Why are respiratory infections surging now?
Respiratory infections are increasing this season due to mutations in viruses like adenovirus and influenza A(H3N2). These viruses are more resilient, spreading earlier and more widely, leading to higher infection rates and more severe symptoms. Factors such as colder weather, increased indoor activity, and waning immunity after previous seasons also contribute to the surge.
-
What viruses are causing the increase?
The main culprits behind this rise are adenovirus and influenza viruses, particularly the early-emerging A(H3N2) strain. Adenovirus is causing longer-lasting sore throats and is resistant to common disinfectants, while influenza is responsible for a sharp increase in hospitalizations and fatalities, especially among vulnerable groups.
-
How can I protect myself from these viruses?
Protection measures include getting vaccinated against flu, practicing good hygiene like frequent handwashing, avoiding close contact with sick people, and disinfecting surfaces regularly. Wearing masks in crowded places and maintaining good respiratory hygiene can also help reduce your risk of infection.
-
What are the symptoms of these respiratory infections?
Symptoms can include severe sore throats, cough, fever, fatigue, and in some cases, difficulty breathing. Adenovirus infections tend to last longer and are harder to treat, while flu symptoms often come on suddenly with high fever and body aches. Early detection and treatment are crucial, especially for vulnerable populations.
-
What treatment options are available?
Treatment mainly focuses on relieving symptoms through rest, hydration, and over-the-counter medications. In severe cases, especially with influenza, antiviral drugs may be prescribed. It’s important to seek medical advice early if symptoms worsen or if you belong to a high-risk group, such as the elderly or immunocompromised.
-
Are vaccines effective against these viruses?
Yes, vaccines are a key tool in preventing severe illness from influenza and some adenoviruses. The flu vaccine is updated annually to match circulating strains and is especially recommended for vulnerable groups. While no vaccine covers all adenoviruses, vaccination combined with hygiene measures can significantly reduce your risk.
