Viral Infection Symptoms In Toddler


The deep socio-economic changes, taking place in different countries, lead not only to changes in the quality of life, but also cause adverse trends in the growing number of diseases. This makes the assessment of the viral infections incidence particularly important.

Despite the undoubted achievements in the fight against infectious diseases, their importance in the overall incidence structure does not only decrease, but also shows an increasing trend, according to various estimates. Due to this, the timely diagnosis and detection of viral infection symptoms play a special role.

Microscopic organisms evolve with the development of humanity and expand the number of diseases. New methods for the treatment and prevention of diseases do not reduce the number of affected persons in developed and developing countries (such as USA, India, Australia, Canada and the UK).

The viral infection symptoms can vary depending on the type of infection, duration of infection, age of people, and many other factors. This review will address some of the most common viral infections symptoms.

Viral hepatitis

This disease is characterized by hepatic inflammation and can have acute or chronic forms. Viral hepatitis is a common intestinal infection with fecal-oral mechanism of transmission. The causes of infection are eating a variety of foods, not exposed to heat treatment, drinking raw water, and dirty hands.

Children or toddlers are most commonly infected with viral hepatitis. This viral infection symptoms are fever, dizziness, muscle aches, fatigue, decreased appetite, nausea, vomiting and frequent bowel movements.

One of the first viral hepatitis symptoms is fever, which often persists within 1-2 days. Rare disease signs are low blood pressure and tachycardia.

HIV infection

The disease progresses slowly, affecting the cells of the immune system and causing the body loose its ability of defending itself against microorganisms. HIV infection can significantly reduce the life expectancy of the patient, so timely detection of the viral infection symptoms is essential.

Adults and especially older people have an increased risk of rapid disease progression. Obvious viral infection symptoms are rash, fever, swollen lymph nodes and weight loss. Less commonly observed are nausea, diarrhea and enlargement of the liver or spleen.

The second phase of HIV infection is called asymptomatic and may last for several years. During this time, people lead normal lifestyle and feel well, so the efforts of many international medical organizations are aimed at identifying the first symptoms.

Influenza virus infection

Influenza is an acute infectious disease that spreads around the world in the form of an annual outbreak. Influenza agent is characterized by unusual volatility, adaptability and the formation of totally new strains.

Influenza is a disease with a short incubation period. Its common viral infection symptoms are sore throat, lethargy, drowsiness, muscle weakness, low blood pressure, chills, fever, headache and cough.

Diagnosis of the flu is not difficult, and domiciliary treatment is usually enough for fighting it. However, hospitalization may be required in severe influenza symptoms, such as high fever, combined with high temperature, frequent vomiting and meningeal syndrome.

Herpes virus infections

This is a group of widespread infections, which are often characterized by the ability of pathogens to the life-long survival in human bodies. Viruses can stay in the patient’s body for a long time without the active reproduction, metabolism, and symptoms onset.

Herpesviruses are combined into the vast Herpesviridae family, consisting of more than 100 representatives. Only 8 of them are pathogens for humans. They are divided into three subfamilies, depending on the type of genome, immunological characteristics and cells they affect.

Herpes viral infection symptoms can vary, depending on many factors. Common signs are irritability, problematic food intake, lesions of mouth mucosa, genital tract, skin, and nervous system.

Other types of viral infections

There are many types of viral infections, which often cause diseases. These may include polio, infectious mononucleosis, measles, rubella, smallpox, tick-borne encephalitis, and many others.

Viral infection symptoms and bacterial infection symptoms can be similar, so it is first necessary to identify the type of the protozoa and then prescribe treatment. Duration of treatment with antiviral drugs depends on the severity of symptoms, forms of the disease, age, affected cells or tissues.

What is a Viral Infection?

A virus is a tiny organism that causes an infection in the body. Viruses are made up of the genetic material known as DNA or RNA, which the virus uses to replicate. In order for a virus to survive, it must invade and attach itself to a living cell. It will then multiply and produce more virus particles.

By attaching itself to a host cell, the virus may either kill or alter the cell’s functions. When the cell dies, new types of viruses are released, and they infect other cells. This is how viruses cause disease. Generally, viruses will only infect one type of cell. For example, the cold virus will only infect cells of the upper respiratory tract.

Viruses can be transmitted in numerous ways, such as through contact with an infected person, swallowing, inhalation, or unsafe sex. Factors such as poor hygiene and eating habits can increase your risk of contracting a viral infection.

The external barriers, such as the skin and mucous membranes, are the first line of defense. The body’s immune defenses are triggered when the virus enters the body, and white blood cells (lymphocytes and monocytes) begin to attack and destroy the virus.

This type of general protection is referred to as innate or natural immunity.

Types of Viral Infections

Viruses can affect any part of the body or body system, and can cause infections such as the common cold, flu, gastroenteritis, chicken pox or herpes. The most common type of viral infections involves the respiratory tract.

The common cold is a frequently occurring viral infection and usually includes symptoms such as sneezing, stuffy nose, sore throat and coughing. Although colds are a minor infection of the nose and throat, a cold can last from two days to two weeks. Colds are highly contagious and are spread by fluids from sneezing or coughing, which contain the infection.

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 same airborne manner as the common cold. For both cold and flu, the viruses are easily transmitted in highly populated areas.

