What to do to keep yourself and others safe from COVID-19

Maintain at least a 1-meter distance between yourself and others to reduce your risk of infection when they cough, sneeze or speak. Maintain an even greater distance between yourself and others when indoors. The further away, the better.

Make wearing a mask a normal part of being around other people. The appropriate use, storage, and cleaning or disposal are essential to make masks as effective as possible.

  • Here are the basics of how to wear a mask:

Clean your hands before you put your mask on, as well as before and after you take it off, and after you touch it at any time.
Make sure it covers both your nose, mouth, and chin.

When you take off a mask, store it in a clean plastic bag, and every day either wash it if it’s a fabric mask or dispose of a medical mask in a trash bin.
Don’t use masks with valves.

For specifics on what type of mask to wear and when read our Q&A and watch our videos. There is also a Q&A focused on masks and children.

  • How to make your environment safer

Avoid the 3Cs: spaces that are closed, crowded, or involve close contact.
Outbreaks have been reported in restaurants, choir practices, fitness classes, nightclubs, offices, and places of worship where people have gathered, often in crowded indoor settings where they talk loudly, shout, breathe heavily or sing.

The risks of getting COVID-19 are higher in crowded and inadequately ventilated spaces where infected people spend long periods of time together in close proximity. These environments are where the virus appears to spread by respiratory droplets or aerosols more efficiently, so taking precautions is even more important.

Meet people outside. Outdoor gatherings are safer than indoor ones, particularly if indoor spaces are small and without outdoor air coming in.
For more information on how to hold events like family gatherings, children’s football games, and family occasions, read our Q&A on small public gatherings.
Avoid crowded or indoor settings but if you can’t, then take precautions:
Open a window.

WHO has published Q&As on ventilation and air conditioning for both the general public and people who manage public spaces and buildings.
Wear a mask.

  • Don’t forget the basics of good hygiene

Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water. This eliminates germs including viruses that may be on your hands.

Avoid touching your eyes, nose, and mouth. Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose, or mouth. From there, the virus can enter your body and infect you.

Cover your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately into a closed bin and wash your hands. By following good ‘respiratory hygiene’, you protect the people around you from viruses, which cause colds, flu, and COVID-19.
Clean and disinfect surfaces frequently especially those which are regularly touched, such as door handles, faucets, and phone screens.
 

  • What to do if you feel unwell

Know the full range of symptoms of COVID-19. The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include loss of taste or smell, aches, and pains, headache, sore throat, nasal congestion, red eyes, diarrhea, or a skin rash.

Stay home and self-isolate even if you have minor symptoms such as cough, headache, mild fever until you recover. Call your health care provider or hotline for advice. Have someone bring you supplies. If you need to leave your house or have someone near you, wear a medical mask to avoid infecting others.

If you have a fever, cough, and difficulty breathing, seek medical attention immediately. Call by telephone first, if you can, and follow the directions of your local health authority.

The Acne Truth: Why Your Face Keeps Breaking Out (And What Actually Helps)

Description: Discover the real causes of acne and proven prevention methods. Learn what triggers breakouts, which treatments work, and stop wasting money on products that don't help.


Let me tell you about the small fortune I spent trying to cure my acne before I actually understood what caused it.

I tried every trendy solution: charcoal masks (did nothing), "detox" teas (laxatives in disguise), cutting out dairy (helped slightly but wasn't the whole answer), expensive serums promising "clear skin in 7 days" (lies), and that period where I washed my face five times daily because surely cleaner = better, right? (Spoiler: made everything worse).

My skin looked... exactly the same. Sometimes better, sometimes worse, but mostly just consistently broken out despite my desperate attempts and mounting credit card debt from skincare products.

Then I actually talked to a dermatologist who patiently explained that what causes acne is way more complex than "dirty skin" or "eating chocolate," and most of what I'd been doing was either useless or actively counterproductive.

Acne causes and prevention isn't about one magic product or eliminating one food. It's about understanding hormones, genetics, skin biology, and the complex interplay of factors that create those painful bumps you can't help picking at (even though you absolutely should not).

How to prevent acne naturally sounds appealing, but "natural" doesn't automatically mean effective, and some natural remedies are genuinely harmful. Meanwhile, some "chemical" treatments dermatologists prescribe actually work because they're based on science, not marketing.

So let me give you what I wish I'd known before wasting years and money: the real causes of acne, which prevention methods actually have evidence behind them, and how to tell the difference between helpful treatment and expensive snake oil.

Because your skin deserves better than misinformation.

And your wallet deserves better than buying every product TikTok influencers shill.

