Adenoviruses are common viruses that can cause a variety of illnesses in humans, including respiratory illnesses, conjunctivitis, and gastrointestinal diseases. They are often spread from person-to-person through close contact and can be transmitted through contact with contaminated feces, saliva, or respiratory secretions.
The four symptoms of adenoviruses are:
1. Respiratory Symptoms: Common symptoms include fever, sore throat, a cough, and difficulty breathing. In some cases, pneumonia or bronchitis may also develop.
2. Conjunctivitis: This is an inflammation of the conjunctiva, the thin, transparent membrane that lines the eye and the inside of the eyelids. Symptoms include redness, itching, burning, and discharge.
3. Gastrointestinal Symptoms: These can include abdominal pain, vomiting, and diarrhea.
4. Genitourinary Symptoms: These can include painful urination, frequent urination, and blood in the urine.
In some cases, adenoviruses can cause more serious complications, including meningitis, encephalitis, and inflammation of the heart. It is important to seek medical attention if any of the four symptoms listed above are present. A doctor can diagnose the infection and prescribe the necessary treatment.
