Question: What Illnesses Can Be Asymptomatic?

Can you have influenza and be asymptomatic?

As many as 50% of infections with normal seasonal flu may be asymptomatic, which may in part be due to pre-existing partial immunity [1].

Asymptomatic patients shed virus and can transmit the disease, but not at the same rate as symptomatic individuals, which creates an invisible “reservoir” for the virus..

What does symptomatic treatment mean?

Symptomatic treatment: Therapy that eases the symptoms without addressing the basic cause of the disease. For example, symptomatic treatment of advanced lung cancer that has spread (metastasized) beyond the lung is designed to decrease the pain and other symptoms but not to eradicate the disease.

How long should you stay home with the flu?

Individuals with suspected or confirmed flu, who do not have a fever, should stay home from work at least 4-5 days after the onset of symptoms. Persons with the flu are most contagious during the first 3 days of their illness.

What percentage of flu patients are asymptomatic?

The prevalence of asymptomatic carriage (total absence of symptoms) ranged from 5.2% to 35.5% and subclinical cases (illness that did not meet the criteria for acute respiratory or influenza-like illness) from 25.4% to 61.8%.

What is a symptomatic condition?

Who gets the flu most often?

The same CID study found that children are most likely to get sick from flu and that people 65 and older are least likely to get sick from influenza. Median incidence values (or attack rate) by age group were 9.3% for children 0-17 years, 8.8% for adults 18-64 years, and 3.9% for adults 65 years and older.

How long does it take to get over influenza B?

As harsh as the flu can be, the good news is that most people feel much better within one to two weeks. Most healthy adults become contagious the day before symptoms develop (which makes it trickier to prevent from spreading).
