenza Virus:
Most people who suffer from any flu will get healed in a day or two, but influenza will try and spread the infection and then only leave you. That is why this virus is considered to be deadly.

So make it a point to consult your doctor and stay away from self-medication that will make things worse for you.
Because influenza virus is considered a serious disease that can lead to serious hospitalisation or sometimes death, there is a vaccine that is given on annual basis. This disease has the capability of affecting different people in different ways. It is said that millions of people get this flu annually in which tens of thousands die from this disease world-wide. However, hospitals are making it a point that a vaccine that prevents this flu is given every year. This vaccine reduces the risks of patients getting influenza but is said to have certain side effects.
Types of Influenza Vaccines:
There are usually two types of vaccines that are used to prevent influenza virus. Both these vaccines are used as a tool to prevent influenza and its contagious spreading. These vaccines play an important role in not just preventing the virus, but also providing you the knowledge that this so-called virus does exist. Most people feel that this is treatable by self-medication, but they do not know the complications it involves in it.
Inactivated Influenza Vaccines (IIV):
Inactivated influenza vaccines can be used on individuals who are aged 6 months and above, including pregnant women. It is an injection that is injected into the deltoid thigh. Children between the age group of 6 months and 8 years must receive two doses. In terms of pregnant women, this vaccine will protect both the mother and her newborn against influenza. There may be some side-effects of this vaccine such as swelling near the injected site. In some case, people who have no previous exposure to the vaccine may experience fever and muscle pain.
Live Attenuated Influenza Vaccines (LAIV):
Live attenuated influenza vaccine is another type of vaccine that is in the form of nasal spray. This is also effectively used to curb influenza virus. LAIV is permissible to be used on individuals who are between the age group between 2 to 49 years of age, provided is is advised by a doctor who suggests your body condition is fine to sustain it.
Patients are usually given 1 dose initially and children are given 2 doses in a span of 4 weeks. This vaccine is made from other viruses and it prevents influenza. However, this has certain side-effects such as nasal congestion, fever and a sore throat. Moreover, the side-effects are mild when compared to that of IIV.
Side-effects of Influenza Vaccine:
Usually, influenza vaccines develop antibiotics in your body after two weeks after the vaccination is given. These antibiotics prevent the infection from attacking your body or organs. There are traditional influenza vaccines that are given to protect you from flu viruses and influenza A & B. There are also quadrivalent vaccines that are also given to protect you from an Type B Influenza virus. According to a recent study by the Center for Disease Control and Prevention (CDC), the following have been identified as some of the side-effects of Influenza vaccines.

Influenza Is Wreaking Havoc in Nebraska
– 26th Dec 2018
The Department of Health and Human Rights has reported that more and more schools and day care centers are being shut down in Nebraska because of a wave of cases of influenza amongst the people. The Department of Health and Human Rights has made influenza vaccination its top priorities and is urging all healthcare providing centers to aggressively vaccinate people who have not received their influenza shot for this year. Viral diseases can reach epidemic levels in no time and influenza as a viral infection is especially harmful to pregnant women as well as diabetics. In the case of diabetics, this disease can make it very difficult to monitor and control blood sugar levels effectively. For pregnant women the situation becomes even more complicated as they cannot be given any strong antibiotics as they can end up potentially harming the baby, the fever, on the other hand, is also a fetus harming situation. Thus, the health department is on high alert in Nebraska, ensuring that the virus is contained before it causes much havoc.
Studies Reveal Tethered Antibodies Can Effectively Prevent Influenza Virus
– 30th Nov 2018
In a recent study done by the international collaboration of scientists based from Scripps research found that tethering more than one antibodies together can significantly increase the prevention capabilities against almost all types of influenza virus. The results can prove to be extremely helpful in planning prevention against influenza virus which is known for its ability to mutate swiftly.
The study was conducted by harvesting antibodies from llamas which are highly reduced in size compared to human antibodies helping in seamless bonding together. Even though the concept of tethering anti-bodies together existed for a long time, this is the first time successful results were obtained against influenza A and B virus.
X-ray observation and electron microscopy studies revealed that when combined together these antibodies can effectively target the weak points of the influenza virus and render it harmless. This is a very promising result as this shows that all kinds of influenza virus can be attacked on their weak points by tethered antibodies.
There is still research happening to device an effective strategy to deliver these antibodies into host bodies to enable the host to fight off influenza. Till date, there is no working vaccination against deadly influenza due to their rapidly mutating characteristics. With this new results, scientists believe that influenza virus infections can be successfully curbed.
