Viruses hijacking infected individuals’ natural defense mechanisms is old news. It has long been known that doing so increases viral propagation through the population, but it is not clear how these viruses work. Researchers have searched for infectious cough’s mechanism for years, given that find...
How long is encephalitis contagious? Is polymyalgia rheumatica contagious? Is babesiosis contagious? Is adenovirus contagious? Is an infectious disease contagious? Is a viral disease contagious? Is Behcet's disease contagious? Is leishmaniasis contagious?
For example, rhinovirus — the viruses that cause the common cold — will survive for a short time on surfaces. However, others such as the norovirus, which is a virus that can cause vomiting and diarrhea — can survive for weeks. Not surprisingly, with its ability to live this long out...
Because the symptoms of norovirus are similar to those of other common viral diarrheas likerotavirus, it is necessary to do specific tests to identify the virus. Norovirus cannot be cultured in a laboratory. However, the RNA inside the virus may be detected directly usingpolymerase chain reaction...
They are infectious agents with only a protein shell and a strand of RNA or DNA, depending on the type of virus. They do not reproduce on their own—like bacteria do. Instead, viruses need a host cell to do the reproducing for them (you’ll learn more about that below.)...
When we say that we are immune to a specific infectious agent, what are we talking about? How many different types of immunity are there? Tell us a bit about each and how it works. How could we respond if a new pandemic ...
Vaccines are vital for any cat’s long-term well-being and quality of life, but for a short period after receiving them, shots can cause several irritating side effects. Mild pain is typical, as is mild tiredness. Depending on your cat’s personality the stress of the vet visit could co...

and post-vaccine eras. they found that for two to three years after measles epidemics spiked, non-measles deaths also increased. they argued that the virus was predisposing children to other infectious diseases. no one had noticed before because in the pre-vaccine era, virtually everyone got ...
Why are these strains usually more infectious and lethal than common flu strains? Why is the influenza virus considered one of the most dangerous viruses? Why doesn't the flu vaccine always work? Can a flu shot from last year protect you from getting the flu this year? Why or why...
