SIV studies have shown about 100 ID50 for HIV-2 and 1,000 for HIV-1.
Ic50/id50
Neither; virulence is a subjective measure of the severity of symptoms caused by microbial infection, it is not related to the ID50 of the infecting organism. The ID50 number for an infectious agent refers the the dose required to infect half of a population; it is usually given in terms of individual organisms. A higher ID50 equals more difficult transmission (ignoring other factors that affect transmission), so a lower ID50 would make the agent more infectious. So, E. coli is more infectious than Salmonella, as it takes more individual salmonella organisms to cause infection.
ID50, or Infectious Dose 50, is the amount of a pathogen required to infect 50% of a given population. It helps explain variability in susceptibility among individuals; not everyone in a camp may have been exposed to the ID50 dose needed for infection. Factors such as individual immune systems, previous exposure to the pathogen, and differences in behavior or hygiene practices can also contribute to why some people became ill while others did not. Thus, those who did not reach the ID50 threshold or had protective factors would remain healthy.
ID50 is a term used in the travel industry, primarily by airlines. ID means Industry Discount, and the 50 represents the percentage of the discount. If you see ID90, for instance, it means that the ticket is available to qualified members of the travel industry for 90% off the normal ticket price. ID50 is usually used for business travelers in the travel industry and often is a positive space ticket.
ID50 is the infectious dose at which 50% of a population will become infected, typically used in epidemiology to measure the potency of a pathogen. IC50 is the half-maximal inhibitory concentration, used in pharmacology to measure the effectiveness of a drug in inhibiting a biological process.
It is low.. about 10 bacilli by inhalation

To draw an ID50 graph, first, gather data on the dosage of a substance and the corresponding percentage of subjects exhibiting a specific response (e.g., infection or toxicity). Plot the dosage on the x-axis and the percentage response on the y-axis. Create a smooth curve through the data points, identifying the dose at which 50% of the subjects respond; this is the ID50 value. Label the axes and include a title for clarity.
ID50 is an expression used to evaluate the probability of infections by pathogen microorganisms; it is not adequate for the chloride ion.

It is better to be HIV negative than HIV positive. An HIV positive person is infected with HIV.
HIV-positive means you are infected with the human immunodeficiency virus. HIV-negative means that you are not infected with the HIV.
