References for COVID-19 related telehealth and telemedicine by journal

Telehealth are health-related services and information through electronic communication technologies to help patients with or people influenced by COVID-19. It allows long-distance patient and clinician care, education, and monitoring. Telemedicine is sometimes used as a synonym, or is used in a more limited sense to describe remote clinical services, such as diagnosis and monitoring.

Telehealth Programs

Despite developments in technology, access is still a major issue.

Globally, only 24% of the most vulnerable have access to internet connection, versus 74% of the least vulnerable according to 2019 polling by Gallup’s Basic Needs Vulnerability Index.   Although this divide is notable globally,  this inequity is even more pronounced in developing economies in which the least vulnerable are more than three times as likely to have internet access than the most vulnerable.  This presents a major challenge to telemedicine as an accessible institution. 

This is in part due to prohibitively high costs for individuals and in part due to limitations of infrastructure which pose the largest barriers in rural regions and developing countries.

Limitiations to Telemedicine Access

Due to differences in testing and case definitions, as well as how new COVID-19 is, the fatality of the virus is not well-defined yet.

Fatality of COVID-19

Countries have implemented multiple control strategies for reducing the spread of COVID-19, such as closing schools and businesses to enforce social distancing.

Struggle pertaining to controlling the virus:
The epidemiology of the respiratory virus changes rapidly. Reponses have to be nimble. Given that everyone is susceptible to for which we lack effective biologic interventions, the response has required large-scale behavior change, including social distancing and public masking.

Control Strategies for COVID-19

- Age
- Education
- Employment
- Ethnicity
- Gender
- Income
- Marital status
- Race

Epidemiological studies on COVID-19 Categorized by Continents

The progression of COVID-19 varies greatly by individual and demographic, as do many of the factors related to the disease. Studies have been analyzing the disease progression timeline, or the time frames before patients feel symptoms, are admitted to the hospital, are admitted to the ICU, are put on a mechanical ventilator, experience acute respiratory distress syndrome, etc. Not every COVID-19 case will reach each of these events.

COVID-19 Clinical Disease Progression Timeline

- 0-19 (n=123): 0%
- 20-44 (n=705): 0.1–0.2%
- 45-54 (n=429): 0.5–0.8%
- 55-64 (n=429): 1.4–2.6%
- 65-74 (n=409): 2.7–4.9%
- 75-84 (n=210): 4.3–10.5%
- greater than or equal to 85 (n=144): 10.4–27.3%
- Total (n=2,449): 1.8–3.4%

Case-Fatality Among COVID-19 Patients in the United States by Age

Following a primary infection of SARS-CoV-2, some patients acquire a secondary infection of SARS-CoV-2, or a co-infection with a different bacteria or virus

Secondary/Co-Infections of COVID-19

COVID-19 patients have gone through laboratory testing to determine the impact and extent of SARS-CoV-2 on the body.

COVID-19 Laboratory Results

The spread of the SARS-CoV-2 virus has produced or highlighted disparate outcomes of different types between population groups all over the world. Health disparities can highlight inequitable access, treatment, etc. within a country or state and often indicate the need for public health intervention.

Disparate COVID-19 Outcomes

Due to the varying experiences for those with COVID-19, recovery and rehabilitation look different for many individuals. As a baseline, "for persons recovered from COVID-19 illness, CDC recommends that isolation be maintained for at least 10 days after illness onset and at least 3 days (72 hours) after recovery. Illness onset is defined as the date symptoms begin. Recovery is defined as resolution of fever without the use of fever-reducing medications with progressive improvement or resolution of other symptoms. Ideally, isolation should be maintained for this full period to the extent that it is practicable under rapidly changing circumstances."

COVID-19 Recovery & Rehabilitation

- Resuscitation
- Convalescent Plasma (CP) Transfusion

COVID-19 Patient Interventions

The seroprevalence of COVID-19 is the measurement of the level of the pathogen in a population. There have been difficulties with estimating the seroprevalence in large populations because of the unknown qualities of COVID-19, expense in widespread population collection, asymptomatic infection, etc.

