Avian influenza is one of many types of infectious diseases that pose a threat to public health. Below is a comparison of bird flu to other infectious diseases such as seasonal flu, SARS and COVID-19.

   Avian flu vs seasonal flu

  Seasonal flu is a viral infection that affects millions of people around the world every year. Like bird flu, it is caused by influenza viruses, but they differ in several key aspects.

    Scope: Seasonal flu is widespread and occurs worldwide, while avian flu is rarer and concentrated mainly in certain regions, such as East Asia.

    Mortality: Although both diseases can be fatal, avian flu has a much higher mortality rate than seasonal flu.

    Transmission: Seasonal flu is easily transmitted between humans, while avian flu is usually transmitted from birds to humans, with rare transmission between humans.

   Avian flu vs SARS

  SARS (severe acute respiratory syndrome) is a disease caused by the SARS-CoV coronavirus, which caused outbreaks in 2002-2003.

    Symptoms: Both SARS and bird flu can cause severe respiratory symptoms, but bird flu can also lead to other problems such as encephalitis.

    Transmission: Both SARS and avian flu come from animals - SARS most likely passed to humans from bats, and avian flu from birds.

    Scope and mortality: Although both diseases are serious, SARS affected fewer people worldwide compared to bird flu, but had a higher mortality rate.

    Avian flu vs COVID-19

  COVID-19, caused by the SARS-CoV-2 coronavirus, is currently the most common infectious disease.

    Transmission: Like avian flu, COVID-19 is transmitted from animals to humans, but unlike avian flu, it is easily transmitted between humans.

    Symptoms: COVID-19 and avian flu can cause similar symptoms, such as fever, cough and difficulty breathing, but avian flu is usually more severe and has a higher mortality rate.

  In summary, avian influenza is a serious infectious disease that differs from other diseases such as seasonal influenza, SARS and COVID-19 in various aspects such as transmission, extent, symptoms and mortality. It is important to understand these differences to ensure effective prevention and response to these diseases.
