Important Questions About Zika Virus Answered
Important Questions About Zika Virus Answered
Q: What is Zika?
A: Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito (Aedes aegypti and Aedes albopictus). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms. However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects.
Q: How do people get infected with Zika?
A: Zika is spread to people primarily through the bite of an infected Aedes species mosquito (Aedes aegypti and Aedes albopictus). A pregnant woman can pass Zika to her fetus during pregnancy or around the time of birth. Also, a person with Zika can pass it to his or her sex partners. We encourage people who have traveled to or live in places with risk of Zika to protect themselves by preventing mosquito bites and sexual transmission of Zika.
Q: What health problems can result from getting Zika?
A: Many people infected with Zika will have no symptoms or mild symptoms that last several days to a week. However, Zika infection during pregnancy can cause a serious birth defect called microcephaly and other severe fetal brain defects. Current research suggests that Guillain-Barre syndrome (GBS), an uncommon sickness of the nervous system, is strongly associated with Zika; however, only a small proportion of people with recent Zika virus infection get GBS.
Once someone has been infected with Zika, it’s very likely they’ll be protected from future infections. There is no evidence that past Zika infection poses an increased risk of birth defects in future pregnancies.
Q: Should pregnant women travel to areas with a risk of Zika?
A: Pregnant women should NOT travel to areas with Zika outbreaks. Before traveling to other areas with the current or past spread of Zika, pregnant women should discuss their travel plans with a doctor. Travelers who go to places with outbreaks or past or current spread can be infected with Zika. Zika infection during pregnancy can cause microcephaly and other severe brain defects.
Q: What can people do to prevent Zika?
A: The best way to prevent Zika is to protect yourself and your family from mosquito bites:
Use registered insect repellents Wear long-sleeved shirts and long pants
Sleep under a mosquito bed net if air-conditioned or screened rooms are not available or if sleeping outdoors.
Zika can be spread by a person infected with Zika to his or her sex partners. Condoms can reduce the chance of getting Zika from sex. Condoms include male and female condoms. To be effective, condoms should be used from start to finish, every time during vaginal, anal, and oral sex and the sharing of sex toys. Not having sex eliminates the risk of getting Zika from sex. Pregnant couples with a partner who traveled to or lives in an area with risk of Zika should use condoms every time they have sex or not have sex during the pregnancy.
Q: What are the symptoms of Zika virus disease?
A: The most common symptoms of Zika virus disease are fever, rash, headache, joint pain, red eyes, and muscle pain. Many people infected with Zika won’t have symptoms or will have mild symptoms, which can last for several days to a week.
Q: How is Zika diagnosed?
A: To diagnose Zika, your doctor will ask you about recent travel and symptoms you may have and collect blood or urine to test for Zika or similar viruses.
Q: Can someone who returned from an area with a risk of Zika get tested for the virus?
A: Zika virus testing is performed at CDC and some state and territorial health departments. See your doctor if you have Zika symptoms and have recently been in an area with a risk of Zika. Your doctor may order tests to look for Zika or similar viruses like dengue and chikungunya.
Q: What should pregnant women who have recently traveled to an area with a risk of Zika do?
A: Pregnant women who have recently traveled to an area with a risk of Zika should talk to their doctor about their travel, even if they don’t feel sick. Pregnant women should see a doctor if they have any Zika symptoms during their trip or after traveling. All pregnant women can protect themselves by avoiding travel to an area with risk of Zika, preventing mosquito bites, and following recommended precautions against getting Zika through sex.
Q: I am not pregnant, but will my future pregnancies be at risk if I am infected with the Zika virus?
A: Currently, there is no evidence that a woman who has recovered from Zika virus infection (the virus has cleared her body) will have Zika-related pregnancy complications in the future. Based on information about similar infections, once a person has been infected with the Zika virus and has cleared the virus from his or her body, he or she is likely to be protected from future Zika infections.
If you’re thinking about having a baby soon and you or your partner live in or traveled to an area with the risk of Zika, talk with your doctor or another healthcare provider. See Women & Their Partners Trying to Become Pregnant.
