What It Means To Have ‘Undetectable’ Hiv—And Why You Need To Know

It’s been almost 40 years since the start of the AIDS epidemic, when hundreds of people began contracting deadly infections that doctors had no idea how to combat. It took until 1983 for researchers to identify the virus that was causing their symptoms: human immunodeficiency virus, or HIV. After years of medical testing, protests, and millions of deaths the world still hasn’t emerged from the epidemic. But it’s getting closer: Since their peak in 2004, AIDS-related deaths have shrunk by over half, and new HIV infections have reduced by 40 percent since 1997.

Safe sex practices and pre-exposure prophylaxis (PrEP) medications have prevented many further infections, and the evolution of antiretroviral (ART) treatments have stalled the virus from replicating in people who already have it. Beyond allowing people with HIV to live completely normal lives, these drugs also prevent them from transmitting the virus to others once they reach an undetectable viral load. But in many communities, people living with undetectable HIV statuses still face stigma that marginalizes them as “dirty” and unsafe to have sex with. Here’s how the science disproves that.

To understand why someone who is HIV positive but whose infection is undetectable can’t transmit HIV to a sexual partner, it’s vital to understand both how the virus itself infects the body and how medications work to combat it. Left unchecked, the HIV virus hijacks CD4 immune cells, a type of white blood cell responsible for fighting off infections, to make more copies of itself. As their viral load (number of virus copies per milliliter of blood) skyrockets, an afflicted person’s number of CD4 cells plummets, leaving them vulnerable to opportunistic infections. Once the CD4 count dips below 200, HIV has caused AIDS.

The first antiretroviral drug used to treat HIV was called AZT. Originally developed in the 1960s as a cancer treatment, AZT interfered with DNA replication in a person’s HIV-infected, CD4 immune cells to prevent the virus from taking over their immune system. But it was also incredibly toxic, causing anemia, nausea, insomnia, and weakened immune systems in many patients. Over the past few decades, researchers have developed antiretrovirals that are far more effective and less damaging, says Christopher Hall, vice president of medical affairs for the San Francisco AIDS Foundation.

“The evolution has been to a pill that is extremely well-tolerated, taken only once a day,” Hall says. “That’s just an incredible development.”

ART medication gives the cells a hand in combating HIV, which prevents it from replicating. A patient’s viral load then begins to decline while their CD4 count returns to normal. Originally, scientists thought that no matter how low their viral load was or how healthy they were, someone living with HIV could still give the virus to a sexual partner. But by 2000, studies began showing that below a certain threshold, that risk was incredibly rare.

While each person diagnosed with HIV has their own treatment timeline, almost all providers will have their patients begin taking ART medication as soon as they’re diagnosed. Hall says that’s a shift from how things used to be: Doctors would wait to determine whether their patients were ready and able to take the drugs (the original meds needed to be taken up to four times a day and caused a slew of side effects).

Because modern-day ART medications have so few drawbacks, a patient can start treatment right after their diagnosis and immediately see their viral load drop. Hall says that’s also important for combating the stigma that HIV is a death sentence, because at this point, it isn’t.

“We want to say, ‘Hey, you can get on top of this right away. This is going to be easy for you to manage, relatively speaking. We’re going to help you,’” Hall says.

Depending on the patient’s condition, they’ll return to the doctor after about a month to discuss how they’re tolerating the medication. The provider will run tests on their kidney and liver function and check for anemia. They’ll also run a viral load test, which scans for any genetic material associated with HIV in the bloodstream to determine the number of virus copies per milliliter of blood. Once the medication has done its work and that number reaches 200 copies per milliliter (usually after about 6 months), a person is considered undetectable.

But why do doctors say “undetectable” if the virus can still be detected by the test? Hall says that’s a function of how specific viral load tests have become over the years. When a test that can only measure as low as 200 copies per milliliter arrives at that result, it’s likely that the patient could have an even lower viral load than that. But because the test can’t measure anything lower than 200, they’re deemed undetectable.

Viral load tests get more specific by the day: Hall says some are still in the works that can get as precise as 1 to 5 copies per milliliter range. The tests he uses in his clinic can see down to 20 copies per milliliter, but he says that doesn’t mean his undetectable patients are more undetectable than those who’ve used the 200 copies per milliliter test.

