Viral diseases are infections caused by viruses, which are a type of microorganism. Viruses come in a variety of shapes and sizes, and they cause a wide range of diseases.
The common cold, which is caused by a viral infection of the upper respiratory tract, is the most common type of viral disease (nose and throat). Other viral diseases that are common include:
- Flu (influenza)
- Human immunodeficiency virus (HIV/AIDS)
- Human papillomavirus (HPV)
- Infectious mononucleosis
- Viral hepatitis
- Viral meningitis
The varicella-zoster virus is responsible for chickenpox. It causes a rash with small, fluid-filled blisters that is itchy. People who have never had chickenpox or who have not been vaccinated against it are highly contagious.
Children can now be protected against chickenpox with the use of a vaccine. The chickenpox vaccine protects against chickenpox and its complications safely and effectively.
Influenza is a virus that attacks the respiratory system, including the nose, throat, and lungs. Despite the fact that influenza is commonly referred to as "the flu," it is not the same as stomach "flu" viruses, which cause diarrhea and vomiting.
The virus spreads through the air in droplets when someone with influenza coughs, sneezes, or talks. You can either inhale the droplets directly or pick up germs from an object (such as a phone or computer keyboard) and then transfer them to your eyes, nose, or mouth.
Infection with the herpes simplex virus causes herpes (HSV). It causes mouth sores or blisters, as well as other symptoms, in or around the mouth or genitals.
HSV is divided into two types:
- Oral herpes is caused by HSV-1, and it usually affects the mouth and surrounding skin.
- HSV-2 is the virus that causes genital herpes, which is usually spread through sexual contact.
HSV can easily spread from person to person if it is present on the skin and comes into contact with the moist skin of the mouth and genitals, including the anus. The virus can also be spread by coming into contact with other parts of the body, such as the eyes and skin.
By touching an object or a surface, such as a washbasin or a towel, a person cannot contract HSV.
AIDS, or acquired immunodeficiency syndrome, is a chronic, potentially fatal disease caused by the human immunodeficiency virus (HIV) (HIV).
By destroying your immune system, HIV weakens your body's ability to fight infection and disease.HIV is a sexually transmitted infection that affects both men and women (STI). It can also be passed from mother to child during pregnancy, childbirth, or breastfeeding through contact with infected blood.
It could take years without medication for HIV to weaken your immune system to the point where you develop AIDS.
5. Human papillomavirus
The human papillomavirus (HPV) is a virus that is transmitted from one person to another through skin-to-skin contact.HPV is a virus that can affect your genitals, mouth, or throat.
There are over 100 different types of HPV, with more than Trusted Source of them being transmitted through sexual contact. Skin-to-skin contact is how HPV infection spreads from person to person.
The majority of people contract genital HPV through direct sexual contact, which includes vaginal, anal, and oral sex. Intercourse isn't required for HPV transmission because it's a skin-to-skin infection.
Shingle is a painful rash caused by a viral infection. Although shingles can appear anywhere on your body, the most common symptom is a single stripe of blisters wrapping around your torso on either the left or right side.
The varicella-zoster virus causes shingles, which is the same virus that causes chickenpox. The virus remains inactive in nerve tissue near your spinal cord and brain after you've had chickenpox.
7. Viral Meningitis
The fluid and membranes (meninges) that surround your brain and spinal cord become inflamed with meningitis. Meningitis causes swelling in the brain and spinal cord, resulting in headaches, fever, and stiff neck as symptoms.
Virus-induced meningitis is usually mild and self-resolving. Enteroviruses, which are most common in the late summer and early fall, cause the majority of cases in the United States. Viruses like herpes simplex, HIV, mumps, West Nile virus, and others can cause viral meningitis.
8. Viral Hepatitis
Hepatitis caused by a viral infection causes inflammation and damage to the liver. Inflammation is the swelling that occurs when the body's tissues are damaged or infected. Organs can be damaged by inflammation. Hepatitis A, B, C, D, and E are viruses that cause hepatitis.
Hepatitis A and E are transmitted through contact with food or water contaminated by the stool of an infected person. Hepatitis E can also be contracted by eating raw pork, deer, or shellfish. Hepatitis B, C, and D are transmitted through blood contact with an infected person.
Hepatitis B and D can also be transmitted through bodily fluids.
Mumps is a viral infection that mostly affects the saliva-producing (salivary) glands near your ears. One or both of these glands may swell as a result of mumps.
Mumps is caused by a virus that can easily spread from one person to another via infected saliva. Mumps can be contracted if you are not immune by inhaling saliva droplets from an infected person who has just sneezed or coughed. Mumps can also be spread by sharing utensils or cups with someone who is infected.
Measles is a viral infection that affects children. Measles, which was once quite common, can now almost always be prevented with a vaccine. Measles is a highly contagious disease caused by a virus that replicates in the nose and throat of an infected child or adult.
When a person with measles coughs, sneezes, or speaks, infected droplets spray into the air, where they can be inhaled by others. Infected droplets can also land on a surface and remain contagious and active for several hours.
After touching an infected surface, you can contract the virus by putting your fingers in your mouth or nose, or rubbing your eyes.
Rubella is a contagious viral infection characterized by a characteristic red rash. It's also known as three-day measles. While most people will experience only minor symptoms or none at all, it can have serious consequences for unborn children whose mothers become infected during pregnancy.
Rubella is caused by a virus that can be transmitted from one person to another. It can also be transmitted through the bloodstream from pregnant women to their unborn children.
12. Infectious Mononucleosis
It is also known as the kissing disease. The Epstein-Barr virus, which causes mono, is spread through saliva.
Mono can be contracted by kissing an infected person, but it can also be contracted by sharing a glass or food utensils with an infected person. Mononucleosis, on the other hand, isn't as contagious as some infections, like the common cold.
The Epstein-Barr virus is the most common cause of mononucleosis, but other viruses can also cause similar symptoms. This virus is spread through saliva and can be contracted through kissing or sharing food or beverages.
