COVID: A Reminder To Stay Safe

COVID: A reminder to stay safe

As we approach the second wave of COVID, we need to remain vigilant with our actions to prevent the spread of the virus. We are continuously reminded about wearing a mask in public, maintaining socially distant, and not engaging in risky behavior such as large gatherings. But today we will focus on other forms of transmission. COVID is primarily transmitted by airborne droplets, but spreading the infection through infected surfaces is still feasible. Here we will look at three articles that investigate this mode of transmission.

SARS-COV-2 Survives for 28 days on surfaces

This study by Australian scientists has found that SARS-CoV-2 can survive on surfaces for up to 28 days. The team investigated using the same amounts of virus found on infected individuals, interacting with surfaces such as cotton, paper, stainless steel, glass, and vinyl. Such materials were chosen as they represent commonly touched objects such as mobile phones, ATMs, supermarket checkout regions, items that may not be cleaned regularly enough. Previous research showed the virus could be detected in aerosols for up to three hours, and on plastic and stainless steel surfaces for up to three days.

This study found the virus may survive as long as a week on most surfaces, with enough potency to re-infect. Even after two weeks, there were still plenty of detectable viruses. On other surfaces such as banknotes, the virus could survive as long as a month. The survival of the virus is also potentiated by colder temperatures. The virus is far less likely to survive at 30C than at 6 C, a worrying finding for countries currently approaching winter.

Survival of SARS-CoV 2 on the human skin

We know our skin is host to millions of different bacteria and viruses, but the conditions created by the body alongside the degree of microbial competition actually makes it quite a hostile environment for pathogenic microbes. Hirose et al looked to investigate how well the SARS-CoV-2 virus survives on human skin, using a model. They found that SARS-CoV-2 and the influenza A virus were destroyed more quickly on the skin than other surfaces such as steel, glass, and plastic. However, COVID lasted over 4x longer on skin compared to Influenza A (9 hours vs 1.8 hours).

More importantly, ethanol compounds were found to inactivate SARS-CoV-2 within 15 seconds on human skin. This highlights the importance of regular hand washing, even if with alcohol gel. Taking this in mind, it is useful to keep small bottles of alcohol gel on a person when traveling in public and using it regularly. After all, if you are touching door handles and other items that hundreds of other people may have touched before you, potentially with poor hygiene, it is safer to regularly disinfect.

Low risk of COVID transmission by fomites in real life conditions

Having taken these studies into account, it is quite difficult to quantifiably measure transmission from surface to a person. Knowledge of this transmissibility is quite important, especially to those working in a hospital environment. A review by Mondelli et al published in the prestigious journal The Lancet (Infectious Disease) describes two sequential studies to looking at the possibility of contamination of surfaces in an infectious disease ward of a major Italian hospital, and also whether risk of transmission was higher in emergency rooms and sub-intensive care wards.

These studies found there were very few surfaces in the hospital through which positive swabs could be taken, suggesting contamination was low. Of course the hospitals were running standard cleaning procedures, with regular wipedowns of commonly toughed objects. This again highlights the importance of maintaining hygiene, and how adequate cleanliness can significantly reduce the risk of infection.

Monthly Health Survey via SecondMedic App: A Smarter Approach to Preventive Healthcare

Healthcare is gradually shifting from reactive treatment to proactive prevention. Traditional health models rely heavily on annual checkups or medical visits only after symptoms become severe. However, many chronic and lifestyle-related conditions develop silently over time. The Monthly Health Survey via the SecondMedic App addresses this gap by enabling continuous health monitoring and early risk identification.

According to the Indian Council of Medical Research (ICMR) and NITI Aayog, early detection and preventive care are critical to reducing the growing burden of non-communicable diseases in India. Digital health tools play a key role in achieving this shift.

What Is the Monthly Health Survey?