“There’s some nuances to it,” Hall says.

Two hundred is still the golden number for people living with HIV, because that’s the most specific test that was used in the studies that proved an undetectable person can’t transmit the virus. Hall says below that point, an HIV-negative person with a healthy immune system can easily fight off a couple hundred viruses as opposed to the millions contained in a milliliter of blood from a newly diagnosed person. Our skin and mucous membranes do an excellent job protecting us from invaders, even HIV.

“HIV is inefficient enough that, when present in low numbers, infection can be avoided,” Hall says.

Dave Watt, outreach manager for the Southwest Center for HIV/AIDS, fields all kinds of conspiracy-like questions from folks who are uninformed about HIV, down to whether or not mosquitoes can transmit the virus (they can’t, he says, otherwise everybody would have HIV by now). Over a decade ago, he founded the Friendly campaign, which aims to counteract the fear-based messaging that often surrounds the virus. Even after the CDC formally endorsed the “U=U” campaign (which asserts that undetectable HIV is untransmittable) in 2023, Watt says it can be tough to help people understand that medical truth.

“While science can’t say it’s impossible, that’s just not how science works,” Watt says. “We used to say ‘low risk’ or ‘minimal risk.’ And now the studies have shown that there really is no risk.”

In 2023, the groundbreaking PARTNER study, a large, international research initiative that studied 900 serodiscordant couples (i.e. one partner had an undetectable viral load and the other tested negative for HIV), found that even after multiple years of condomless sex, not one person transmitted the virus to their partner. A number of clinical studies have since verified this, and scientists say the risk of an undetectable person transmitting the virus to their HIV-negative partner is effectively zero.

ART can’t cure HIV—with today’s treatment options, an undetectable person will always test “positive” for the virus. And during the antiretroviral onslaught, the virus will retreat into “sanctuary” areas like the rectum or cervix, allowing it to begin replicating again if the person stops taking the drugs. The ART drugs can’t access those “sanctuary” areas very well, so they can’t eliminate every last virus left. But, when taken diligently, the meds keep HIV so well at bay that, effectively, they may have the potential to end the epidemic without scientists finding a definitive cure.

The concept of treatment as prevention (TasP) emphasizes the importance of immediately treating anyone diagnosed with HIV in order to get them to undetectable status as quickly as possible. Once they become undetectable and continue taking the medications, they’ll be unable to transmit the virus any further. If everyone living with HIV gains access to these lifesaving drugs, they can stop the disease in its tracks. But even when communities do have the resources, fear can stop them from seeking treatment.

Hall says when people fear the consequences of getting HIV and don’t realize that it’s no longer a death sentence, they’re less likely to get tested in the first place. This delay makes their conditions more difficult to treat because the virus has had a longer amount of time to take hold on their immune systems. But telling people that, at the end of the treatment, their risk of infecting others is essentially nonexistent can be a powerful tool in lifting that stigma.

Governments also have to catch up with the science. In the U.S., 29 states have laws that criminalize people living with HIV, whether it’s not disclosing their status to a sexual partner or being punished for physically transmitting the virus to their partners. Nine states have measures that enhance prison sentences for sex crimes when a person living with HIV is involved. In some cases, these sentences may be harsher than ones for murder.

“Stigma continues to be the greatest challenge in ending the epidemic,” Hall says.

There are many things that can cause the error code in question. Sometimes, it can be because of faulty hardware, such as Hard Drive or RAM. It can also be due to outdated drivers. This is a very common issue, usually, when you update your Windows, your drivers get updated. But when you don’t update Windows, or if Windows Update doesn’t include the latest installation package for the driver, you will see the error code.

There are some other reasons as well that we will be seeing later in this article.

Fix Error Code 0x0000FFFF on Windows computer

If you want to fix Error Code 0x0000FFFF on Windows, then follow the given solutions.

Update your drivers

Troubleshoot in Clean Boot

Perform a Cold Restart

Check your RAM

Scan for Virus and Malware


Analyze your Mini-dump file(s)

Let us talk about them in detail.

