Question: Can You Be Asymptomatic With H1n1?

Are there asymptomatic flu carriers?

One in three influenza-infected individuals is asymptomatic..

Can the common cold be asymptomatic?

Can someone be infected with a cold virus and not show symptoms? Yes, it is even possible to be exposed to cold viruses and not become infected. When people are infected, they can be asymptomatic (i.e., showing no symptoms); this is called a sub-clinical infection since the infection is not causing a disease.

Which is worse flu A or B?

Influenza type A and type B are similar, but type A is overall more prevalent, sometimes more severe, and can cause flu epidemics and pandemics.

Is flu A virus or bacteria?

What is Influenza (Flu)? Flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs. It can cause mild to severe illness, and at times can lead to death.

How did h1n1 spread so quickly?

Swine flu is very contagious and is easily spread from humans after contact with pigs. The infection rapidly leads to moderate to severe symptoms and deaths are not rare. The key is to prevent the infection in the first place.

Can all viruses be asymptomatic?

However, as the tip of the iceberg, every symptomatic case may represent several asymptomatic cases. Asymptomatic infections span the entire microbiome: viruses [1] , bacteria [2] , parasites [3] , and fungi [4] .

How long are you contagious with h1n1?

People with H1N1 flu virus infection should be considered potentially contagious one day before the onset of symptoms and as long as they are symptomatic, and possibly up to 7 days following the onset of illness. Children, especially younger children, might be contagious for longer periods.

What percentage of flu cases are asymptomatic?

That’s greater than for the flu; about 16 percent of flu cases are asymptomatic, a recent Center for Infectious Disease Research and Policy report notes.

Is a viral disease?

Viral diseases are extremely widespread infections caused by viruses, a type of microorganism. There are many types of viruses that cause a wide variety of viral diseases. The most common type of viral disease is the common cold, which is caused by a viral infection of the upper respiratory tract (nose and throat).

What viruses can be asymptomatic?

Asymptomatic carriers play a critical role in the transmission of common infectious diseases such as typhoid, HIV, C. difficile, influenzas, cholera, tuberculosis and COVID-19, although the latter is often associated with “robust T-cell immunity” in more than a quarter of patients studied.

How long can you be asymptomatic with the flu?

For influenza, it’s one day before symptoms, and five to seven days after the onset of symptoms. It can be as long as 10 days. Young children and patients with altered immune symptoms can shed the virus for longer periods of time.

How long does it take to get over h1n1?

Most people who get the flu (either seasonal or 2009 H1N1) will have mild illness, will not need medical care or antiviral drugs, and will recover in less than two weeks. Some people, however, are more likely to get flu complications that result in being hospitalized and occasionally result in death.

Can viral infection be asymptomatic?

Asymptomatic, chronic viral infections occur in a large portion of humanity. It has been estimated that on average every human being can be concurrently infected with 8–12 chronic viral infections, caused either by DNA or RNA viruses [1].