Q: How should insect repellents be used on children to prevent mosquito bites and the viruses that some mosquitoes can spread?
A: When using insect repellent on your child always follow label instructions. Do not use products containing oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD) on children under 3 years old. Do not apply insect repellent to a child’s hands, eyes, mouth, cuts, or irritated skin. Adults should spray insect repellent onto their hands and then apply it to a child’s face.
Q: What should I do if I am sick, or a family member is sick, with Zika?
A: Many people infected with the Zika virus won’t have symptoms or will only have mild symptoms lasting several days to a week. If you have symptoms of Zika (fever, rash, headache, joint pain, red eyes, or muscle pain) and you live in or recently traveled to an area with risk of Zika, you should see your doctor or healthcare provider and tell him or her about your symptoms and recent travel. There is no specific medicine for Zika, but you can treat the symptoms. If you are diagnosed with Zika, protect those around you by taking steps to prevent mosquito bites and to prevent sexual transmission of Zika. Because Zika can generally be found in the blood during approximately the first week of infection and can be passed to another person through mosquito bites, help prevent others from getting sick by strictly following steps to prevent mosquito bites during the first week of illness.

A. No, Zika virus is not spread through casual contact such as shaking hands or sharing food. The primary modes of transmission are through the bite of an infected Aedes mosquito, sexual contact, and from a pregnant mother to her unborn child. Blood transfusion is a rare mode of transmission, but Zika cannot spread through coughing, sneezing, or touching.
A. If you have symptoms like fever, rash, joint pain, red eyes, or headache and have recently traveled to an area with Zika risk, you should consult your healthcare provider. Your doctor may recommend testing to confirm the presence of the virus. While there is no specific treatment for Zika, managing symptoms with rest, fluids, and pain relievers like acetaminophen is advised. Be sure to take precautions to avoid mosquito bites to prevent spreading the virus to others.
A. Couples should take precautions when planning pregnancy after Zika infection. It is recommended that men wait at least six months after symptoms or exposure, and women wait at least two months. This helps minimize the risk of the virus affecting future pregnancies. Always consult your healthcare provider for personalized guidance based on your circumstances
Vitamin D Deficiency Symptoms: Signs Your Body May Be Lacking Vitamin D
Vitamin D is an essential nutrient that plays a vital role in maintaining strong bones, supporting the immune system and regulating several important functions in the body. Despite its importance, vitamin D deficiency is one of the most common nutritional deficiencies worldwide.
In India, vitamin D deficiency has become increasingly prevalent due to lifestyle factors such as limited sunlight exposure, indoor working environments and dietary habits. According to the Indian Council of Medical Research (ICMR), a significant percentage of the population may have insufficient vitamin D levels.
Recognizing the symptoms of vitamin D deficiency early is important because prolonged deficiency can lead to serious health complications affecting bones, muscles and overall wellbeing.
What Is Vitamin D and Why Is It Important?
Vitamin D is often called the “sunshine vitamin” because the body produces it when the skin is exposed to sunlight. It plays a key role in calcium absorption, which is essential for maintaining healthy bones and teeth.
In addition to bone health, vitamin D supports several important functions including:
immune system regulation
muscle function
inflammation control
hormonal balance
Low levels of vitamin D can disrupt these functions and contribute to various health problems.
Common Symptoms of Vitamin D Deficiency
Vitamin D deficiency can manifest through several symptoms, many of which are often overlooked or mistaken for other health issues.
Persistent Fatigue
Constant tiredness or low energy levels may be one of the earliest signs of vitamin D deficiency. Even after adequate rest, individuals with low vitamin D levels may continue to feel exhausted.
Vitamin D plays a role in cellular energy production, and insufficient levels may contribute to chronic fatigue.
Bone and Back Pain
One of the most well-known effects of vitamin D deficiency is bone discomfort. Vitamin D helps the body absorb calcium, which is essential for maintaining bone strength.
Low vitamin D levels may cause:
bone pain
lower back pain
increased risk of fractures
Persistent bone discomfort should be evaluated by a healthcare professional.