1] Update your drivers

As mentioned earlier, you need to make sure that your drivers are up-to-date. To do that, first, try updating your Windows. Most of the time, when you update your OS, the drivers automatically get updated. If that didn’t work, then try downloading the drivers from the manufacturer’s website or use a Driver Update software.

Once you update the driver, check if the issue persists.

2] Troubleshoot in Clean Boot

The issue can occur because of a third-party application interfering with your program. That’s why try troubleshooting the issue in Clean Boot. This way, you will get to know which application is causing, then you can remove it to resolve the issue.

3] Perform a Cold Restart

You can see the error code in question because of the faulty connection of hardware to the motherboard such as your RAM or Hard Disk. Performing a Cold Restart will resolve the issue. Follow the given steps to do the same.

Turn off your computer and any other connected device.

Remove all the plugs and disconnect all the wires.

Wait for a minute or two and then restart your computer.

Once you do that, check if you are still seeing the error code in question.

4] Check your RAM

If you have a desktop with multiple RAMs, then checking whether a RAM is faulty or not is easy. Just plug one out, restart the system and see if the issue persists. If you are not seeing the error message, then one of the RAMs is faulty. In case, you are still seeing the issue, plug that RAM back in, remove the other RAM, restart the computer, and check.

But if you have a Laptop or a Desktop with just one RAM, then a visit to an expert is a must. Then have tools and techniques to resolve the issue.

5] Scan for Virus and Malware

Next up, try scanning your computer for viruses and malware. You can use any third-party antivirus or Windows Defender to do the same. To use Windows Defender, follow the given steps.

Hit Win + S, type “Windows Security” and open the app.

Let it run and hopefully, your issue will be resolved.

6] Run SFC

If your system files are corrupted, you will see the BSOD. To resolve it, we need to run the System File Checker or SFC. It is a command that can resolve BSODs. So, open Command Prompt as an administrator and execute the following command.

sfc /scannow

Then, restart the computer and see if the issue is resolved.

7] Analyze your Mini-dump file(s)

If you are getting BSOD then check your Mini-dump file(s). This is the file that contains information about the BSOD and crashing issue.

Open File Explorer and go to the following location.

How To Fix Windows Error Code 0Xc00000E9

Error code 0xc00000e9 is an issue that’s often encountered during the Windows boot process. Unlike other errors that you can diagnose and fix within the regular Windows environment, error code 0xc00000e9 may not allow you to do that. More often than not, it will prevent you from booting into Windows because of faulty hardware, corrupted files, damaged boot files, or even a malware infection. We’ve compiled a list of the most useful fixes that, in all likelihood, will resolve error code 0xc00000e9 on your system.

1. Check Your Hardware

Error code 0xc00000e9 is accompanied by the description “An unexpected I/O error has occurred.” This usually indicates that the issue is directly related to your system’s hardware – peripherals or components.

Devices like keyboards, mice, printers, and scanners could be at fault here. Similarly, the issue could lie with internal components, like the RAM, graphics card, and storage drives. To locate the faulty device, follow the steps below:

Turn off your system, and unplug each of your peripheral devices, like the mouse, keyboard, printer, etc.

Restart your computer and see whether you’re able to boot to the desktop. If you can, one of the devices you disconnected is behind the error.

Turn off your computer, and start reconnecting each device one after the other, rebooting your computer every time. Check which device causes the error to resurface.

If the error didn’t disappear even after removing all the peripherals, you’ll need to move on to the internal components of your system. If you’re comfortable opening up your PC case or laptop, try disconnecting your RAM sticks, storage drives, and graphics card one by one, and proceed with the troubleshooting. If you don’t want to do it yourself, try reaching out to an expert or repair service.

2. Fix Corrupted System Files

Corrupted Windows system files are behind many different Windows errors, including error code 0xc00000e9. You can use built-in Windows diagnostics tools, like SFC and DISM scans, to fix any corrupted Windows files. If you’re able to boot into Windows, run SFC, then DISM scans, using the Command Prompt.

However, if you’re stuck in a blue screen loop, you’ll need to boot into the Advanced Startup environment to access the Command Prompt:

Reboot your computer and hold the power button to force shutdown three to four times in a row. On the next reboot, Windows will automatically boot into the Advanced Startup environment.

Select “Advanced options” on the next screen.

Select “Command Prompt” on the next screen, then follow the instructions shown in the link above.

