researchers have found an entero virus appearing in samples in more than a dozen of the caveses they have sampled. ev71 was discovered in the 1960s in the u.s. where it was blamed for an outbreak of neurological disease in california. it is associated with hand foot and mouth disease. there is no known treatment for it. the world health organization warns the discovery of ev71 does not mean the problem of the undiagnosed cases has been solved. a lot more analysis and testing is needed. in the meantime, health officials in cambodia are trying to make sure parents with sick children know, if their child is having any of the symptoms, bring the child directly to the hospital. this family tried treating their child at home first. a week later his grandma brought him to the hospital in dire straits. to her relief, doctors finally diagnosed him with dengue fever. not the unknown illness that has already taken dozens of children's lives in just four months. sara seidner, cnn, cambodia. >>> now to syria. international peace envoy kofi annan arrived in the capital of damascus today for a meet

what you just heard about with regard to the entero virus was based on 24 patients. you start looking at the history of the patient. what medications did they receive? is there something in common between all these patients and trying to piece it together that way. it's really, you know, a true investigation, true medical investigation, anderson. >> do we know if this is contagious? how worried should people in m cambodia be or people traveling to cambodia be? >> well, you know, this is another piece of the puzzle in a way. enterovirus 71, which you just learned about there, typically is contagious. this is a virus you've seen in many parts of the world. you'd expect another child in that same household or a sibling to get it or certainly in the community. that's called clustering. they haven't seen that here, anderson. that's a bit of a mystery. why wouldn't you see that sort of transmissibility? in a way it's good news that it's not contagious the way we'd expect but it also leads to more questions, anderson. >> the number you were talking about, there's a lot of d

would the entero virus lead to this?porter: and that's where the investigation goes next. cam bodyio health officials and the w.h.o. say they are looking into whether expired medication, the wrong medication or inappropriate medications such asteroids could be to blame. steroids can also make a relatively harmless infection something much more severe. >> yes. that is definitely a possibility. >> so sanjay, a question for you. expired drugs may be causing this? how can they determine if those drugs were indeed the cause? >> it's very hard to do. they talk about laboratory testing, but it's very hard to find, first of all, the presence of the medication and to confirm in any way that it was an expired medication or a bad batch of medications as well, so, carol, i mean, they real very to do an investigation here. they go to the places where these children lived, try and figure out what medications they were taking or had been prescribed, and then see if there's something in common here, investigate those medications and see

could this entero virus have worsened with some of the medications. it is hard to figure out.e of that enterovirus, it was tough to pin it down, finding a particular drug is even more challenging. what they're going to try to do is go to some of the places the children lived, find out if they were prescribed certain medications, what they took, see if there's something in common here that may help them drill it down. but this is a real medical investigation, wolf. >> should people in cambodia, adults, others traveling to cambodia be worried now? does this just effect children? what do we know about that? >> it seems to just effect children for the time being, you know, and this has been since april now. this is unlikely first of all to effect adults. typically when you talk about hand, foot and mouth disease, it does typically tend to be a disease of children. i will also say that if there is good news in all of this, wolf, it does not appear to be contagious, even within households where the children lived, didn't appear to spread within the household or cluster as they call
