Document Summary
Protein coat surrounding genetic material genetic info may be dna or rna. Dna may be a single strand or multiple fragments: multiple chromosomes. Immune system learns to make antibodies for this protein coat. Debate as to whether it is life or not. Changes might cause antibodies to bin less ef ciently. This is why we have new viruses each ew season. Came from multiple strains shuf ed into a single host bird. Kills 1/3 people it comes in contact with. Believed that increased human density has allowed hiv to spread more easily. Can be used to determine if someone gave someone else a disease. If a virus can travel from host to hot more easily, it will be more virulent: with larger populations, viruses are more virulent. Lower virulence may be encouraged: making it harder to pass viruses along. Increased virulence may be encouraged by crowding in prisons. Refugee camps breakdowns in hygiene rapid trans-global travel.
