Most importantly, bacterial and viral infections, can cause mild, moderate, and severe diseases. Throughout history, millions of people have died of diseases such as bubonic plague or the Black Death, which is caused by Yersinia pestis bacteria, and smallpox, which is caused by the variola virus.
How are bacterial and viral diseases cured treated?
Serious infections can be treated with antibiotics, which work by disrupting the bacterium's metabolic processes, although antibiotic-resistant strains are starting to emerge. Immunisation is available to prevent many important bacterial diseases such as Hemophilus influenza Type b (Hib), tetanus and whooping cough..
How are viral diseases and bacterial diseases treated prevented?
Since the beginning of the 20th century, vaccines have been developed. Vaccines have drastically reduced the number of new cases of viral diseases such as polio, measles, and chickenpox. In addition, vaccines can prevent such infections such as the flu, hepatitis A, hepatitis B, human papillomavirus (HPV), and others.
What are the cures and treatment for different diseases caused by bacteria and viruses?
If bacteria cause a disease, treatment with antibiotics usually kills the bacteria and ends the infection. Viral infections are usually treated with supportive therapies, like rest and increased fluid intake. Sometimes people benefit from antiviral medications like oseltamivir phosphate (Tamiflu®).

Practicing good hygiene habits, avoiding the sharing of personal items, and avoiding close contact with people who have active lesions can reduce your risk of developing a cutaneous viral disease.
What is a virus made of?
Viruses are very small infectious agents. They’re made up of a piece of genetic material, such as DNA or RNA, that’s enclosed in a coat of protein. Viruses invade cells in your body and use components of those cells to help them multiply. This process often damages or destroys infected cells.
How are exanthematous viruses transmitted?
Many exanthematous viruses are spread through respiratory droplets from the cough or sneeze of someone with the virus. Other exanthematous viral diseases, such as chickenpox and smallpox, can be transmitted by coming into contact with fluid in broken skin lesions.
What is the best treatment for exanthematous viral disease?
Treating exanthematous viral diseases focuses on managing symptoms. Fever-reducing medications, such as acetaminophen, can help with some of the more bothersome symptoms. Antiviral drugs, such as acyclovir, may be given for chickenpox or shingles.

What causes a virus to spread?
Viral diseases are mainly caused when a virus enters the human body and uses the host machinery to reproduce. If the body’s immune system fails to fight against viruses, it multiplies and spreads to other cells causing infections.
Do viruses infect plants?
Viruses also infect plants. Let us have an overview of the different types of viral diseases, their causes, symptoms and prevention methods. Also Read: Bacterial Diseases.
How to treat viral infections?
Another way of treating viral infections is the use of antiviral drugs. These drugs often have limited success in curing viral disease, but in many cases, they have been used to control and reduce symptoms for a wide variety of viral diseases.
How do we control viral disease?
While we do have limited numbers of effective antiviral drugs, such as those used to treat HIV and influenza, the primary method of controlling viral disease is by vaccination, which is intended to prevent outbreaks by building immunity to a virus or virus family (Figure 21.3. 1 ).
What antiviral drug is used to treat a variety of viral infections?
Other antiviral drugs, such as Ribavirin, have been used to treat a variety of viral infections, although its mechanism of action against certain viruses remains unclear. Figure 21.3. 3: (a) Tamiflu inhibits a viral enzyme called neuraminidase (NA) found in the influenza viral envelope.
How does Tamiflu work?
Tamiflu works by inhibiting an enzyme (viral neuraminidase) that allows new virions to leave their infected cells. Thus, Tamiflu inhibits the spread of virus from infected to uninfected cells.
What is the third use of viruses in medicine?
A third use of viruses in medicine relies on their specificity and involves using bacteriophages in the treatment of bacterial infections. Bacterial diseases have been treated with antibiotics since the 1940s. However, over time, many bacteria have developed resistance to antibiotics.

Antivirals have been developed to treat genital herpes (herpes simplex II) and influenza. For genital herpes, drugs such as acyclovir can reduce the number and duration of episodes of active viral disease, during which patients develop viral lesions in their skin cells.
What is gene therapy?
Gene therapy is used to treat genetic diseases such as severe combined immunodeficiency (SCID), a heritable, recessive disease in which children are born with severely compromised immune systems. One common type of SCID is due to the lack of an enzyme, adenosine deaminase (ADA), which breaks down purine bases.
How to diagnose a viral infection?
In order to diagnose a bacterial or viral infection, a doctor will ask a person about their medical history and symptoms. The doctor may then order tests to look for signs of bacteria or viruses in the person’s blood or urine, or from a throat or nasal swab.
How to prevent infection?
However, some infections are untreatable. The best way to prevent infection is to practice good hygiene. Vaccines are an effective method for preventing certain viruses, such as measles, mumps, and polio. A person should visit their doctor if they suspect they may have an infection.
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.
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 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.
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.
What are the different forms of antibiotics?
Antibiotics are available in the following forms: oral forms, such as pills, capsules, and liquids. ear drops and eye drops. topical forms, such as creams, ointments, and sprays. If the infection is more severe, a doctor may recommend an antibiotic injection or intravenous infusion or drip.
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.
Can bacteria cause a person to die?
Most bacteria cause no harm to people, but there are exceptions. Infections caused by bacteria include: Strep throat. Tuberculosis. Urinary tract infections. Inappropriate use of antibiotics has helped create bacterial diseases that are resistant to treatment with different types of antibiotic medications.
