Can you get another strain of HIV?

When a person with HIV gets another type, or strain, of the virus it is called HIV superinfection. The new strain of HIV can replace the original strain or remain along with the original strain.

Can I get reinfected with HIV while on treatment?

HIV reinfection doesn’t happen frequently. When it does, the person getting another strain of HIV has usually been diagnosed with HIV within the last four years and isn’t taking HIV treatment. Reinfection does not cause serious health problems for most people living with HIV.

How common is HIV reinfection?

Cases have been reported globally and studies have shown the incidence rate to be 0–7.7\% per year. Research from Uganda published in 2012 indicates that HIV superinfection among HIV-infected individuals within a general population remains unknown.

Can an undetectable person get reinfected?

An undetectable viral load indicates your HIV isn’t resistant to your medication. If you have a detectable viral load or don’t know whether the person you’re having sex with is undetectable, using condoms will prevent reinfection.

How likely is Covid reinfection?

Estimates based on viral evolution forecast a 50\% risk 17 months after a first infection without measures such as masking and vaccination. People who have been infected with SARS-CoV-2 can expect to become reinfected within one or two years, unless they take precautions such as getting vaccinated and wearing masks.

Can you get reinfected with Covid within 3 months?

A Michigan Medicine study found that most patients with mild COVID-19 infections produce antibodies that persist and protect them from reinfection for up to six months. Researchers analyzed nearly 130 subjects with PCR-confirmed COVID-19 illness between three and six months after initial infection.

Can you get Covid twice after being vaccinated?

People who’ve been vaccinated can also contract COVID a second time, but the chance is far lower than for those who’ve gotten the vaccine. “There is a very, very small chance,” Esper said.

Does HIV superinfection cause a sustained increase in viral load?

Studies indicate that superinfection causes a spike in HIV viral load and a decrease in CD4+ cell count similar to those reported during primary HIV infection. Early studies of HIV superinfection analysed these spikes to diagnose cases of superinfection. It is unclear whether superinfection causes a sustained increase in viral load.

What is the difference between HIV dual infection and superinfection?

HIV superinfection is distinct from HIV dual infection, where an individual is simultaneously infected with multiple distinct viral strains. HIV superinfection involves an individual with HIV being infected by a new, phylogenetically distinct HIV strain.

What is the prognosis of superinfection in HIV infection?

Studies indicate that superinfection causes a spike in HIV viral load and a decrease in CD4+ cell count similar to those reported during primary HIV infection.

Does infecting subtype matter for people living with HIV?

The outside coating of HIV is the area most prone to variation, which makes it particularly difficult to make a vaccine that protects against all HIV strains. That’s why subtype is important to scientists. But does the infecting subtype matter for people living with HIV? With some minor caveats, the answer is no.
