How to treat viral infection?
The treatment of viral infections can include: 1 managing symptoms, such as honey for coughs and warm fluids like chicken soup for oral hydration 2 paracetamol to relieve fever 3 stopping viral reproduction using antiviral medicines, such as medicines for HIV/AIDS and cold sores 4 preventing infection in the first place, such as vaccines for flu and hepatitis
Why are viruses and bacteria different?
This is important to understand, because bacterial and viral infections must be treated differently. Misusing antibiotics to treat viral infections contributes to the problem of antibiotic resistance.
What are some examples of bacterial infections?
Examples of bacterial infections include whooping cough, strep throat, ear infection and urinary tract infection (UTI). Viral infections include the common cold, flu, most coughs and bronchitis, chickenpox and HIV/AIDS. It can be difficult to know what causes an infection, because viral and bacterial infections can cause similar symptoms.
What is the difference between a virus and a bacterium?
Bacteria and viruses are too tiny to be seen by the naked eye, can cause similar symptoms and are often spread in the same way, but that’s where the similarities end. A bacterium is a single, but complex, cell.
Can antibiotics kill bacteria?
Doctors usually treat bacterial infections with antibiotics. They either kill bacteria or stop them multiplying. But since antibiotic resistance is a growing problem, antibiotics may be prescribed only for serious bacterial infections.
Can bacteria survive on their own?
It can survive on its own, inside or outside the body. Most bacteria aren’t harmful. In fact, we have many bacteria on and inside our body, especially in the gut to help digest food. Viruses are smaller and are not cells. Unlike bacteria, they need a host such as a human or animal to multiply.
Bacteria
Bacteria are single-celled microorganisms that thrive in many different types of environments. Some varieties live in extremes of cold or heat. Others make their home in people's intestines, where they help digest food. Most bacteria cause no harm to people, but there are exceptions.
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.
What is the difference between a viral infection and a bacterial infection?
What's the difference between a bacterial infection and a viral infection? As you might think, bacterial infections are caused by bacteria, and viral infections are caused by viruses. Perhaps the most important distinction between bacteria and viruses is that antibiotic drugs usually kill bacteria, but they aren't effective against viruses.

How often do upper respiratory infections occur?
Of note, when compared to adults, upper respiratory infections in children may last longer (up to 14 days) and occur more frequently (average six to eight per year). Influenza is a viral illness that can cause many of the same symptoms but also is frequently accompanied by intense body aches and higher fever.
How long does a virus last?
Symptoms persist longer than the expected 10-14 days a virus tends to last. Sinusitis, ear infections, and pneumonias are common examples of secondary infections. For example, a runny nose that persists beyond 10-14 days may be a sinus infection that would be best treated with an antibiotic.
What is a runny nose?
For example, a runny nose that persists beyond 10-14 days may be a sinus infection that would be best treated with an antibiotic. Ear pain and new onset fever after several days of a runny nose is probably an ear infection.
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.
What are the symptoms of a viral infection?
Bacterial and viral infections can cause similar symptoms such as coughing and sneezing, fever, inflammation, vomiting, diarrhea, fatigue, and cramping -- all of which are ways the immune system tries to rid the body of infectious organisms. But bacterial and viral infections are dissimilar in many other important respects, ...
What are the causes of acute infection?
Coughing and sneezing. Contact with infected people, especially through kissing and sex. Contact with contaminated surfaces, food, and water. Contact with infected creatures, including pets, livestock, and insects such as fleas and ticks. Microbes can also cause: Acute infections, which are short-lived.
Why are antibiotics important?
The discovery of antibiotics for bacterial infections is considered one of the most important breakthroughs in medical history. Unfortunately, bacteria are very adaptable, and the overuse of antibiotics has made many of them resistant to antibiotics. This has created serious problems, especially in hospital settings.
What are the two types of infections?
Bacterial and Viral Infections. Bacterial and viral infections have many things in common. Both types of infections are caused by microbes -- bacteria and viruses, respectively -- and spread by things such as: Coughing and sneezing. Contact with infected people, especially through kissing and sex.

Chronic infections, which can last for weeks, months, or a lifetime. Latent infections, which may not cause symptoms at first but can reactivate over a period of months and years. Most importantly, bacterial and viral infections, can cause mild, moderate, and severe diseases.
Do viruses have a host?
All they have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells.
What are the different types of bacteria?
Some types of infectious bacteria are E. coli, Streptococcus, and Staphylococcus. Contrary to popular opinion bacteria are not all bad. Actually less than 1-percent of bacteria cause illness says the National Institute for Health.
How do viruses affect the host?
Viruses attach to the host’s cells and force the cells to reproduce the virus and can damage or kill the cells. Think of viruses as tiny hijackers that take over the host’s cells making it do whatever the virus wants.
Can antibiotics be used for a viral infection?
A viral infection is treated very differently than a bacterial infection. Antibiotics are worthless against viruses and therefore aren’t used . Often times your doctor will recommend only using medication to help lessen the symptoms of a viral infection, like ibuprofen for a fever, and let your immune system do the heavy lifting by fighting the virus.
Can a virus cause a cold?
Here’s where it gets tricky with bacteria and viruses. The symptoms for both germs can cause almost identical symptoms. A cold caused by a virus can cause a cough, runny nose, and fever in the exact same way that a cold caused by a bacterial infection can. This makes it nearly impossible to determine the cause of your infection based solely on symptoms.
Why is it important to take antibiotics?
Antibiotics are the typical treatment for bacterial infections. When your doctor prescribes you antibiotics it’s important to take the entire prescribed amount and not to stop just because you feel better. Antibiotic resistance is on the rise. With more and more antibiotic usage, bacteria are becoming resistant to certain antibiotics. This is causing super infections that require stronger antibiotics and are much harder to kill.

What are the different types of microorganisms?
Bacteria, viruses, and fungi are different types of microorganisms. Pathogens are microorganisms that have the potential to cause illness or disease. Bacterial pathogens cause bacterial infections, whereas viral pathogens cause viral infections. Sometimes, both bacteria and viruses can cause illness. Examples include pneumonia and meningitis.
How many types of staph are there?
There are more than 30 types of Staphylococcus, or staph, bacteria. Most staph infections are due to the species Staphylococcus aureus (S. aureus). This bacteria lives on the skin or inside the nose and can enter the body through an open wound.
Where does group B strep live?
Group B strep. Group B strep, such as Streptococcus agalactiae usually live harmlessly inside the digestive system and female genital tract. Group B strep most commonly affects newborns. This is because the bacteria can pass from mother to fetus in the womb.
What are the benefits of bacteria?
helping people to digest food. providing vitamins. getting rid of cells that could cause disease. Less than 1% of bacterial species can cause bacterial infections. Such infections occur when the bacteria enter the body and invade the body’s immune system, where they quickly multiply and produce harmful toxins.
How does a virus replicate?
In order to replicate, they must enter the cells of a living organism, such as a human or an animal. A viral infection happens when a virus gets into the body and invades healthy cells. The virus then uses the cell’s machinery to make copies of itself. This process can kill, damage, or change the cells.