What Acne Actually Is (The Biology Lesson)

Understanding acne scientifically starts with knowing what's happening under your skin:

The Anatomy of a Pimple

Sebaceous glands: Produce oil (sebum) that lubricates skin and hair.

Hair follicles (pores): Where hair grows, connected to sebaceous glands.

The process:

  1. Sebaceous glands produce sebum
  2. Sebum travels up hair follicle to skin surface
  3. Dead skin cells mix with sebum
  4. Sometimes this mixture clogs the pore
  5. Bacteria (specifically C. acnes) feed on trapped sebum
  6. Inflammation occurs
  7. You get a pimple

That's it: It's not punishment for eating pizza or evidence you're dirty. It's biological process gone slightly wrong.

Types of Acne

Non-inflammatory:

  • Blackheads: Open comedones, oxidized sebum makes them dark
  • Whiteheads: Closed comedones, trapped sebum under skin

Inflammatory:

  • Papules: Small red bumps, inflamed but no pus
  • Pustules: Red bumps with white pus-filled center
  • Nodules: Large, painful bumps deep under skin
  • Cysts: Severe, pus-filled, painful, deep, scarring

Severity matters: Treatment for occasional whiteheads differs from treatment for cystic acne.

The Real Causes of Acne

What actually causes breakouts:

1. Hormones (The Primary Culprit)

Androgens (testosterone, DHEA): Increase during puberty, menstrual cycles, pregnancy, stress.

What they do:

  • Stimulate sebaceous glands to produce more oil
  • Increase skin cell production
  • More oil + more dead cells = more clogged pores

Why teenagers get acne: Puberty floods body with androgens. Sebaceous glands go into overdrive.

Why adults get acne: Hormonal fluctuations continue. Women especially affected by menstrual cycles, pregnancy, PCOS, perimenopause.

This is why: Topical treatments alone often aren't enough. Hormonal acne needs hormonal solutions.

2. Genetics (The Unfair Advantage/Disadvantage)

Your DNA determines:

  • How much sebum your glands produce
  • How easily your pores clog
  • How inflammatory your immune response is
  • Likelihood of scarring

If both parents had acne: You're highly likely to have it too.

Not your fault: You didn't cause it by eating poorly or not washing enough. Genetics loaded the gun.

The good news: Even genetic acne responds to treatment. You're not doomed.

3. Excess Sebum Production

Oily skin and acne correlation: More oil = more potential for clogged pores.

But: Not everyone with oily skin has acne. And not everyone with acne has oily skin.

Factors increasing sebum:

  • Hormones (see above)
  • Climate (heat and humidity increase production)
  • Over-washing (strips oil, skin compensates by producing more)
  • Some medications

You can't eliminate sebum: It's necessary for skin health. Goal is balance, not elimination.

4. Clogged Pores (Dead Skin Cells)

Skin sheds constantly: Dead cells normally shed without issue.

The problem: Sometimes dead cells stick together, mix with sebum, form plug.

Why this happens:

  • Excess sebum makes cells sticky
  • Abnormal keratinization (skin cells don't shed properly)
  • Genetics (some people's cells just clump more)

Exfoliation helps: Removing dead cells before they clog pores. But over-exfoliation causes problems (covered in mistakes section).

5. Bacteria (Cutibacterium acnes, formerly Propionibacterium acnes)

It lives on everyone's skin: Not an infection you "caught."

Normally harmless: When pores aren't clogged, it's fine.

The problem: Trapped in clogged pore with sebum (its food), it multiplies rapidly.

Immune response: Your body attacks bacteria, causing inflammation, redness, pus.

Why antibiotics sometimes work: They kill bacteria, reducing inflammation.

The limitation: Bacteria isn't the root cause. It's opportunistic. Treat underlying causes (excess oil, clogged pores) or bacteria returns when antibiotics stop.

Here are the foods you must eat to recover faster from dengue

Monsoon is here, and that means it’s the time when mosquitoes cause all kinds of diseases!  Dengue and malaria are two of the most common diseases that wreak havoc. Unfortunately, those who suffer from dengue experience gut-wrenching pain, high fever, and weakness. In the worst cases, the recovery takes months. But you will be glad to know that there is a specific dengue diet, which can help recover faster.

 

  • Papaya leaves

If someone has suffered from dengue at home, you must have heard of papaya leaves being advised to them. That’s because with dengue, our platelet count drops drastically, and papaya leaves can help in bringing that back to normal. They can be consumed in the form of juice. Interestingly, they also help in boosting immunity, so that you recover faster from dengue.