The gastrointestinal system is also commonly affected by viruses with symptoms such as diarrhea and/or vomiting. Stomach viruses can be spread through contaminated food or water and can cause viral gastroenteritis, meaning inflammation of the stomach and intestines (small and large). Improper hand washing following a bowel movement or handling a diaper can spread the disease from person to person. Symptoms of gastroenteritis can include nausea with or without vomiting, diarrhea, low-grade fever and abdominal pain. Many people call gastroenteritis the “stomach flu”, although this virus is not a strain of Influenza at all.

The skin can also be infected by a viral infection such as the common wart or chicken pox. Chickenpox is an infectious disease; with most cases occurring in children under age 15, but older children and adults can also get it. It spreads very easily by human contact. Symptoms include itchy rash, fever and headache. The rash is blister-like and usually appears on the face, scalp or torso. The disease is usually mild and lasts 5 to 10 days, although adults and older children tend to get sicker from it. Chickenpox in a virus that stays in the body forever and in most cases a person who has had the virus will likely never contract it again.

Viruses such as herpes are caused by the herpes simplex virus (HSV). This infection can infect the mouth, genitals and anus. Oral herpes causes sores around the mouth and face, while genital herpes affects the genitals, buttocks and anus. Genital herpes is known as a sexually transmitted disease (STD) and it is transmitted through sexual contact through the mouth and genitals. This virus can be spread even when sores aren’t present. Like chickenpox, this virus will remain in the body forever; however, a person with herpes may continue to deal with reoccurrences or “outbreaks” for life.

Diagnosing Viral Infections

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.

Various Diagnostic Tests for Viral Infections

  • Blood tests to check for antibodies to viruses, or for the antigens themselves
  • Cultures for samples of blood, bodily fluid, or other material taken from the infected area
  • Spinal tap to examine the cerebrospinal fluid
  • Polymerase chain reaction (PCR) techniques may be used to make many copies of the viral genetic material, enabling doctors to rapidly and accurately identify the virus
  • Magnetic resonance imaging (MRI) can detect increased swelling in the temporal lobes

Symptoms of Viral Infections

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.

These symptoms can include:

  • Fever
  • Muscle aches
  • Coughing
  • Sneezing
  • Runny nose
  • Headache
  • Chills
  • Diarrhea
  • Vomiting
  • Rash
  • Weakness

More severe symptoms include:

  • Personality changes
  • Neck stiffness
  • Dehydration
  • Seizures
  • Paralysis of the limbs
  • Confusion
  • Back pain
  • Loss of sensation
  • Impaired bladder and bowel function
  • Sleepiness that can progress into a coma or death

Viral Infection vs. Bacterial Infection

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 with its own. Viruses are not living organisms and need a “living” host in order to reproduce-otherwise it cannot survive. Commonly, viral infections involve the nose, throat and upper airways. Viral infections cause illnesses as minor as the common cold and as severe as AIDS.

To contract a bacterial infection, pathogenic bacterium must gain access into the body through contaminated water, cuts, or contact with an infected person or contaminated objects. One of the major differences between viral and bacterial infections is that a bacterial infection can be transmitted through inanimate objects such as door knobs and countertops, whereas viral cannot. Another difference is that bacteria is a living microorganism and reproduces by dividing itself, while a virus will die if it does not have a host. Common bacterial infections occur due to the invasion of pathogenic bacteria through the respiratory or digestive tract. Some bacterial infections are contagious like strep throat, while others are not.

What Causes Viral Infections?

Human cells are vulnerable to viruses, and when the body is exposed to viral particles, the immune system will try to destroy these particles and eliminate them from the system.

A lowered immune system allows the virus to more easily attach itself to available cells, often bringing about general symptoms such as fever, chills, and muscle aches. This also makes it easier for the virus to replicate, and thus advances symptoms until the immune system can fight the virus off.

Viral Infections in Children

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 child’s immune system is not as strong as adults, and their body is still learning how to fight viruses for the first time. Some infections can become quite serious while some just bring about a feeling of unwell. Often children develop fevers, headaches, runny nose, cough, sore throat and fatigue. These symptoms are caused by the battle between the virus and the body’s immune system.

  • It is important to allow babies and children to rest when they have a fever.
  • For younger children who cannot blow their nose, use a rubber suction bulb to suck drainage from both sides of the nose.
  • Loosen dried nasal drainage with warm water.
  • Children older than four years of age may be able to suck on throat lozenges for sore throats.
  • Children should drink extra water, fruit juices, or soups- avoid giving milk to infants for congestion reasons.
  • Use hot steam to loosen mucus in child’s chest and nasal passages.

Help for Viral Infections

The best way of treating human viruses will depend on the strength of the individual’s 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 life-long treatment. A combination of treatment options such as conventional medicine, complementary therapy, and natural medicine can help to fight the infection, control the symptoms, and strengthen the immune response.

It is important to remember that treating human viruses cannot be accomplished through antibiotics, and the unnecessary use of antibiotics can weaken the immune system, thus increasing the likelihood of contracting another infection.

After Effects of Viral Infection

Viral infections can last as long as two weeks, and after infection, it is important to get the immune system back on track. Eat foods rich in vitamins like oranges, carrots, kiwis, raisins, green beans and strawberries. Continue to drink plenty of fluids, and go easy on sweets, as they make the body acidic and pathogens thrive in this environment.

Start an exercise regimen, like walking, biking with the family or swimming. Take it easy on the body at first and allow breaks. 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 will not only allow for prime health but will help keep new viruses at bay.
