Protect yourself against respiratory syncytial virus with Klintensiv

Respiratory syncytial virus (RSV) is one of the most common causes of severe respiratory infections, especially among young children and the elderly. Although initial symptoms are often similar to a common cold, RSV can rapidly progress into severe forms of bronchiolitis and pneumonia, which require intensive medical treatment. Every year, millions of people face the risks of this virus, and its spread is much more frequent during the cold season.

In this article, we will explain how to identify RSV symptoms, how to prevent its spread, and how to protect your loved ones. You will discover simple yet effective solutions to prevent respiratory infections by using reliable disinfecting products, such as those from the Klintensiv portfolio. Find out what protective measures you should take and how you can create a safer environment, reducing the risks of infections in your family. Do not let respiratory syncytial virus affect your health or that of your loved ones!

What is respiratory syncytial virus (RSV)?

Respiratory syncytial virus (RSV) is a highly contagious respiratory virus from the Paramyxoviridae family, Pneumovirus genus, which primarily affects the lower respiratory tract and is a frequent cause of viral bronchiolitis and pneumonia, especially in young children and the elderly. RSV is responsible for most cases of severe respiratory infections in infants and can lead to hospitalizations, particularly among those with weakened immune systems or pre-existing conditions (***, Clinical Overview of RSV, 2024).

Why is it dangerous?

RSV is most often a seasonal issue, with peak activity in the cold months (autumn and winter). Almost all children contract the virus by the age of 2, but it can also affect adults, especially the elderly or those with low immunity (***, 2023).

RSV is the leading cause of hospitalization for respiratory illnesses in infants, and in the case of the elderly and individuals with chronic respiratory conditions, the virus can worsen existing respiratory problems. (***, Clinical Overview of RSV, 2024).

How is respiratory syncytial virus transmitted?

RSV is transmitted in several ways, which makes prevention even more important (Dias M., 2023):

• Saliva droplets and respiratory secretions: the virus is easily spread into the air when an infected person coughs or sneezes
• Direct contact with an infected person: for example, by shaking hands or kissing
• Through contaminated surfaces: RSV can survive for several hours on surfaces such as toys, phones, doorknobs, or tables (***, 2024), and if a healthy person touches these surfaces and then touches their face (eyes, nose, or mouth), they can become infected.
• Through the placenta, from mother to fetus (***, 2023)

Areas with a high risk of infection include:

• Daycares, kindergartens, and schools, where children come into close contact with other children
• Hospitals and care centers, especially for children, the elderly, or people with chronic conditions
• Crowded public places, such as stores or public transportation

Who is at higher risk of infection?

• Infants under 6 months and children under 2 years: the former have an underdeveloped immune system with only temporary protection from maternal antibodies, and the latter are at high risk of severe complications like bronchiolitis and pneumonia.
• Premature infants: they have underdeveloped lungs and immune systems, putting them at increased risk of severe infection.
• Immunocompromised individuals: people with autoimmune diseases, cancer, or those on immunosuppressive treatments are at major risk of complications.
• Individuals with pre-existing respiratory diseases (asthma, COPD): chronic lung conditions that aggravate the progression of RSV infections.
• The elderly over 65: decreased immune system efficiency and respiratory comorbidities.
• People exposed to cigarette smoke: increases the risk of respiratory infections, including RSV.
• People working in crowded environments (daycares, kindergartens, hospitals): places where RSV spreads easily through direct contact or aerosols.
• Non-exclusively breastfed children: they do not benefit from the immune protection of breast milk, making them more vulnerable.

Symptoms and complications of respiratory syncytial virus infection

Initial symptoms usually appear between 2 and 8 days after exposure to the virus. A person infected with RSV can spread the virus even before they start showing symptoms (1-2 days), and the contagious period may last longer than with other respiratory viruses that cause the flu or common cold. An infected person is most contagious in the first 3-4 days of illness and can continue to transmit the virus for up to 8-10 days after the onset of symptoms. In infants, young children, and people with weakened immune systems, this period can be longer (4 weeks or more). (***, 2024)

Initial symptoms of respiratory syncytial virus are often easily confused with a common cold (***, 2023): dry cough, mild fever, stuffy or runny nose, sneezing, sore throat, headache.

As the infection progresses, severe symptoms can also occur, especially in young children and the elderly (***, 2023): wheezing – a high-pitched sound usually heard during exhalation, rapid breathing or difficulty breathing, severe cough, bluish skin color due to lack of oxygen (cyanosis), extreme fatigue, high and persistent fever.

Infants are the most severely affected by respiratory syncytial virus. In addition to those listed above, lethargy, irritability, and loss of appetite may also occur (***, 2023).

Some cases may require hospitalization, especially in premature infants and those with heart and lung diseases, but most children and adults recover within one or two weeks.

