Hepatitis B is a liver disease caused by the hepatitis B virus (HBV). It ranges in severity from a mild illness, lasting a few weeks (acute), to a serious long-term (chronic) illness that can lead to liver disease or liver cancer. Transmission: Contact with infectious blood, semen, and other body fluids from having sex with an infected person, sharing contaminated needles to inject drugs, or from an infected mother to her newborn. Vaccination: Hepatitis B vaccination is recommended for all infants, older children and adolescents who were not vaccinated previously, and adults at risk for HBV infection.

Heys guys! Well todae we learnt a great deal about the differences between picornaviridae and orthomyxoviridae. A lot of us often used the word flu and cold interchangeable, but do u reallie know tat they is a huge differences between them?? Surprised?? Well dunt be as there is more to come….
Aniwae just to tok abt the differences, we as a group have sat down and discuss on ways to like summarized it all to like make it easier to like study for the exams and also make it easier for us to differentiate them. I’m sure you won’t wanna lose yr face in front of your frens rite??
Well, the differences are not only in the symptoms. There are also a lot of differences in the morphology, genome, pathogenesis, lab diagnosis, epidemiology and prevention.
well some pictures on picornaviridae:
well, here are some interesting articles related to the topic above:

Transmission through sexual contact, blood and blood products or during pregnancy.
Video below shows the HIV life cycle. If it does not appear, click the link below
hey guys!! well lets tok abt virology!!Virology is the study of viruses and virus-like agents: their structure, classification and evolution, their ways to infect and exploit cells for virus reproduction, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy. Virology is often considered a part of microbiology or of pathology. Virology is that branch of life science,which deals with the study of virus and virus-like agents,in terms of structure,classification,evolution,virulence and their culture. well, hope u guys uds now..hahs...well, ill let u noe more abt virology!!
