Is it just a common cold, or something more? Adenovirus infections are highly contagious and can affect anyone, especially children. Knowing the signs is crucial for protecting your family's health and preventing an outbreak.

What are the main causes of Adenovirus Infection?

  • Adenoviruses are a group of common viruses that can infect the lining of your eyes, airways, lungs, intestines, urinary tract, and nervous system.
  • The virus spreads easily through close personal contact, such as touching or shaking hands with an infected person, or through the air by coughing and sneezing.
  • You can also get infected by touching surfaces contaminated with the virus, like doorknobs or toys, and then touching your eyes, nose, or mouth.

Key symptoms of Adenovirus Infection to watch for

  • Common symptoms often resemble a cold or flu, including sore throat, fever, runny nose, and cough, which typically last for about one to two weeks.
  • Adenovirus can cause specific conditions like bronchitis, severe pneumonia, and highly contagious conjunctivitis, also known as adenovirus pink eye.
  • Some strains may cause gastroenteritis, leading to diarrhea, vomiting, and stomach cramps, which is a common presentation of the infection in young children.

How can you prevent Adenovirus Infection effectively?

  • The best prevention method is to wash your hands often and thoroughly with soap and water for at least 20 seconds, especially after coughing or sneezing.
  • Make a conscious effort to avoid touching your face, particularly your eyes, nose, and mouth with unwashed hands to prevent the virus from entering your body.
  • If you are sick, stay home to avoid spreading the highly contagious virus to others at work, school, or in other public places.