The Monthly Health Survey is a structured digital questionnaire delivered through the SecondMedic App. It captures key health indicators such as:

recurring symptoms
lifestyle habits
stress and sleep patterns
nutrition and activity levels
chronic condition markers

By repeating the survey monthly, subtle health trends become visible.

Why Monthly Health Tracking Matters

Annual Checkups Miss Gradual Changes

Many health issues develop slowly. Annual tests may appear normal while symptoms quietly progress between visits.

Monthly surveys:

detect early warning signs
capture symptom patterns
identify lifestyle-related risks

Health Is Dynamic, Not Static

Stress, sleep, diet and activity fluctuate monthly. Regular tracking reflects real-life health variation more accurately than isolated tests.

How the Monthly Health Survey Works

Each month, users answer a guided set of questions related to:

physical symptoms
mental wellbeing
lifestyle behaviours
known medical conditions

The app analyses responses to highlight:

risk trends
symptom persistence
areas needing attention

This structured approach simplifies health awareness.

Key Health Areas Covered

Symptom Monitoring

Persistent fatigue, headaches, breathlessness or digestive issues are tracked across months to identify patterns.

Lifestyle Risk Factors

The survey captures:

sedentary behaviour
sleep quality
stress levels
dietary habits

These factors strongly influence long-term health outcomes.

Chronic Disease Indicators

For individuals with diabetes, hypertension or thyroid conditions, monthly monitoring supports better disease control and early escalation.

Role in Preventive Healthcare

Preventive healthcare focuses on stopping disease before complications arise.

Monthly health surveys support prevention by:

identifying risks early
prompting timely consultations
supporting lifestyle modification
reducing emergency care needs

WHO and NITI Aayog both highlight digital monitoring as a cornerstone of preventive health systems.

Benefits for Individuals

Early Awareness

Users become aware of health changes before symptoms become severe.

Empowered Decision-Making

Access to regular health insights encourages proactive lifestyle choices.

Reduced Anxiety

Structured tracking reduces uncertainty and fear about unexplained symptoms.

Better Doctor Consultations

Survey data provides doctors with a clearer health history, improving consultation quality.

Benefits for Chronic Care Management

For chronic conditions, consistency is key.

Monthly surveys help:

track symptom control
identify early deterioration
support medication adherence
reduce complications

This continuous loop improves long-term outcomes.

Data-Driven Personalised Care

The survey supports personalised care by:

tailoring recommendations
prioritising high-risk users
guiding preventive interventions

This approach moves healthcare from generic advice to individualised guidance.

Privacy and Responsible Use

Health data is sensitive.

The survey framework is designed to:

collect only relevant information
support medical decision-making
maintain confidentiality

Responsible data use builds trust and long-term engagement.

Why Digital Surveys Are Effective in India

India’s healthcare challenges include:

large population
limited access to preventive care
high lifestyle disease burden

Digital surveys overcome barriers by:

being accessible anywhere
requiring minimal time
enabling large-scale preventive monitoring

This scalability makes them highly impactful.

Integration with Broader Health Ecosystems

Monthly health surveys work best when integrated with:

medical consultations
diagnostic services
preventive checkups
digital health records

Integration ensures continuity of care.

Long-Term Impact on Healthcare Outcomes

Over time, regular health tracking leads to:

earlier diagnoses
reduced hospitalisations
better chronic disease control
lower healthcare costs
improved quality of life

Lancet studies show that continuous monitoring significantly improves preventive outcomes.

Who Should Use a Monthly Health Survey?

adults over 30
individuals with chronic conditions
people with high-stress lifestyles
those focusing on preventive health
corporate wellness participants

Proactive monitoring benefits all age groups.

Conclusion

The Monthly Health Survey via the SecondMedic App represents a modern, preventive approach to healthcare. By capturing health trends regularly rather than annually, it empowers individuals to act early, supports doctors with better insights and reduces the burden of advanced disease. In an era where prevention is the most effective medicine, monthly health surveys transform awareness into action and data into healthier lives.