Common complications of respiratory syncytial virus include:

• Bronchiolitis: inflammation of the bronchioles (small airways), which reduces airflow and leads to severe breathing difficulties, being more common in children under 2 years old. As the inflammation progresses, mucus can accumulate in the airways, making breathing even more difficult. It can lead to hospitalization, requiring supplementary oxygen or even intensive care. (***, 2023)

• Viral pneumonia: lung infection that can lead to severe inflammation of the lung tissues. This can result in the accumulation of fluids and mucus, making breathing more difficult and leading to a drop in blood oxygen levels. Hospitalization may be required, needing respiratory support treatments (including oxygen therapy) and, in severe cases, mechanical ventilation. The elderly and those with pre-existing health issues, such as cardiovascular or pulmonary diseases, have an increased risk of developing severe viral pneumonia. (Marcin, 2024)

• Apnea: occurs when airways are blocked by inflammation or mucus, and the body cannot properly respond to oxygen needs. Sometimes it requires immediate medical intervention, including assisted breathing. It can also increase the risk of dehydration, necessitating continuous monitoring in the hospital. (Garzon & Wiles, 2002)

• Bronchial asthma: RSV can alter airway sensitivity and lead to an exaggerated reaction to other environmental factors, such as cigarette smoke, dust, or pollen. This can increase the risk of chronic asthma or worsen symptoms in people who already have asthma. (***, 2024)

• Otitis media: infection of the middle ear, caused by the virus entering the space behind the eardrum, which is more common in infants and young children. It can lead to long-term complications, such as temporary or chronic hearing loss. (Patel, Nguyen, Revai, & Chonmaitree, 2006)

• Sinusitis: inflammation of the mucous membrane lining the cranial sinuses as a result of viral infection. It manifests as severe nasal congestion caused by excessive mucus production. In the event of a secondary infection, antibiotic treatment is necessary, following a doctor's consultation. (***, 2023)

Diagnostic methods for respiratory syncytial virus infection

The diagnosis of RSV infection involves several approaches, depending on the patient's symptoms and medical history.

• Laboratory tests

Respiratory syncytial virus (RSV) infection can be confirmed through several paraclinical methods, including rapid tests, molecular biology techniques, and serological tests (***, 2022).

1. Rapid immunochromatographic tests: allow detection of RSV antigens from respiratory samples, useful for rapid diagnosis, more sensitive in children than in adults.
2. Serological tests: measure IgA antibodies (indicating active infection) and IgG (indicating previous infections or transplacental protection). In infants, IgG may come from maternal protection.
3. Molecular biology techniques:
   • RT-PCR: detects the genetic material of RSV from respiratory samples, highly sensitive, even for mild infections.
   • Multiplex PCR: allows simultaneous detection of multiple pathogens from a single sample.
4. Samples for testing: can be collected from the upper respiratory tract (nasopharyngeal swabs) or lower (bronchoalveolar lavage fluid, endotracheal aspirate, etc.), depending on the severity of the infection.
5. Antigen identification: used for rapid diagnosis, being more efficient in pediatric cases but less sensitive in adults.

Treatment for respiratory syncytial virus

There is no specific treatment for respiratory syncytial virus infection, so treatment is supportive only. In most cases, the patient recovers within 1-2 weeks.

Antipyretic medications such as paracetamol or ibuprofen can be administered to reduce fever and relieve pain. Aspirin is contraindicated for children under 16 due to the risk of Reye's syndrome (a rare and severe condition that primarily affects the brain and liver). Saline solutions can be used to clear the nose and reduce congestion. Fluid intake is essential to prevent dehydration, especially in infants and young children. Signs of dehydration in them include dry mouth and tongue, lack of tears, lethargy, and dry diapers for eight hours or more. (Dias M., 2023)

Severe signs such as difficulty breathing, persistent fever, or significant dehydration require hospitalization, and treatments may include oxygen therapy, mechanical ventilation, suctioning of pulmonary secretions, intravenous fluids, or antiviral medication. (Dias M., 2023)

How to maintain long-term respiratory health

To prevent long-term complications, follow these recommendations:

• Avoid passive smoking, which can worsen existing respiratory conditions and increase the risk of infections.
• Monitor recurring symptoms and consult a doctor if you notice signs of asthma or chronic breathing difficulties.
• Maintain a clean environment in your home by using cleaning and disinfecting products that reduce the risks of infection.

Effective prevention measures

To prevent the spread of RSV, it is essential to adopt rigorous hygiene measures, especially during the cold season when respiratory syncytial virus is more active. Here are some recommendations:

• Proper hand hygiene: Proper and frequent handwashing with soap for at least 20 seconds is essential to prevent the spread of the virus. If you do not have access to water, use alcohol-based sanitizing products. Klintensiv disinfecting products are quick and effective protection solutions.
• Surface disinfection: Frequently touched surfaces, such as tables, mobile phones, toys, and doorknobs, must be cleaned and disinfected daily.
• Isolation of infected persons: People with RSV should stay home and avoid contact with others, especially in the first days of illness when they are most contagious.
• Avoid crowds and contact with sick people: social distancing and avoiding crowded places are important, especially during the cold season.
• Wearing a protective mask in crowded areas and around sick people.
• Covering mouth and nose: When you cough or sneeze, cover your mouth and nose with a tissue or your arm to prevent the spread of droplets.
• Educating children about proper hygiene is essential: Make sure little ones learn to wash their hands and not share toys with other children who show symptoms.
• Frequent ventilation of enclosed spaces: ensure your home or office is well-ventilated.
• Vaccination: in certain cases, RSV vaccination is recommended for people at high risk.

The EMA has authorized the marketing in the European Union of the Abrysvo vaccine, indicated for immunization against diseases caused by respiratory syncytial virus. It is the first RSV vaccine indicated for the passive immunization of infants from birth to 6 months, after the mother has been administered the vaccine during pregnancy. It is also indicated for the active immunization of adults aged 60 and older. (EMA, 2024)

Another vaccine, Arexvy, is indicated for active immunization for the prevention of lower respiratory tract disease caused by respiratory syncytial virus in adults 60 years of age and older. It may also be used in adults 50 to 59 years of age who are at increased risk for the disease. (EMA, 2024)
