Signs of the Flu

Duration of the common flu suffering

Common flu does not last for more than one or two weeks. For children, the flu might be longer. The reason is, in the case of children, the disease is not that easy to detect. Children suffer from various diseases. That is why the parents take a longer time to detect common flu. However, for children, the flu is easily curable. The recovery time is short for younger adults too.

For senior patients, the signs of the flu are easily detectable. But older adults suffer for a much longer time. As older people’s immunity system is much weaker than younger people, they take a longer time to recover. In extreme severity, older people can suffer for a longer time than they expect the symptoms. They might not have a fever or the flu, but they can be tired and weak for weeks. Moreover, the duration of the common flu suffering differs according to the patient’s medical condition.

The groups with the major risk of common flu infection

Although anyone can get influenza infection anywhere at any age, some age groups are the most susceptible. There are almost ten thousand cases of common flu that occur in India. And that, too, is the official statistics. There are many more cases that go undetected and unregistered. So, this flu is like any other common disease that threatens the entire population. However, there are people of certain age groups who are particularly at risk of this flu. Here is a list of the age groups who should be more careful:

Infant and Children

The first age group under the risk of getting infected is the babies of one to two years. Common flu is one of the most frequent ailments that babies of this age suffer. The second group would be the toddlers of three to five years. As infants of this age tend to lick everything, they have chances of having common flu.

Another reason behind the higher susceptibility of children is their weaker immunity system. That is why, if anyone with infection comes near them, they tend to get the infection. Even children between the age group of six to 13 can be highly at risk of getting the infection.


The main risk of infection among adult people is their higher chances of exposure. The young adults are yet less vulnerable as they have high immunity power. On the other hand, the late adults between the age groups of forty to fifty are more prone to get common flu. Their immunity system does not allow them to stay immune to the infection of this flu.

The elderly

Senior people often suffer from influenza or the common flu, partly because of their failing immunity. Another reason behind this is the fact that older adults have other different medical conditions. Most of the older people around us suffer from various other ailments, such as diabetes, a higher rate of blood pressure, etc. This plethora of diseases makes them more vulnerable to common flu infection. Some old persons have chronic illnesses that give them a reason to be vulnerable to the common flu. In one word, people between the ages of 60 and 80 are at higher risk of suffering from common flu pangs.

Social groups that are under risk

Apart from those particular age groups, other social and medically deviant groups tend to get the virus infection. For instance, pregnant women are at risk of this flu. During pregnancy, women are vulnerable to a variety of diseases and infections. This common flu could be a real headache for pregnant women. Secondly, people with any chronic diseases can easily get the infection. People with cancer are very vulnerable to this infection too. Cancer patients take several medicines that lower their immunity power. Hence, they have a higher risk of getting affected.
