# HIV and Covid-19 coinfection Questions:
## Definition of chronic COVID (vs long COVID)
When looking at articles, a careful interpretation of what is described as `chronic COVID` may be important. It is possible that this is a loosely defined term that not many people distinguish. In fact, to me, it is unclear if they are talking about the symptoms in the presence of the virus or after virus clearance (I guess symptom is really all that matters clinically.) Let's make sure what authors really mean when they say chronic or long COVID.
For our particular interest, chronic COVID must have the virus present. Thus, we would want to have information about the following in addition to the information about the co-infection of interest:
- the length of illness
- the definition of on-going COVID (the cycle threshold, Ct?)

### Median Duration of COVID
#### Summary
- Median **symptom** duration: 11 days
- Median **PCR positive viral load** duration: 28 days

> The COVID Symptom Study is **a mobile application** launched in response to the COVID-19 pandemic. ... From these, we selected 4,182 individuals who met the inclusion criteria to investigate the duration of persistent symptoms in COVID-19 (Extended Data Fig. 1). ... For individuals who had ***a positive swab*** for COVID-19 (n = 4,182 from the UK, the US and Sweden), **the overall median symptom duration was 11 (interquartile range (IQR), 6–19) days**, with 558 (13.3%) people who met the LC28 definition (median (IQR), 41 (33–63) days). Of those, 189 (4.5%) met the definition for LC56 (duration ≥ 56 d) and **108 (2.6%) for LC84 (duration ≥ 84 d; all percentages were calculated with respect to the overall sample, n = 4,182)**. In contrast 1,591 (38.0%) individuals had short COVID (median (IQR) symptom duration, 6 (4–8) days). The proportions were comparable in all three countries (UK: 3,491, US: 218, Sweden: 473; LC28: UK 13.3%, US 16.1%, Sweden 12.1%; P = 0.35; LC56: UK 4.7%, US 5.5%, Sweden 2.5%; P = 0.07).

> For the purpose of this review, we defined post-acute COVID-19 as persistent symptoms and/or delayed or long-term complications of SARS-CoV-2 infection beyond 4 weeks from the onset of symptoms (Fig. 1).

### Clinical definition
#### Summary
- Long COVID will generally indicate symptoms after infection clearance. Thus, it would be important to find data about chronic or persistent SARS-CoV-2. I found a definition for "long COVID" or Post Acute Sequelae of SARS-CoV-2 Infection (PASC), but not many scholarly papers are using the latter term.
- I have not yet found a good clinical definition of chronic or persistent SARS-CoV-2.
[Long COVID and chronic COVID syndromes](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7675759/#jmv26587-bib-0002)
> Long COVID or postacute COVID (symptoms beyond 3 weeks) and chronic post‐COVID syndrome (beyond 12 weeks) are multisystem syndromes and need a multifaceted approach to tackle the physical, cognitive, psychological, social, and vocational domains of this health condition.
[Defining Post-COVID Symptoms (Post-Acute COVID, Long COVID, Persistent Post-COVID): An Integrative Classification](https://www.mdpi.com/1660-4601/18/5/2621/htm)
> Based on the above considerations, we would like to propose the following classification for post-COVID symptoms (pending of validation in future studies). This categorization should be taken as a dynamic and complex process that may integrate potential biological, psychological, and social factors which could predispose or promote the development of post-COVID symptoms. This classification is also conditioned by whether a patient has required hospital admission or not.
> - Transition Phase: Symptoms potentially associated with acute COVID-19: symptoms up to 4–5 weeks;
> - Phase 1: Acute post-COVID symptoms: symptoms from week 5 to week 12;
> - Phase 2: Long post-COVID symptoms: symptoms from week 12 to week 24;
> - Phase 3: Persistent post-COVID symptoms: symptoms lasting more than 24 weeks.
[NIH white paper: What is the typical recovery from COVID-19?](https://www.ninds.nih.gov/Current-Research/Coronavirus-and-NINDS/nervous-system#recovery)
> Fortunately, people who have mild to moderate symptoms typically recover in **a few days or weeks**. However, some people who have had only mild or moderate symptoms of COVID-19 continue to experience dysfunction of body systems—particularly in the lungs but also possibly affecting the liver, kidneys, heart, skin, and brain and nervous system—months after their infection. In rare cases, some individuals may develop new symptoms (called sequelae) that stem from but were not present at the time of initial infection. People who require intensive care for Acute Respiratory Distress Syndrome, regardless of the cause, usually have a long period of recovery. Individuals with long-term effects, whether following mild or more severe COVID-19, have in some cases self-identified as having “long COVID” or “long haul COVID.” **These long-term symptoms are included in the scientific term, Post Acute Sequelae of SARS-CoV-2 Infection (PASC).**
### Clinical interest
#### Summary
- Clinically, it may be interesting to have emphasis on patients or host (symptoms and physiology). But what is it like in terms of the virus? How does the virus change during persistent COVID? How does SARS-CoV-2 interact with other viruses that may be present?

[SARS-CoV-2 evolution during treatment of chronic infection](https://www.nature.com/articles/s41586-021-03291-y.pdf)
- Summary:
- Chronic infection with SC2 leads to viral evolution and reduced sensitivity to neuralizing antibodies in an immunosuppressed individual treated with convalescent plasma, by generating whole-genome ultra-deep sequences for the 23 time points that span 101 days and using in vitro techniques to characterize the mutations revealed by sequenceing... These data reveal strong selection on SC-2 during convalescent plasma therapy, which is associated with the emergence of viral variants that show evidence of reduced susceptibility to neutralizing antibodies in immunosuppressed individuals.

- Summary:
- After five months of persistent SARS-CoV-2 replication in this immunocompromised patient, the virus was found to have evolved rapidly between the day 58 and 158 samples. Specifically, it acquired six additional non-synonymous SNPs and a deletion which then became fixed in the viral genome over the duration of infection. There were three specific mutations in the spike protein for which there is evidence of biological effect. The ΔH69/ΔV70 deletion is present in the B.1.1.7 VOC (26). The mutation came to attention as one of a cluster of five mutations in the spike protein associated with spill over of SARS-CoV-2 to mink. Of the five mutations, a combination of ΔH69/ΔV70 and Y453F are sufficient to evade neutralising antibody recognition (29). The same combination was identified in the viral sequence present in a persistently infected immunocompromised patient (30), suggesting convergent evolution
