Post-COVID - How safe are you after COVID?

After infection, your body produces natural immunity against the causative pathogen, be it a bacterium or virus. This persists as memory B cells, a type of white blood cell that can be quickly activated to produce antibodies against the pathogen should it infect you again and prevents subsequent infections from causing as much damage and illness. This is something we have covered before and is the underlying mechanism for vaccines and herd immunity.

We are trying to prevent people from catching COVID, as it has the potential to cause significant damage to a large number of your body’s organ system, including long term damage to the lungs and heart that we are still trying to understand. But if you’ve caught COVID, does this mean you cannot catch it again?

A preprint report from Public Health England’s Siren study looked at 20,787 healthcare workers who were regularly tested between June and November 2020. It found 44 reinfections and 409 new infections, equating to an 83% rate of protection from reinfection. This appears to last for at least 5 months from first becoming sick. However, despite having antibodies against the virus, the viral load in these patients is still high enough to infect others.

The implications of this are clear to see. Even if you have had the virus, it is imperative that you continue to follow public health measures dictated by your country’s health department. Masks, washing hands, social distancing, and following lockdown rules depending on where you live. This is especially important when interacting with potentially vulnerable people, such as the elderly or immunocompromised.

You may still be carrying the virus asymptomatically, and in the vulnerable population being infected by COVID-19 can be potentially lethal. There is still not enough data to tell us whether this is also true for people who are vaccinated, but as rates of vaccination increase, future studies will be able to give us this information.

Teen Mental Health – Signs Parents Must Never Ignore

Teenage years are a time of transformation—emotionally, physically, and mentally. While moodiness and rebellion may seem like part of the package, sometimes these behaviors can hide serious mental health issues.

Today, more teenagers are struggling with anxiety, depression, stress, and even thoughts of self-harm—but many go unnoticed because the signs are subtle.

As a parent or guardian, it’s crucial to know the early signs of mental health problems in teens. Let’s explore the red flags you should never ignore and how you can help your child feel supported and heard.

 

Why Teen Mental Health Matters More Than Ever

In India and around the world, teen mental health issues are on the rise due to:

  • Academic pressure
     

  • Social media stress
     

  • Body image concerns
     

  • Bullying or peer pressure
     

  • Family conflicts
     

  • Hormonal changes
     

Ignoring early signs can lead to worsening conditions or even risky behavior. Early action is the key to prevention and healing.

 

5 Warning Signs of Teen Mental Health Issues

 

1. Withdrawal from Family and Friends

If your once-social teen starts avoiding friends, skipping family dinners, or isolating in their room more than usual—it could be a sign of depression or anxiety.

What to watch for:

  • Saying "I’m fine" but acting distant
     

  • Losing interest in favorite activities
     

  • Avoiding calls or texts from friends
     

 

2. Sudden Drop in Academic Performance

Stress, low motivation, or emotional exhaustion often lead to a dip in school performance. If your child suddenly starts failing or avoids school altogether, take it seriously.

What to watch for:

  • Skipping homework or classes
     

  • Teachers reporting attention issues
     

  • Saying "What’s the point?" or "I don’t care anymore"
     

 

3. Changes in Eating or Sleeping Habits

Teen depression often changes daily habits. Some teens may sleep or eat too much, while others may lose their appetite and suffer insomnia.

What to watch for:

  • Skipping meals or binge eating
     

  • Staying up all night
     

  • Always feeling tired
     

 

4. Talk of Hopelessness or Self-Harm

If your teen talks about feeling worthless, says things like “No one cares” or shows an interest in self-harm—it’s a serious red flag.

What to watch for:

  • Negative self-talk
     

  • Writing or drawing about death
     

  • Wearing long sleeves to hide cuts
     

Tip: If you hear even a hint of suicidal thoughts, seek professional help immediately.

 

5. Unexplained Aches and Pains

Sometimes mental health problems appear as physical complaints, especially in teens who struggle to express emotions.

What to watch for:

  • Frequent stomach aches, headaches, or nausea
     

  • No clear medical cause
     

  • Always feeling “sick” before school or social events
     

 

How to Support Your Teen

As a parent, your role is not to fix everything but to listen and support. Here’s how:

  • Create a safe space: Let your teen know they can talk without judgment
     

  • Ask open-ended questions like:
    “How have you been feeling lately?”
    “Do you want to talk or just need someone to listen?”
     

  • Avoid dismissing their emotions with phrases like:
    “You’ll get over it” or “It’s just a phase”
     

  • Encourage healthy routines:
    Regular sleep, a balanced diet, physical activity, and tech breaks
     

 

When to Seek Professional Help

Call a psychologist, counselor, or pediatrician if you notice:

  • Signs persist for more than 2–3 weeks
     

  • Risky behavior like substance use, aggression, or self-harm
     

  • Extreme withdrawal or refusal to attend school
     

  • Talk of suicide or self-hatred
     

 

Useful Health Checks for Teens (Available at SecondMedic.com)

Mental health issues can also be connected to physical imbalances. Consider these lab tests (via Thyrocare):

Thyroid Profile

Hypothyroidism or hyperthyroidism can affect mood and energy.

Vitamin D Test

Low vitamin D is linked to fatigue, depression, and anxiety.

CBC (Complete Blood Count)

To rule out anemia or infections that might affect mood or focus.

CRP Test (C-Reactive Protein)

Detects inflammation, which can also impact mental well-being.

These tests are easily bookable online with home sample collection and fast results.

 

Conclusion

As a parent, you play a key role in recognizing early warning signs and guiding your teen to emotional well-being. What may look like rebellion, laziness, or "drama" could actually be a silent cry for help.

Stay present. Stay open. And most importantly—act early.

If you're unsure about what’s normal and what’s not, just remember this: Teen mental health – signs parents must never ignore could be the first step to saving a life.
