· On Friday FDA announced an emergency authorization of a Roche Holding AG test that can screen patients much faster than all existing options.

· The biggest impact of these tests would be that it would help catch up on the all the tests which are on queue currently.

· What very few have realized that our inability to test enough people fast enough has led to an outbreak that is likely to spin out of control in the weeks to come. If that happens then we won’t be able to contain things any time soon.

· More than lab tests we need “serologic tests” and “on-site diagnostics” which can play a crucial role in helping to better estimate the size of the problem (outbreak) and exercise necessary control to prevent the spread.

· Serologic diagnostics allow extensive testing of samples from people who aren’t confirmed COVID-19 cases.

· The best thing is that If people have been exposed and have developed antibodies against the virus, such tests will let health officials in frontline know much faster.

· This is invaluable information in the fight against a disease that is mild or asymptomatic in many people.

· It will bring some key KPIs to limelight in addition to giving a better sense of how many cases we’re missing and COVID-19’s true fatality rate, it could also identify areas where it is spreading more quietly and help direct needed response.

· Centres for Disease Control Director Robert Redfield recently told a Congressional committee that his agency has two tests of this type in development.

· This fast deployment is critical piece around the globe as there simply isn’t any reliable information on where we stand at any time and where the disease is and how many people have it.

· Another important step would involve moving testing capabilities out of the lab and into doctors’ offices.

· Ideally, providers should be able to order and run tests rapidly on site similar to the flu instead of sending them off to an overtaxed lab and lowering risk of infection

· An accurate and quick test of this type would mean that fewer people are left hanging in limbo about their actual infection status, expediting isolation, monitoring, and treatment efforts.

· People could be diagnosed in a far broader array of settings, lowering the risk of further spread of infection and keeping them out of hospitals that could spend more of their time totally focused to severe cases.

· A wider range of diagnostics would enable more targeted monitoring and reduce the need for blanket travel bans and other economically harmful containment measures. We hope that all support would get these tests approved and distributed quickly.

So in summary the approach is in a good direction and agility around diagnosis will get us ahead of things while we’re still only in the early stages of this outbreak.

How Cold Weather Affects Health: Understanding Winter’s Impact on the Body

How Cold Weather Affects Health: Understanding Winter’s Impact on the Body

Seasonal changes influence human health more than most people realise. Cold weather, in particular, places unique stress on the body and can worsen existing health conditions while increasing susceptibility to new illnesses. Understanding how cold weather affects health is essential for preventing seasonal complications and maintaining wellbeing during winter months.

In India, winter-related health issues vary by region but commonly include respiratory infections, cardiovascular strain and joint discomfort. According to the Indian Council of Medical Research (ICMR) and World Health Organization (WHO), cold exposure is associated with increased morbidity, especially among older adults and people with chronic conditions.

 

Why Cold Weather Impacts the Body

The human body works constantly to maintain core temperature. In cold environments:

  • blood vessels constrict to conserve heat
     

  • energy expenditure increases
     

  • immune responses may weaken
     

  • organs work harder to maintain balance
     

These adaptations, while protective, also create health vulnerabilities.

 

Increased Risk of Infections

Weakened Immune Response

Cold weather can suppress immune function, making it harder for the body to fight infections.

Factors contributing to winter infections include:

  • reduced vitamin D due to less sunlight
     

  • dry air affecting mucosal defenses
     

  • closer indoor contact
     

Common winter infections include colds, flu and respiratory illnesses.

 

Respiratory Health Problems

Cold air irritates the respiratory tract.

This can lead to:

  • worsening asthma symptoms
     

  • bronchitis flare-ups
     

  • increased cough and breathlessness
     

WHO reports higher hospital admissions for respiratory illnesses during colder months.

 

Impact on Heart Health

Cold temperatures affect cardiovascular function.

Blood Vessel Constriction

Cold causes blood vessels to narrow, increasing:

  • blood pressure
     

  • heart workload
     

This raises the risk of:

  • heart attacks
     

  • strokes
     

People with existing heart disease are particularly vulnerable.

 

Joint and Muscle Pain

Cold weather affects musculoskeletal health.

Common complaints include:

  • joint stiffness
     

  • muscle aches
     

  • worsening arthritis pain
     

Lower temperatures reduce joint lubrication and increase sensitivity to pain.

 

Metabolic and Weight Changes

Winter often leads to:

  • reduced physical activity
     

  • increased calorie intake
     

  • metabolic slowdown
     

These changes contribute to weight gain and worsen metabolic conditions such as diabetes.

 

Skin and Hydration Issues

Cold air holds less moisture.

This leads to:

  • dry skin
     

  • cracked lips
     

  • worsening eczema
     

Dehydration is also common as thirst perception reduces in cold weather.

 

Mental Health Effects

Seasonal changes can influence mental wellbeing.

Cold weather is associated with:

  • low mood
     

  • reduced motivation
     

  • seasonal affective symptoms
     

Limited sunlight affects circadian rhythm and serotonin levels.

 

Cold Weather and Older Adults

Elderly individuals face higher risks due to:

  • reduced temperature regulation
     

  • weaker immunity
     

  • existing chronic conditions
     

Winter-related complications are a significant cause of hospitalisation in older populations.

 

Why Chronic Diseases Worsen in Winter

Conditions such as:

  • hypertension
     

  • arthritis
     

  • asthma
     

  • diabetes
     

often worsen due to reduced activity, stress on organs and infection risk.

 

Preventive Strategies for Winter Health

Maintain Body Warmth

Layered clothing and warm environments reduce cold stress.

 

Support Immunity

Adequate nutrition, vitamin intake and sleep strengthen immune defences.

 

Stay Physically Active

Indoor exercises and regular movement prevent stiffness and metabolic decline.

 

Manage Chronic Conditions

Regular monitoring and medication adherence are critical during winter.

 

Hydration and Skin Care

Drinking fluids and using moisturisers prevent dehydration and skin damage.

 

Role of Preventive Healthcare

Preventive healthcare helps:

  • identify seasonal risk factors
     

  • adjust treatment plans
     

  • prevent winter complications
     

NITI Aayog highlights seasonal preparedness as an important public health strategy.

When to Seek Medical Help

Medical attention is necessary if:

  • infections persist or worsen
     

  • chest pain or breathlessness occurs
     

  • joint pain limits mobility
     

  • mental health symptoms interfere with daily life
     

Early care prevents serious outcomes.

 

Long-Term Impact of Ignoring Winter Health Risks

Ignoring cold weather effects may lead to:

  • severe infections
     

  • cardiovascular events
     

  • chronic pain progression
     

  • reduced quality of life
     

Seasonal awareness plays a critical role in long-term health.

 

Conclusion

Understanding how cold weather affects health allows individuals to take timely preventive measures. Winter increases the risk of infections, heart strain, respiratory problems, joint pain and mental health challenges. With proper warmth, nutrition, activity and preventive healthcare, most cold-related health issues are manageable and preventable. Seasonal care is not optional—it is essential for protecting health and wellbeing throughout the colder months.
