Key Insights into Influenza B Virus: What You Need to Know
This article provides essential information about Influenza B, including its transmission, symptoms, and high-risk groups. It highlights the importance of early detection and preventive measures to avoid severe health complications caused by this contagious virus, especially during flu seasons. Understanding these aspects helps in better management and timely treatment to reduce risks.
Influenza, commonly known as the flu, affects the respiratory tract and is caused by different strains of flu viruses. Among them, Influenza B is notable for its impact and transmission. Similar in symptoms to Influenza A, type B can cause significant health issues if untreated. Understanding its causes, symptoms, and risk factors is vital for prevention and management.
How Influenza B Spreads
This highly contagious virus is mainly transmitted through respiratory droplets expelled during coughing or sneezing. It can also spread via inhalation of aerosols containing the virus, which can travel up to six feet from an infected person. Flare-ups are common during colder months.
Symptoms of Influenza B
Infection with influenza B affects both respiratory and gastrointestinal systems. Typical signs include fever, chills, sore throat, coughing, nasal congestion, sneezing, fatigue, muscle pain, and body aches. Symptoms resemble those of a common cold but can escalate quickly. Patients often experience congestion, sore throat, and sometimes high fever up to 106°F. Additional symptoms may include nausea, abdominal pain, loss of appetite, weakness, and chills.
Individuals with asthma should seek prompt treatment since influenza B can trigger severe asthma attacks. If untreated, complications such as pneumonia, heart inflammation, kidney failure, and respiratory failure can develop, posing serious health risks.
Who Is Most at Risk?
Children aged 2 to 5 and seniors over 65 are more vulnerable to Influenza B. Residents of long-term care facilities or nursing homes are also at increased risk due to limited fresh air circulation. Other risk factors include weakened immune systems, obesity, and chronic conditions like diabetes, heart disease, asthma, liver, or kidney issues. Pregnant women and postpartum women within two weeks after delivery are also highly susceptible.
