Difference Between Hiv 1 And Hiv 2

However heterosexual transmission rates of HIV-2 are five to 10 times lower than those of HIV-1. Our Range May Suit You.

One reason HIV-1 rates are so much higher is that HIV-1 is a far more viral strand.

Difference between hiv 1 and hiv 2. HIV-1 is the most common type of HIV and accounts for 95 of all infections whereas HIV-2 is relatively uncommon and less infectious. During progression HIV-1 has lower CD4 counts than HIV-2. In later stages HIV 2 becomes more infectious than HIV 1 but it is more likely that the disease has already been discovered and.

The fact remains that many people still do not know that HIV is of two types. Such being the case treatment options differ greatly depending on which type of HIV a patient has. Difference between HIV 1 And HIV 2 HIV 1 is more common worldwide.

In the early stages of the disease HIV 1 is more infectious and is probably the reason why it spreads much faster than HIV 2. HIV-1 is more virulent and more infective than HIV-2. Much easier to pass and much easier to contract than HIV-2.

Clinically HIV-2 infected individuals seem to dichotomise most remaining long-term non-progressors whereas most HIV-1 infected individuals progress. HIV-2 is less fatal and progresses more slowly than HIV-1. On a structural level HIV-1 and HIV-2 have important genetic differences.

The difference between HIV-1 and HIV-2 are as follows HIV-1 is the most common type of HIV and accounts for 95 of all infections whereas HIV-2 is relatively uncommon and less infectious. A technical description of the difference is that the vpu gene found in HIV-1 is replaced by the vpx gene in HIV-2. Another notable difference between HIV-1 and HIV-2 is their degree of virulence and infectivity.

So when we generally say HIV we are referring to HIV-1. Average level of immune system activation are lower. HIV-2 is mainly concentrated in West Africa is less deadly and progresses more slowly.

HIV-2 is most common in western Africa and is becoming more common in India although numbers there are still relatively small. Based on genetic similarities the numerous virus strains may be classified into types groups and subtypes. This strain is less likely to progress and many of those infected remain lifelong non-progressors.

HIV-2 is more than 55 genetically different from HIV-1. The first notable difference between the two types of HIV is that HIV 1 is ubiquitous and widespread among people especially in Africa. HIV-1 which was discovered first is the most widespread type worldwide.

Furthermore it also has more capacity for horizontal transmission within a population. It has more ability to infect and damage a host cell. The natural history of HIV-2 infection tends to be more benign than that of HIV-1 and most patients.

In terms of genetic characteristics HIV-1 and HIV-2 are only about 55 percent identical to one another. HIV-2 is mainly concentrated in West Africa and the surrounding countries. When clinical progression occurs both diseases demonstrate very similar pathological processes although progression in HIV-2 occurs at higher CD4 counts.

HIV 2 develops more slowly. Average level of immune system activation are higher. Our Range May Suit You.

Ad Talk To Us - Distributor of High Quality Hearing Aids. HIV 2 is lower transmissibility. What is the difference between HIV-1 and HIV-2.

Introduction to HIV types groups and subtypes HIV is a highly variable virus which mutates very readily. The percentage of those with HIV 2 is not as much as those with HIV one. Although HIV-2 generally progresses more slowly than HIV-1 some HIV drugs NNRTIs like nevirapine and efavirenz do not work against HIV-2.

There is one called HIV 1 and the second is HIV 2. HIV-1 was discovered first and is more prevalent worldwide while HIV-2 is less pathogenic and is mostly confined to West Africa. This means there are many different strains of HIV even within the body of a single infected person.