Seroprevalence of SARS-CoV-2 (COVID-19) 

A communicable period is defined as the interval from the first day of positive ribonucleic acid test to the first day of continuous negative test. For COVID-19, the communicable period has been established as two days before onset of symptoms until three days of symptom relief and no fever. 

Communicable Period of COVID-19

- Fever (when high temperature is measured)
- Laboratory confirmation of illness via viral testing
- Radiological lung abnormalities such as ground-glass chest and stripe shadowing


Clinical Characteristics of Asymptomatic COVID-19 Patients

Presence and severity of symptoms of COVID-19 depend largely on individual characteristics. COVID-19 produces both symptomatic and asymptomatic infection.

Symptomology of COVID-19 

The psychological effect COVID-19 is having on the populations affected by the pandemic

Psychological Effects of COVID-19 Pandemic

COVID-19 comorbidities are high risk conditions that put patients at greater risk for infection and negative outcomes. Some COVID-19 comorbidities have been found to be: 
- Cancer 
- Cardiovascular Disease
- Diabetes
- Digestive Diseases
- HIV
- Hypertension
- Immunological Disease
- Liver Injury
- Obesity
- Renal disease
- Respiratory System Disease

COVID-19 Patient Comorbidities

- Schools (K-12)

- Universities/Colleges

- Summer Camps

- Daycares

- Nurseries

Re-opening Childcare/ Educational Environments

COVID-19 is spread through person-to-person transmission. The virus spreads mainly through close personal contact (such as when people are within 6 feet of one another) and through the respiratory droplets of someone infected with COVID-19.  Aerosol transmission is also likely, but the relative contribution of these smaller respiratory particles is not completely understood. While less common, spreading can also occur when people touch contaminated objects or surfaces and then their faces, eyes, or mouth. 

Transmission of COVID-19

- smoking
- high BMI
- old age
- congregate housing
- environmental conditions
- Immune system conditions

Risk Factors For COVID-19

We can explore factors that affect the uptake of established adult vaccinations to inform efforts of COVID-19 vaccine acceptance. 

- Social Factors 
- Knowledge, Attitudes, and Beliefs
- Racial Factors
- Age

COVID-19 Vaccination Uptake

Contact tracing is used by health departments to prevent the spread of infectious disease. In general, contact tracing involves identifying people who have an infectious disease (cases) and people who they came in contact with (contacts) and working with them to interrupt disease spread. This includes asking people to isolate and their contacts to quarantine at home voluntarily. Contacts are also asked to monitor their symptoms daily, e.g., temperature checks, self-assessments based on common symptoms, and to get tested if any symptoms develop during their isolation.

What is Contact Tracing?

- Time-consuming to self-judge many rapidly released papers
- Difficult to efficiently inform the research community about inappropriate results/findings
- Repetition and contradiction
- Cognitive overload and determining the novelty of a new study
- Published papers are static and don't get updated dynamically
- Difficult for multidisciplinary research collaboration 
- The increased role of preprint servers in COVID-19 research
- Marketing and subscription fees of journals
- Personal ambitions and carrier incentives
- Even the papers published journals are not completely flawless when the time is the essence.
- Difficulty informing the public


Current Barriers Related to COVID-19 Collaborative Research

Many countries are using social media as a way to guide the general public through this pandemic. These forums (such as WhatsApp in Singapore) can help the government provide easily accessible updates and guidelines in each stage of the virus as it impacts society. 

Social Media and COVID-19

This can be done via contact tracing as people adapt to the "new normal".  This allows  clinical personnel to recognize infection hotspots and notify personnel of of possible new cases. This method is used to slow down and the pandemic and plauteau the curve.

Digital Monitoring

Big data is a field that analyze data sets that are too large or complex to be dealt with by traditional data-processing application software or manpower. In the pandemic of Covid-19, many countries have turned to this field to minimize the impact of the pandemic by analyzing and evaluating the possibility of certain people to be infected. Hospitals and care facilities can then be alerted beforehand, and the likelihood of an undetected outbreak is reduced.
