Which Type Of Bird Flu Is In The News

Health care professionals had been very vocal about the strain of avian influenza known as H5N1.

The reason H5N1 has caused so much alarm is its ability to pass from wild birds to poultry and then on to people. While wild birds are commonly immune to the devastating and possibly deadly effects of H5N1, the virus has killed more than half of the people infected with it. The risk of avian flu is generally low in most people because the virus does not typically infect humans. Infections have occurred as a result of contact with infected birds. Spread of this infection from human to human has been reported to be extremely rare.

Viruses can be transmitted when you touch a surface that is contaminated and then touch your eyes, nose, or mouth. They can also be transmitted by contaminated water or food. Some viruses are spread through sexual contact or through contact with blood via needle or transfusion.

Influenza A vs B

Influenza is the common viral infection, which is commonly called the flu. This infection is common to mammals as well as birds. The viruses are all belong to the group orthomyxoviridae. There are three types of influenza viruses. They are type A, B and C. Even though the virology may differ from one infection to the other, general features, symptoms, investigations and diagnosis, treatment, prevention and prognosis go along similar principles.

Full blood count may show a response to infection. Viral cultures may be used to confirm the diagnosis if doubts are there. Drinking a lot of fluids, bed rest, and good nutrition are very important to aid recovery. Antivirals are needed only in severe disease. Neuraminidase inhibitors and M2 inhibitors are the most commonly used antiviral drug classes. Prevention of influenza is difficult because of it can spread along many pathways. Good hygiene, hand washing, using separate utensils, and wearing masks may go a long way towards limiting spread. There is a flu vaccine available. It is recommended to healthcare workers, children, elderly, and people with long standing diseases. This vaccine can even be given to HIV/AIDS patients, post-transplant patients, and those who are on immuno-suppressive drugs. Because influenza viruses mutate and change rapidly, vaccination does not confer lifelong immunity. The protection lasts for about two to three years.

The flu typically comes on strong, causing excessive fatigue, weakness, chills, and body aches that improve gradually. For all its similarities, acute bronchitis is mainly defined by a nagging, persistent cough that emerges more gradually and changes over time.

Given that bronchitis is a common complication of influenza, however, its entirely possible to come down with the flu and wind up with a lingering case of acute bronchitis.

Whenever you develop a major respiratory infection, its important to seek a proper diagnosis no matter what you think you have. Just as treatment options can vary from one respiratory illness to the next, complication risks can vary from one person to the next.

What Causes The Flu

The flu is caused by influenza viruses that infect the nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby. You can also get flu by touching a surface or object that has flu virus on it and then touching your own mouth, eyes or nose.

You can spread the flu before you know you are sick, beginning 1 day before symptoms develop and up to 5 to 7 days after becoming sick. Some people, especially young children and people with weakened immune systems, might be able to infect others for an even longer time.

If a person has COVID-19, they could be contagious for a longer time than if they had flu.

Most people with flu are contagious for about 1 day before they show symptoms.

Older children and adults with flu appear to be most contagious during the initial 3-4 days of their illness but many people remain contagious for about 7 days.

Infants and people with weakened immune systems can be contagious for even longer.


How long someone can spread the virus that causes COVID-19 is still under investigation.

Its possible for people to spread the virus for about 2 days before experiencing signs or symptoms and remain contagious for at least 10 days after signs or symptoms first appeared. If someone is asymptomatic or their symptoms go away, its possible to remain contagious for at least 10 days after testing positive for COVID-19. People who are hospitalized with severe disease and people with weakened immune systems can be contagious for 20 days or longer.
