Shellfish, particularly oysters.
Viral conjunctivitis is highly contagious. Most viruses that cause conjunctivitis are spread through hand-to-eye contact by hands or objects that are contaminated with the infectious virus. Hands can become contaminated by coming in contact with infectious tears, eye discharge, fecal matter, or respiratory discharges. Bacterial conjunctivitis is less common in children older than 5 years of age. Globally, the bacterium Chlamydia trachomatis (trachoma) is the leading cause of preventable blindness of infectious origin. (May 2012). Conjunctivitis, also known as pink eye is inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids). It is commonly due to an infection (usually viral, but sometimes bacterial or parasitic), or an allergic reaction. Conjunctivitis can affect one or both eyes and is the most likely diagnosis in someone with eye redness and discharge (fluid coming from the eye). The affected eye is often stuck shut in the morning. Most infections with adenovirus result in infections of the upper respiratory tract. Adenovirus infections often show up as conjunctivitis, tonsilitis (which may look exactly like strep throat and cannot be distinguished from strep except by throat culture), an ear infection, or croup. Canine adenovirus 2 (CAdV-2) is one of the potential causes of kennel cough. Core vaccines for dogs include attenuated live CAdV-2, which produces immunity to CAdV-1 and CAdV-2. CAdV-1 was initially used in a vaccine for dogs, but corneal edema was a common complication. Adenoviruses of Diarrhoeal Viruses Infection. Adenoviruses. Two types of adenoviruses may be recovered from the stools, the conventional cultivable types,and the fastidious types which do not grow in routine cell culture. Both SRVs and SRSVs have been associated with common source outbreaks, of which a considerable proportion is associated with the consumption of shellfish, particularly oysters. The incubation period is 36-48 hours, following which the patient develops vomiting and diarrhoea. They have a broad range of vertebrate hosts; in humans, 60 distinct adenoviral serotypes have been found to cause a wide range of illnesses, from mild respiratory infections in young children (known as the common cold) to life-threatening multi-organ disease in people with a weakened immune system. Canine adenovirus 2 (CAdV-2) is one of the potential causes of kennel cough. Core vaccines for dogs include attenuated live CAdV-2, which produces immunity to CAdV-1 and CAdV-2. CAdV-1 was initially used in a vaccine for dogs, but corneal edema was a common complication. Asymptomatic and prolonged excretion of adenoviruses has been found in babies, which parallels the prolonged excretion from the respiratory tract. Adenoviruses have also been associated with common source outbreaks where it has been the only potentially pathogenic microorganism present. No fastidious adenoviruses have been recovered from the respiratory tract. Little is known about immunity to fastidious adenoviruses in man. Both SRVs and SRSVs have been associated with common source outbreaks, of which a considerable proportion is associated with the consumption of shellfish, particularly oysters. The incubation period is 36-48 hours, following which the patient develops vomiting and diarrhoea. Two types of canine adenoviruses are well known, type 1 and 2. Type 1 causes infectious canine hepatitis, a potentially fatal disease involving vasculitis and hepatitis. Type 1 infection can also cause respiratory and eye infections. Canine adenovirus 2 (CAdV-2) is one of the potential causes of kennel cough. Core vaccines for dogs include attenuated live CAdV-2, which produces immunity to CAdV-1 and CAdV-2. CAdV-1 was initially used in a vaccine for dogs, but corneal edema was a common complication. Apart from respiratory involvement, illnesses and presentations of adenovirus include gastroenteritis, conjunctivitis, cystitis, and rash illness. Symptoms of respiratory illness caused by adenovirus infection range from the common cold syndrome to pneumonia, croup, and bronchitis.  1 Infections of the gut-Adenoviruses are associated with 4-15% of all children hospitalized with viral gastroenteritis. 2  Gastroenteritis may be a sign of a systemic infection such as those caused by Ad3 or Ad7. 3  They may cause both respiratory and diarrhoea in a child with high fever. In summary, members belonging to the genus adenoviruses share common epitopes on the hexons. Subgenus is defined by the DNA homology of more than 50% between members within a subgenus and less than 20% between members of different subgenera. The serotype is defined by quantitative neutralization with hyperimmune sera. Adenoviruses can also spread through the water, such as swimming pools, but this is less common. What are the symptoms of adenovirus infection? Adenoviruses most often infect the airways – this can appear as a “cold” (e.g., sore throat, sneezing, runny nose, cough, headache, chills), croup, or bronchitis. Some people may also get a fever.