If running the SFC and DISM scans doesn’t fix the error, move on to the next fix.

3. Update Device Drivers

Considering error code 0xc00000e9 is closely related to I/O devices, it’s important to eliminate driver issues as one of the possible causes behind the error. You can update the drivers for each of your devices, such as the mouse, keyboard, cameras, printers, and more from the Device Manager.

Once this is done, restart your computer for the changes to take effect, and check whether the 0xc00000e9 error still appears.

If you aren’t able to boot into Windows normally, you’ll need to boot into Safe Mode, then follow the above instructions.

4. Roll Back Drivers

Updating device drivers may not fix your problem. Sometimes a recent driver update can create issues that cause error code 0xc00000e9. In such cases, try rolling back your drivers. If you start experiencing the error after a recent driver update, rolling back to the last driver version can get rid of it.

Check out our guide on how to roll back a driver in Windows for detailed instructions on the same.

5. Update the Volume Boot Code

The Windows volume boot code (VBC) is a set of data contained in the volume boot record (VBR) and is responsible for the proper boot process of Windows. Sometimes it can become associated with another bootloader instead of the default Windows bootloader, e.g., BOOTMGR. This can cause serious issues with your boot process and result in BSOD errors, like error code 0xc00000e9.

Updating the VBC can resolve this issue by associating it with BOOTMGR. Follow the instructions below:

Boot into the Advanced Startup environment using the steps shown in section 2 above.

Close the window and restart your computer. Check whether the error persists.

6. Repair the MBR

The master boot record (MBR) is contained within the VBR and holds the necessary partition and boot information required to boot into Windows. Similar to the VBR, the MBR can also become corrupted and lead to errors such as the 0xc00000e9 error.

To repair the MBR, boot into the Advanced Startup environment, and execute a set of commands. Follow the steps below:

Boot into the Advanced Startup environment using the steps shown in section 2 above.



fixmbr bootrec



Restart your computer and check whether error 0xc00000e9 is resolved.

7. Run a Malware Scan

Chances are, you have your Microsoft Defender (formerly Windows Defender) turned on and configured correctly to keep all malware at bay. But sometimes it can be mistakenly turned off or misconfigured, leading to a malware infection. If none of the above fixes worked for you, run a malware scan to eliminate any malware from your system using Microsoft Defender via the Command Prompt.

Once the scan is finished, restart your computer, and check whether the error persists.

8. Use System Restore

Sometimes, if nothing else works, using System Restore can get rid of errors like the 0xc00000e9 error by reverting your system to a state where things were working normally. Try restoring your system to a date before the time you started seeing the error code.

Once the process is complete, restart your computer, and check whether the 0xc00000e9 error still appears.

9. Reset or Reinstall Windows

The fixes listed above should be able to fix error code 0xc00000e9. But if none of the solutions worked for you, there may be deeper issues with your Windows installation. In such cases, resetting Windows may be your only option.

You can reset Windows to its factory settings and remove all root causes behind the error in the process. This should ideally be a permanent fix to the problem. Reset/reinstall Windows without losing your files if you’re worried about losing your important data during this process.

Frequently Asked Questions Why I am getting a blue screen boot loop?

A blue screen boot loop is a common occurrence on Windows systems, indicative of corrupt system files, buggy Windows updates, outdated drivers, or even faulty hardware. Users often get stuck experiencing the same BSOD error, even after restarting their systems multiple times. Check out our guide on how to fix a Windows infinite reboot loop problem for blue screen boot loop fixes.

Will System Restore delete my files?

System Restore reverts your system files and settings to an earlier, more stable state. This does involve the removal of some system files and settings. But your personal files and media – like photos, videos, and music – are not deleted. However, any programs you installed after the creation of the restore point, and files/folders that were saved on the desktop, will be removed.

Why do I keep getting blue screen errors?

Frequent Blue Screen errors could be a sign of a dying disk drive. Recurring BSODs could also be caused due to other faulty hardware, such as RAM and the graphics card. Although you can get rid of the occasional BSOD with common fixes, frequent Blue Screen errors mean you should get your storage drives checked before you lose important data. Similarly, you should always inspect other components to rule out any fundamental hardware faults.