Muscle Weakness
Vitamin D is important for muscle health and function. Deficiency can lead to muscle weakness, cramps or general muscle fatigue.
Older adults with vitamin D deficiency may also experience reduced mobility and increased risk of falls.
Frequent Illness or Infections
Vitamin D plays a key role in supporting the immune system. Individuals with low vitamin D levels may experience frequent colds, infections or slower recovery from illness.
Research suggests that adequate vitamin D levels help strengthen immune defenses against respiratory infections.
Mood Changes and Depression
Vitamin D may influence brain function and mood regulation. Some studies have found a connection between low vitamin D levels and mood disorders such as depression or anxiety.
People experiencing persistent mood changes should consider evaluating vitamin levels as part of a broader health assessment.
Hair Loss
Severe vitamin D deficiency may contribute to hair thinning or hair loss. While hair loss can have multiple causes, nutritional deficiencies including vitamin D deficiency may play a role.
Slow Wound Healing
Vitamin D contributes to the body’s inflammatory response and tissue repair processes. Individuals with deficiency may notice slower wound healing or delayed recovery from injuries.
Who Is at Risk of Vitamin D Deficiency?
Several factors can increase the risk of vitamin D deficiency.
Limited Sun Exposure
People who spend most of their time indoors or use strong sun protection regularly may not receive enough sunlight to produce sufficient vitamin D.
Urban lifestyles and indoor work environments contribute to this problem.
Older Adults
As people age, the skin becomes less efficient at producing vitamin D from sunlight. Older adults may therefore require additional dietary intake or supplements.
Individuals with Darker Skin
Melanin reduces the skin’s ability to produce vitamin D from sunlight. Individuals with darker skin tones may require longer sun exposure to produce adequate levels.
Poor Dietary Intake
Few foods naturally contain vitamin D. Diets lacking fortified foods, dairy products or fatty fish may contribute to deficiency.
Medical Conditions
Certain medical conditions such as kidney disease, liver disease or digestive disorders can affect vitamin D absorption and metabolism.
How Is Vitamin D Deficiency Diagnosed?
Vitamin D deficiency is diagnosed through a simple blood test that measures the level of 25-hydroxyvitamin D in the bloodstream.
Doctors may recommend testing for individuals who experience symptoms of deficiency or belong to high-risk groups.
Early diagnosis allows healthcare providers to recommend appropriate treatment and lifestyle adjustments.
How to Improve Vitamin D Levels
Sunlight Exposure
Regular sunlight exposure is one of the most effective ways to increase vitamin D levels. Experts generally recommend 10 to 30 minutes of sunlight exposure several times per week, depending on skin type and location.
Dietary Sources of Vitamin D
Although limited, certain foods contain vitamin D, including:
fatty fish such as salmon and mackerel
egg yolks
fortified milk and cereals
mushrooms
Including these foods in the diet can help maintain healthy vitamin D levels.
Vitamin D Supplements
In cases of significant deficiency, doctors may recommend vitamin D supplements. The dosage depends on the individual’s vitamin levels, age and health status.
It is important to take supplements under medical supervision to avoid excessive intake.
Preventing Vitamin D Deficiency
Maintaining adequate vitamin D levels requires a balanced combination of sunlight exposure, proper nutrition and regular health monitoring.
Routine health checkups and vitamin testing can help identify deficiencies early and prevent complications.
Adopting a healthy lifestyle with balanced nutrition and outdoor activity can significantly improve vitamin D status and overall health.
Conclusion
Vitamin D deficiency is a common but often overlooked health concern. Symptoms such as fatigue, bone pain, muscle weakness and frequent infections may indicate low vitamin D levels.
Early detection and proper management are essential to prevent long-term health complications. By ensuring adequate sunlight exposure, maintaining a balanced diet and undergoing regular health checkups, individuals can support healthy vitamin D levels and improve overall wellbeing.
Recognizing the warning signs of vitamin D deficiency and seeking timely medical advice can help protect long-term health and maintain optimal body function.
