Document Summary
In uenza (orthomyxiviridae) major factor in host tropism and virulence symptoms: fever, muscle aches/pain, cough, lung infections. Old are more susceptible to dying from disease envelope form. Different segments are produced from the assortments of viruses that are produced. This is a fairly scary situation due to the unpredictability of the newly formed virus. This causes new vaccines to be created from year to year. H3n8 jumped to dogs in 2004 (eating horse meat) canine u epidemic in 2015 (new strain) Hiv (retrovirus) can lead to aids (acquired immune de cient syndrome) enveloped. 2 identical copies (only known diploid virus) of rna w/ replication via reverse transcriptase. Rna can cause the cell to die due to disruption in sequencing. 6% of the human genome is retrovirus -some retroviruses have helped with the development of humans. Cd4 protein is found on t-helper cells, macrophages, and dendritic cells requires rt and rna pol 2 in order to fully integrate and be reproduced.
