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.

Neurobion Forte: Benefits for Nerve Health and Vitamin B Deficiency

Vitamin deficiencies are a common but often overlooked health issue. Among them, vitamin B deficiency is particularly significant because of its direct impact on nerve function, energy metabolism and overall neurological health. Neurobion Forte is a widely used vitamin B-complex supplement designed to address these deficiencies and support nerve health.

Understanding how Neurobion Forte works and when it is beneficial helps individuals make informed decisions about their nutritional and neurological wellbeing.

What Is Neurobion Forte?

Neurobion Forte is a combination supplement containing essential B vitamins, primarily:

vitamin B1 (thiamine)
vitamin B6 (pyridoxine)
vitamin B12 (cobalamin)

These vitamins play a vital role in nerve signal transmission, energy production and maintenance of the nervous system.

Why Vitamin B Is Essential for Nerve Health

B vitamins are crucial for:

nerve impulse transmission
myelin sheath formation
energy metabolism in nerve cells

Deficiency can impair nerve function, leading to discomfort and neurological symptoms.

Common Causes of Vitamin B Deficiency

Vitamin B deficiency may occur due to:

inadequate dietary intake
poor absorption
chronic illnesses
long-term medication use
alcohol misuse

Vegetarians and elderly individuals are particularly at risk of vitamin B12 deficiency.

Symptoms of Vitamin B Deficiency

Early symptoms may include:

fatigue
weakness
numbness or tingling in hands and feet
poor concentration

If untreated, deficiency may progress to more serious neurological problems.

How Neurobion Forte Supports Nerve Health

Supports Nerve Repair

Vitamin B12 contributes to nerve regeneration and maintenance of nerve fibres.

Improves Nerve Signal Transmission

Vitamin B1 supports proper nerve impulse conduction.

Reduces Nerve Irritation

Vitamin B6 helps regulate neurotransmitter synthesis, reducing nerve-related discomfort.

Supports Energy Metabolism

B vitamins help convert food into energy, supporting overall nerve and muscle function.

Role of Neurobion Forte in Nerve Pain

Nerve pain caused by vitamin deficiency may present as:

burning sensation
tingling
numbness
shooting pain

In such cases, correcting the deficiency through supplementation may help relieve symptoms over time.

Conditions Where Neurobion Forte Is Commonly Used

Neurobion Forte may be prescribed or recommended in cases such as:

peripheral neuropathy
diabetic neuropathy (as supportive care)
nutritional deficiency-related nerve symptoms
general weakness associated with vitamin B deficiency

It is not a painkiller but supports underlying nutritional correction.

Importance of Medical Guidance

While vitamin supplements are widely available, inappropriate or excessive use may cause side effects.

Medical guidance ensures:

correct diagnosis
appropriate dosage
monitoring of response

Self-medication should be avoided, especially for long-term use.

Diet and Vitamin B Intake

Dietary sources of B vitamins include:

whole grains
legumes
dairy products
eggs
meat and fish

Balanced nutrition remains the foundation of vitamin sufficiency.

Who May Benefit Most from Neurobion Forte?

Individuals who may benefit include:

those with confirmed vitamin B deficiency
people with nerve-related symptoms
elderly individuals with poor nutrient absorption
individuals with restricted diets

Supplementation should complement dietary improvement.

Possible Side Effects and Precautions

When taken as advised, Neurobion Forte is generally well tolerated.

However:

excessive vitamin B6 intake may cause nerve symptoms
allergic reactions are rare but possible

Always follow professional advice.

How Long Does It Take to See Benefits?

Improvement depends on:

severity of deficiency
duration of symptoms
individual health status

Some people notice symptom improvement within weeks, while others require longer support.

Neurobion Forte and Overall Wellbeing

Correcting vitamin B deficiency supports:

nerve health
energy levels
cognitive function
overall vitality

Supplementation is most effective when combined with healthy lifestyle habits.

Conclusion

Neurobion Forte plays an important role in managing vitamin B deficiency and supporting nerve health. By supplying essential B vitamins, it helps restore nerve function, reduce deficiency-related symptoms and improve overall neurological wellbeing. While it can be highly beneficial when deficiency is present, its use should always be guided by medical advice to ensure safety and effectiveness. Balanced nutrition, early diagnosis and appropriate supplementation together form the foundation of healthy nerve function.
