How are viral and bacterial diseases treated?
Infection Treatment Medicine An infection is caused by the over-growth of a micro-organism somewhere in the body. Micro-organisms include bacteria, viruses and fungi amongst others. Bacterial infections are treated with antibiotics such as amoxicillin, erythromycin and ciprofloxacin.
Why are bacteria and viruses treated differently?
While bacteria and viruses can both cause mild to serious infections, they are different from each other. 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 is the difference between viral and bacterial?
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.Apr 20, 2020
What is the treatment for bacteria?
Antibiotics are the usual treatment. When you take antibiotics, follow the directions carefully. Each time you take antibiotics, you increase the chances that bacteria in your body will learn to resist them causing antibiotic resistance. Later, you could get or spread an infection that those antibiotics cannot cure.
How are viruses treated?
For most viral infections, treatments can only help with symptoms while you wait for your immune system to fight off the virus. Antibiotics do not work for viral infections. There are antiviral medicines to treat some viral infections. Vaccines can help prevent you from getting many viral diseases.Mar 10, 2022
What are 3 differences between viruses and bacteria?
Viruses are tinier: the largest of them are smaller than the smallest bacteria. 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.Apr 17, 2021
Can viral infections be treated with antibiotics?
Antibiotics DO NOT work on viruses, such as those that cause colds, flu, or COVID-19. Antibiotics also are not needed for many sinus infections and some ear infections. When antibiotics aren't needed, they won't help you, and the side effects could still cause harm.

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.
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.
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.
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.
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.
How long do chronic infections last?
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 tests are performed to diagnose bacterial infection?
Tests that are frequently performed to help us with the diagnosis of a bacterial infection include a complete blood count and cultures of fluid that we are concerned about. This may include a blood culture, urine culture, or spinal culture (which requires a spin al tap).
How long does a viral infection last?
Of note, when compared to adults, upper respiratory infections in children may last longer (up to 14 days) ...
How to tell if a child has a virus?
Whether the infection turns out to be caused by virus or bacteria, you should watch your child for any of the following signs and bring them to medical attention if they develop: 1 Dehydration, demonstrated by decreased fluid intake; urination less than three times in 24 hours; or decreased tears with crying 2 Increased work of breathing including fast breathing, nostril flaring, use of rib, stomach, or neck muscles to breathe 3 Markedly decreased activity or responsiveness 4 No improvement over a three - to five-day period 5 All children under three months of age with a fever
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.
What is the difference between a virus and a bacterium?
A virus is a miniscule pocket of protein that contains genetic material. If you placed a virus next to a bacterium, the virus would be dwarfed . For example, the polio virus is around 50 times smaller than a Streptococci bacterium, which itself is only 0.003mm long.
What are the different types of bacteria?
Bacteria types. Bacteria that cause disease are broadly classified according to their shape. The four main groups include: Bacilli – shaped like a rod with a length of around 0.03mm. Illnesses such as typhoid and cystitis are caused by bacilli strains. Cocci – shaped like a sphere with a diameter of around 0.001mm.
What are some examples of cocci?
Depending on the sort, cocci bacteria group themselves in a range of ways, such as in pairs, long lines or tight clusters. Examples include Staphylococci (which cause a host of infections including boils) and Gonococci (which cause the sexually transmissible infection gonorrhoea).
How do viruses spread?
Viruses are spread from one person to another by: Bacteria types. Characteristics of the bacterium. Curing a bacterial infection. Virus types. The body’s response to viral infection. Curing a viral infection. Immunisation against viral infection is not always possible. Where to get help.
What is the name of the bacteria that causes cholera?
Vibrio – shaped like a comma. The tropical disease cholera, characterised by severe diarrhoea and dehydration, is caused by the vibrio bacteria.
Why are antibiotics useless?
Antibiotics are useless against viral infections. This is because viruses are so simple that they use their host cells to perform their activities for them. So antiviral drugs work differently to antibiotics, by interfering with the viral enzymes instead.
What are the causes of human infections?
Many human infections are caused by either bacteria or viruses. Bacteria are tiny single-celled organisms, thought by some researchers to be related to plants. They are among the most successful life forms on the planet, and range in habitat from ice slopes to deserts.
