Arthritogenic alphaviruses are mosquito-borne viruses that cause a debilitating rheumatic disease characterized by fever, headache, rash, myalgia, and polyarthralgia with the potential to evolve into a severe and very prolonged illness. Although these viruses have been geographi...
For the virus to be able to multiply and cause disease it is essential that it can penetrate into any cell in our body. This process is not always simple. Our cells have on their surface molecules that act as a kind of lock. For any structure that can cross the cell wall is necessary...
Overall, the viruses that cause acute respiratory infection worldwide are the same (Table 19.1), but there are local variations, particularly during outbreaks of unusual organisms (Nipah virus in Bangladesh and India). In temperate parts of the world, there is a clear seasonal pattern in the pr...

The ECHO viruses (enteric cytopathogenic human orphan viruses) comprise a subgroup of the human enteroviruses: all are infectious for human beings. Although several may share common antigens, most are serologically unrelated. They have been grouped toget
Griffin noted that the battle between the immune system and the measles virus is happening in other organs, presumably leading to lesions there as well; we just can't see them like we can on the skin. And the rash is actually a welcome sight—if people have a mild rash or no rash at...
