Influenza, What Causes Flu

Influenza or flu is an infectious disease caused by an influenza virus. it called seasonal influenza because it occurs primarily in the colder months. Symptoms can be mild to severe depending on the resistance. Influenza is an acute viral respiratory infection that causes significant morbidity and mortality worldwide. Flu infected up to 26 million people in the United States in just four months and has killed 25,000 people so far. Despite that, people don’t care and infected individuals face it by consuming soap and analgesics. So far Flu killed more people than coronavirus. Meanwhile, the world is busy with the coronavirus, Flu still kills more people. 

Three distinct types of influenza viruses that infect humans

There are three types of influenza which cause disease in humans. Influenza A, B, and C. Type A is a type which is responsible for causing pandemics. That is because of its high susceptibility to antigenic variation. Influenza A infects multiple species, including humans, swine, equines, and birds. 

Symptoms of flu

The most common symptoms of flu include high fever, runny nose, sore throat, discomfort, pharyngitis, shortness of breath, muscle and joint pain, or myalgia and fatigue, headache, coughing as well as Haemoptysis and feeling tired. In some cases, diarrhea and vomiting can occur in “stomach flu”. These symptoms typically begin two days after exposure to the virus and last more than one week. Some of the complications of influenza may include viral pneumonia, secondary bacterial pneumonia, brain cell loss, sinus infections, and worsening of previous health problems such as asthma or heart failure.
