Can viruses survive?
Viruses. Viruses are even smaller than bacteria and require living hosts — such as people, plants or animals — to multiply. Otherwise, they can't survive. When a virus enters your body, it invades some of your cells and takes over the cell machinery, redirecting it to produce the virus.
Why are viral infections so difficult to treat?
But the treatment of viral infections has proved more challenging, primarily because viruses are relatively tiny and reproduce inside cells. For some viral diseases, such as herpes simplex virus infections, HIV/AIDS, and influenza, antiviral medications have become available.

Overview
- Influenza, also known as the \"flu\", is a respiratory infection caused by viruses. The flu differs in several ways from the common cold. Symptoms of the flu include body chills, fever, headache, muscle ache and sore throat. Unlike many other viral respiratory infections, the flu can cause severe illness and life-threatening complications in many people. The flu is contracted in the sa…
Treatment
- Many viral infections resolve on their own without treatment. Other times, treatment of viral infections focuses on symptom relief, not fighting the virus. For example, cold medicine helps alleviate the pain and congestion associated with the cold, but it doesn't act directly on the cold virus. There are some medications that work directly on viruses. These are called antiviral medic…
- The best way of treating human viruses will depend on the strength of the individuals immune system, their overall health status, age, the severity of the condition, and the type of viruses involved. Minor illnesses caused by viral infections usually only require symptomatic treatment, while more severe conditions may require advanced medical treatment and sometimes even lif…
- Your surgeon can provide antibiotics and any other therapies that are necessary to prevent the infection from spreading.
- For most viruses, treatment is for the symptoms, such as using over-the-counter pain relievers to ease pain and reduce fever, rest for fatigue, etc., until the virus is gone. But the viruses themselves are not easy to treat. For example, treatment for hepatitis C, a liver disease, involves a strict medication regimen that can take from several weeks up to a few months before the virus is cle…
Signs And Symptoms
- Viral skin infections can range from mild to severe and often produce a rash. Examples of viral skin infections include:
- Viral infections come with a variety of symptoms ranging from mild to severe. Symptoms may vary depending on what part of the body is affected, type of viruses, age, and overall health of the affected person. Children often contract viral infections, as children spend time around other children who have colds, and this makes it more likely that the cold will be passed on to them. A …
- The signs and symptoms of a viral infection depend on what virus you have and how it affects your body. Here are a few examples:Influenza: 1. Fever 2. Muscle ache 3. Cough 4. Sore throat 5. HeadacheMeningitis: 1. Stiff neck 2. Headache 3. Fever 4. Nausea and vomiting 5. Rash 6. Sensitivity to light (photophobia) 7. ConfusionMalaria: 1. Fever 2. Headache 3. Chills 4. Poor app…
- Infections may start almost anywhere. Common places where infections can start include: 1. The mouth 2. The skin 3. The lungs 4. The urinary tract 5. The rectum 6. The genitalsSigns of infection include: 1. A fever, which is a temperature of 100.5°F (38°C) or higher 2. Chills or sweating 3. Sore throat, sores in the mouth, or a toothache 4. Abdominal pain 5. Pain near the anus 6. Pain or bur…
Prevention
- Frequent hand-washing, covering the nose and mouth when coughing or sneezing, and avoiding contact with infected individuals can all reduce the spread of respiratory infections. Disinfecting hard surfaces and not touching the eyes, nose, and mouth can help reduce transmission as well. The best way to avoid viral skin infections is to avoid skin-to-skin contact (especially areas that …

Walking 20 minutes a day, without over-exertion, can help keep the body healthy and get back into optimum shape after a viral infection. The body is resilient and will continue to thrive in the right circumstances. Taking care of the immune system after a virus wil…
- The good news is that prevention of all of these problems can be as simple as washing hands frequently and using hand sanitizer when a sink is not available. Hand washing is the best way to prevent infection, and while there are other tactics that can also reduce risk, keeping hands clean continues to be the best way to stay healthy after surgery.
- Viruses are spread in different ways, depending on the virus. Hepatitis C, a liver disease, is spread through body fluid. On the other hand, influenza can be spread by coming in contact with the virus that has been left behind on an object, like a phone, or through droplets in the air, if someone with the flu sneezes or coughs in front of you. Not all viral infections can be prevented, but you can re…
Definition
- Contagiousness refers to the ability of a virus to be transmitted from one person (or host) to another. Viral infections are contagious for varying periods of time depending on the virus. An incubation period refers to the time between exposure to a virus (or other pathogen) and the emergence of symptoms. The contagious period of a virus is not necessarily the same as the in…
Causes
- A viral infection is a proliferation of a harmful virus inside the body. Viruses cannot reproduce without the assistance of a host. Viruses infect a host by introducing their genetic material into the cells and hijacking the cell's internal machinery to make more virus particles. With an active viral infection, a virus makes copies of itself and bursts the host cell (killing it) to set the newly-f…
Examples
- Respiratory viral infections affect the lungs, nose, and throat. These viruses are most commonly spread by inhaling droplets containing virus particles. Examples include:
- Viruses “hijack” normal, living cells in your body. They use these cells to replicate and multiply, eventually destroying the host cell – this is what makes you sick. Unlike bacterial infections that respond to antibiotics, viral infections are not so easy to treat. Many, like colds, run their course and your body heals on its own, but others, like HIV, do not.Some of the more common viruses i…
Diagnosis
- The diagnosis of a viral infection is usually based on the physical symptoms and the history of the illness. A condition such as influenza, which is caused by a virus, is generally easy to diagnose because most people are familiar with the symptoms. Other types of viral infections may be harder to diagnose and various tests may have to be performed.
Classification
- Both viral and bacterial infections cause sickness; however, there is a difference between them. A viral infection is any type of infection that is caused by a virus, which is even smaller than bacteria and is encapsulated by a protective coating, so it is more difficult to kill than bacteria. Viral infections involve a dormant virus getting into a living cell and re-writing the cell's genetic codes …
Risks
- While an infection in an incision or the urinary tract are the most common infections after having surgery, it is also possible to have pneumonia, a serious lung infection. Surgery patients are at a higher risk than the average person to develop pneumonia, so the development of a cough in the days following the procedure should not be ignored. Likewise, severe diarrhea should not be ign…
