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.

Diabetes Symptoms in Men: Early Warning Signs You Should Not Ignore

Diabetes is one of the fastest-growing health challenges worldwide, and men are particularly vulnerable to its long-term complications. In India, the burden of diabetes has increased sharply over the past two decades, driven by lifestyle changes, sedentary habits and dietary patterns. Despite this, many men remain unaware of early diabetes symptoms or delay medical consultation until complications develop.

Understanding diabetes symptoms in men is essential for early diagnosis, effective management and prevention of serious health consequences.

What Is Diabetes?

Diabetes is a chronic metabolic disorder characterised by high blood sugar levels due to:

insufficient insulin production
ineffective insulin action
or both

The most common form affecting men is type 2 diabetes, which is strongly linked to lifestyle factors.

Why Men Are at Higher Risk

Several factors increase diabetes risk in men:

higher abdominal fat accumulation
smoking and alcohol consumption
irregular eating patterns
work-related stress
lower healthcare-seeking behaviour

According to Indian Council of Medical Research data, a significant proportion of men remain undiagnosed until advanced stages.

Early Diabetes Symptoms in Men

Frequent Urination

Excess sugar in the blood causes kidneys to work harder, leading to increased urination, especially at night.

Excessive Thirst

Frequent urination leads to dehydration, causing constant thirst.

Fatigue and Weakness

Cells cannot utilise glucose efficiently, resulting in low energy levels and persistent tiredness.

Unexplained Weight Changes

Men may experience unexplained weight loss despite normal or increased appetite.

Increased Hunger

Insulin resistance prevents glucose from entering cells, triggering frequent hunger.

Diabetes Symptoms Unique or Commonly Seen in Men

Erectile Dysfunction

Diabetes damages blood vessels and nerves, leading to erectile dysfunction.

Studies show a strong association between diabetes and male sexual health problems.

Reduced Testosterone Levels

Men with diabetes often have lower testosterone, affecting libido, muscle mass and mood.

Decreased Muscle Strength

Poor glucose utilisation affects muscle health and physical stamina.

Skin and Infection-Related Symptoms

Slow-Healing Wounds

High blood sugar impairs wound healing, increasing infection risk.

Frequent Infections

Men with diabetes are more prone to:

skin infections
urinary tract infections
fungal infections

Vision and Nerve Symptoms

Blurred Vision

Fluctuating blood sugar affects eye lenses, causing blurred vision.

Tingling or Numbness

Nerve damage, known as diabetic neuropathy, causes tingling or numbness in hands and feet.

Why Diabetes Symptoms Are Often Ignored by Men

Many men dismiss symptoms as:

work-related fatigue
ageing
stress

This delay increases the risk of complications.

Long-Term Complications of Untreated Diabetes

If untreated, diabetes can lead to:

heart disease
kidney failure
nerve damage
vision loss
sexual dysfunction

According to WHO and Lancet studies, early detection significantly reduces complication risk.

Importance of Early Diagnosis

Early diagnosis allows:

better blood sugar control
lifestyle modification
prevention of organ damage

Routine screening is crucial, even in the absence of symptoms.

When Should Men Get Tested?

Men should consider testing if they:

are over 30 years old
have a family history of diabetes
are overweight
have a sedentary lifestyle
experience any warning signs

Annual screening is recommended for at-risk individuals.

Managing Diabetes After Diagnosis

Effective management includes:

healthy diet
regular physical activity
weight control
stress management
medical treatment as advised

Early management improves quality of life.

Role of Preventive Healthcare

Preventive healthcare focuses on:

early screening
lifestyle intervention
regular follow-up

According to NITI Aayog, preventive strategies are essential to control India’s diabetes burden.

Mental Health and Diabetes in Men

Diabetes can affect mental wellbeing, leading to:

stress
anxiety
depression

Addressing emotional health improves diabetes outcomes.

Breaking the Stigma Around Men’s Health

Men often avoid seeking help due to stigma.

Promoting awareness helps:

normalise health conversations
encourage timely medical care
reduce preventable complications

Conclusion

Diabetes symptoms in men often develop gradually and may go unnoticed for years. Frequent urination, fatigue, unexplained weight changes and sexual health issues should never be ignored. Early diagnosis and timely management significantly reduce the risk of serious complications and improve long-term health outcomes. Awareness, routine screening and proactive healthcare are essential steps for men to protect their health and wellbeing in an era of rising lifestyle diseases.
