4 early signs of viral infections

A viral infection can seem similar to a bacterial infection because of an overlap in their symptoms. However, viruses are much tinier than bacteria and need a host to survive, making treatment of viral infections differ from bacterial ones. Viruses can cause many diseases by attacking certain cells like those in the respiratory system, liver, and blood. Here are a few early signs of a viral infection that one can observe:

Flu symptoms
Fever, body aches, headache, and fatigue are some of the telltale signs of a viral infection like influenza. These symptoms can vary from mild to severe and may require immediate treatment. The symptoms here may develop suddenly instead of gradually, so it is important to seek a prompt diagnosis when one observes any of the abovementioned signs. Those with flu symptoms usually recover in less than two weeks, however, some people may experience serious complications like pneumonia.

Upper respiratory symptoms
Another common type of symptom to recognize is respiratory issues, like persistent sore throat, coughing, nasal congestion, and sneezing. Sinus or ear infections are some of the complications that can develop due to a viral infection. In severe cases, the virus can cause extreme inflammation in the respiratory system, which can lead to sepsis—the body’s extreme response to an infection. It is referred to as an emergency situation requiring immediate treatment. Usually, the reaction starts in the lung and moves on to the urinary tract, skin, and gastrointestinal tract. Without immediate intervention, sepsis may lead to tissue damage and organ failure.

Digestive issues
When dealing with a viral infection, one may experience digestive problems like vomiting, nausea, and also diarrhea. Also known as stomach flu, viral gastroenteritis is an infection in the intestines. Having contaminated water or unhygienic food are common risk factors for this disease, so one of the best ways to prevent the onset of this viral infection is to avoid food and drinks that have unknown ingredients and are not prepared in a sanitized setting. One should also wash hands thoroughly before eating anything. Those with good immunity may be able to fight the infection, but those with compromised immunity may need longer to recover. Stomach flu symptoms usually develop 1 to 3 days after the virus has entered the body and can range from mild to severe.

Skin problems
Rashes, sores, warts, and blisters may also be early signs of a viral infection attacking the skin. Sometimes the virus is in the body, and other times it could affect the skin and find other hosts upon contact. A few examples of viral skin infections are measles or German measles; hand, foot, and mouth disease; chickenpox; monkeypox cold sores; herpes.

These viruses can enter the body through the nose, mouth, eyes, anus, genitals, and skin (injured or broken). So, one should be mindful of the surroundings, practice good hygiene, choose safe food and water sources, and wash their hands thoroughly before and after meals. Covering the nose and the mouth with a mask can also help. One should also sanitize and disinfect daily-use surfaces and hands frequently.

Learn about these 3 types of hearing loss

Hearing loss, deafness, or impairment is the partial or total inability to hear sounds. People with low to moderate hearing impairment face challenges in understanding what the other person is saying in a noisy environment. Whereas, people with severe deafness cannot hear anything, and rely completely on lip-reading and sign language skills. There are three main types of hearing loss: sensorineural, conductive, and a combination of both. Let’s understand these types in detail and learn about the causes, symptoms, and treatments of each type. Sensorineural hearing loss It’s the most common type of hearing loss. Sensorineural is permanent hearing loss often caused by damage to the tiny hair cells that line the inner ear or the auditory nerve. The damage stops or weakens the transfers of nerve signals to the brain. These signals are essentially the intensity and clarity of sounds. Causes: Aging and exposure to loud noises for a long period of time are the most common cause of the damage. Certain medications and illnesses can also increase risks. It can even be genetic, and pass on to the child in the mother’s womb. Treatment: There is no medical or surgical treatment available to repair the tiny hair cells once they’re damaged.

How to distinguish between heartburn and GERD

How to distinguish between heartburn and GERD

Heartburn is an unpleasant, burning sensation in the chest that is more common than a lot of individuals realize. Pregnant women, older men, and even young adults experience it frequently. Despite it being such a prevalent experience, not many know that heartburn has actually nothing to do with the heart and everything to do with the stomach and the esophagus. Unsurprisingly enough, heartburn is also used interchangeably with GERD. But, before we get to deciphering heartburn and GERD, let’s understand what acid reflux is. What is acid reflux or GER? Acid reflux occurs when the lower esophageal sphincter or LES becomes weak, allowing the contents of the stomach to travel in the wrong direction, back up the esophagus. Acid reflux is also called GER or gastroesophageal reflux as it involves the stomach and esophagus. This condition can usually be resolved with over-the-counter medication. What is heartburn? Heartburn is a burning or painful sensation that is experienced in the chest. Since the lining of the esophagus is not as strong as the lining of the stomach, the acid from the stomach can cause a burning sensation in the chest. This pain or burning sensation that is heartburn can often be misconstrued for a heart attack.
5 common joint conditions and how to treat them

5 common joint conditions and how to treat them

A joint or articulation is made from two bones that aid the body in movement. There are many forms of joint conditions, which, in many cases, arise from the wear and tear of bones. Arthritis is one of the major and most common health conditions in the country, and its intensity increases with age. Here are some common types of joint conditions that you need to know: Osteoarthritis With almost 10 percent of men and 13 percent of women aged over 60 suffering from osteoarthritis, it is one of the most prevalent joint conditions in the country. Osteoarthritis occurs due to the wear and tear of the cartilages that protect the ends of bones. It commonly affects joints of the spine, hands, hips, and knees. If left untreated, this wear and tear of the cartilage soon leads to bone degeneration, thereby affecting flexibility and range of movement. Treatment for osteoarthritis depends on its severity and the patient’s age. Mild symptoms can be treated through medications, physiotherapy, and changes in lifestyle, whereas moderate to severe cases may require surgical intervention. Spondyloarthritis Spondyloarthritis, also referred to as spondyloarthropathy, is a type of rheumatic disease that causes inflammation in various joints. There are two types of spondyloarthritis—axial spondyloarthritis, which causes inflammation of the joints in the chest, spine, and hip bone, and peripheral spondyloarthritis, which causes inflammation in the fingers, knees, and toes.
