What is the Causing agent of AH1N1?

The H1N1 flu, commonly known as swine flu, is primarily caused by the H1N1 strain of the flu (influenza) virus. H1N1 is a type of influenza A virus, and H1N1 is one of several flu virus strains that can cause the seasonal flu.

What is the causative agent of influenza?

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.

Which pathogen causes H1N1?

The only pathogen identified was an H1N1 strain of swine influenza virus.

What type of virus is H1N1?

influenza A H1N1, also called influenza type A subtype H1N1, virus that is best known for causing widespread outbreaks, including epidemics and pandemics, of acute upper or lower respiratory tract infection. The influenza A H1N1 virus is a member of the family Orthomyxoviridae (a group of RNA viruses).

How does H1N1 affect the body?

Usually, the first effect of swine flu on the body is a fever with chills and muscle aches. You may also have a feeling of general weakness, fatigue, and a headache. Remember, swine flu is caused by a virus that infects the respiratory system. As a result, effects on the body often focus on the throat, nose, and lungs.

What is the pathophysiology of influenza?

The primary mechanism of influenza pathophysiology is a result of lung inflammation and compromise caused by direct viral infection of the respiratory epithelium, combined with the effects of lung inflammation caused by immune responses recruited to handle the spreading virus (Table 1).

What causes Covid 19?

Infection with severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2, causes coronavirus disease 2019 ( COVID-19 ). The virus that causes COVID-19 spreads easily among people.

Why is H1N1 influenza called swine flu Brainly?

An outbreak of a previously unknown strain of H1N1 occurred in 2009. Originally called swine flu because the virus was suspected to have been transmitted to humans from pigs, the illness first broke out in Mexico and then spread to the United States.

Can you catch H1N1 twice?

Is it possible to catch A(H1N1) twice? Yes, because the virus can mutate (change). If you become infected with the swine flu virus, your body produces antibodies against it, which will recognize and fight off the virus if the body ever meets it again.

How did humans get swine flu from pigs?

A. Flu viruses are thought to spread among pigs in the same way that human influenza viruses spread among people. That is mainly through close contact between infected and uninfected pigs and possibly from contact by an uninfected pig with an object contaminated by an infected pig.

Is the Spanish flu H1N1?

Spanish flu, also known as the Great Influenza epidemic or the 1918 influenza pandemic, was an exceptionally deadly global influenza pandemic caused by the H1N1 influenza A virus.

Is influenza RNA or DNA?

All influenza viruses consist of single-stranded RNA as opposed to dual-stranded DNA.

Is Zika virus a disease?

Key facts. Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes, which bite during the day. Symptoms are generally mild and include fever, rash, conjunctivitis, muscle and joint pain, malaise or headache.

What is the epidemiology of influenza?

Yearly influenza epidemics can affect all populations, but children younger than the age of two, adults older than 65, as well as people with chronic medical conditions or weakened immune systems, bear the highest risk of complications. The annual attack rate is estimated at 5–10% in adults and 20–30% in children.

What causes influenza and pneumonia?

Common Causes of Pneumonia

Viruses, bacteria, and fungi can all cause pneumonia. In the United States, common causes of viral pneumonia are influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 (the virus that causes COVID-19). A common cause of bacterial pneumonia is Streptococcus pneumoniae (pneumococcus).

What type of transmission is influenza?

This droplet transmission of the flu is known as contact transmission. The influenza viruses can also be transmitted by indirect contact by touching a contaminated object or surface and then touching your own mouth, eyes or nose before washing your hands.
