Every year has something unique and different about it compared to the previous. In my opinion 2016 will probably be the year forever linked to the Zika virus. Although the virus was discovered decades ago,its immense media coverage means it has become a global talking point.   But what do we really know about Zika? Below is our top 10 Zika Q&As.

What is the Zika virus?

The Zika virus is an infection transmitted by mosquitoes and was first discovered in the Zika forest in Uganda in 1947.

If it was discovered decades ago, why are only talking about it now?

It’s a fairly common virus in parts of Africa and Asia but it became more widespread from May 2015 after an outbreak in Brazil.

So how many people have it now?

Literally millions of people have been infected by the virus particularly in South and Central America and the Caribbean.

That’s a lot of people! How does the virus affect them?

If you are infected by the virus the symptoms you can expect include: a mild fever, joint pain, itching, rash, conjunctivitis, headache and eye pain. The symptoms are usually mild lasting no longer than 7 days. However, many people infected by the virus don’t experience any symptoms at all.

That doesn’t sound too bad so remind me of why Zika seems so scary?

It’s a concern for pregnant women, as it’s been linked to a birth defect known as microcephaly(pronounced micro-sef-alee). A person with this defect has an abnormally small head and potential bran damage. There is some evidence that babies born to women who have been infected with the Zika virus are more likely to have microcephaly.

So what exactly can we do about this? People travel to those parts of the world all the time.

If you would like to travel to areas affected by the Zika outbreak it’s best to seek advice before your trip from a healthcare professional. If you are pregnant or actively trying to become pregnant and have recently returned from those regions – a trip to your GP is recommended. Although you can reduce your risk of catching the virus in the high risk regions by using insect repellent and covering your limbs with long loose clothing, you may prefer to avoid the risk by not visiting these areas if you are already pregnant or trying to become so.

You have mentioned the mothers but what about potential fathers? Can they transmit Zika to their partners and subsequently to an unborn baby?

There is a very low risk that the Zika virus may be transmitted through sexual intercourse. The recommendations are: if a partner has travelled to a country with a Zika virus outbreak, the couple should use barrier contraception (a condom) for 28 days following his return, whether he has Zika or not.If he begins to experience Zika symptoms or is diagnosed with a Zika virus infection by a doctor, the couple should use condoms for 6 months.

What if I have been to one of those countries and now want to try for a baby?

In the first instance, see your GP or midwife and tell them the name of the country/region you have just returned from. You should do this whether you have symptoms or not. The guidance also states that you should wait for at least 28 days following your returnhome before you try to become pregnant( evenif you have no symptoms). If you have developed any symptoms which remotely resemble the Zika symptoms(within two weeks of returning home) then it is recommended that you wait at least six months after a complete recovery before trying for a baby.

 I know someone who is pregnant and she has just returned from there!  What should she do?

She should make an appointment with her midwife or doctor as soon as possible. But tell your friend that although there is an increased risk of the birth defect, not everyone who has been pregnant in a Zika outbreak region has had a baby with microcephaly.

If you have friends and family in the Caribbean you have probably been hearing the word “chikungunya” a lot lately and might even know someone who has had this disease. You may be wondering: ‘what exactly is chikungunya?’ and ‘where did it suddenly come from?’  In this week’s blog we’ll tell you everything you need to know about this disease.

What is Chikungunya?

Chikungunya is an illness that is caused by a virus and  it is spread through the bite of an infected female mosquito. It causes fever, joint pain, headaches and muscle pain. It is not usually a deadly disease with most patients recovering within a week but some people may develop long-term joint pain.

The History of Chikungunya

The Chikungunya VirusThe chikungunya virus is thought to have originated in central or east Africa where scientists believe it circulated in forest-dwelling mosquitos and non-human primates. The disease first appeared in humans in 1952 in the Makonde Plateau which is the border area between Mozambique and Tanzania. The name chikungunay is a Makonde word that means “that which bends up” and refers to the posture of those who develop the symptoms of this illness.

Since making its debut in 1952 there have been regular small outbreaks of chikungunya in Africa, but between 1999 and 2000 there was a large outbreak in the Democratic Republic of Congo and another one in Gabon in 2007.

In 2005, a chikungunya outbreak was reported in the Reunion Islands in the Indian Ocean where it affected over 200,000 people. It soon moved to India and several South East Asian countries over the next two years affecting Indonesia, Thailand, Maldives and Myanmar, and then appeared for the first time in Europe in a small outbreak in north eastern Italy in 2007.

The Current Chikungunya Outbreak

The current outbreak of chikungunya, which is affecting the Caribbean, began in December 2013 with the first case detected in St Martin. As of 10^th October 2014 34 countries in the Caribbean and Central, South and North America have been affected; a total of 748,403 suspected cases have been reported.

 

 

 

How Does Chikungunya Spread?

Chikungunya is transmitted from human to human via the bites of infected female mosquitoes. Firstly a mosquito feeds on the blood of an infected person and acquires the virus. The virus then incubates inside the mosquito for 10 days before it can be transmitted to another human via the bite of the mosquito.

The species of mosquito that can transmit chikungunya are the Aedes aegypti and Aedes albopictus mosquitoes. They tend to bite during the day time, mostly in the early morning and late afternoon.

Chikungunya is rarely transmitted from mother to new-born child and it could be transmitted through a blood transfusion but there has been no evidence of this happening.

Symptoms 

The symptoms of chikungunya appear 3-7 days after a person has been bitten by an infected mosquito.  The most common symptoms are: fever and severe joint pain. Other symptoms include headache, muscle pain, swelling of the joints, nausea, fatigue and a rash. Most patients recover fully  within a few weeks but in some patients joint pain may last for months or years.

How Can I Protect Myself?

If you live in or are visiting a country affected by chikungunya the only way to protect yourself is to avoid being bitten by mosquitoes and the best way to do this is to:

1. Wear long sleeves, trousers and hats (if needed) to protect unexposed skin especially during the day when mosquitoes are most likely to bite

2. Use appropriate insect repellent. It is recommended that you use insect repellents that contain DEET, Picardin, oil of lemon eucalyptus (OLE), PMD or IR3535. Follow the directions on the repellent packaging, reapply as directed and make sure you exercise care when applying on children.

3.When using sun screen, apply your sun screen first then the insect repellent

4. Clear your  home and office of mosquitoes by spraying with a bug spray, close all doors and windows and then use air-conditioning, or install mosquito nets on doors and windows to prevent mosquitoes coming indoors

5. Empty standing water from outdoor containers as these breed mosquitoes

If you think you might have been infected with chikungunya, keep an eye on your health and if you develop any symptoms please do visit your doctor.

Treatment

Currently there is no treatment or vaccination for chikungunya, doctors simply treat the symptoms and may give patients ibuprofen or paracetamol to combat fever and pain. It is advised that you get plenty of rest and drink lots of fluids to prevent dehydration.

If you’ve recently been to the Caribbean follow the advice given in the infographic below.

That, in a nutshell, is what you need to know about chikungunya. For more information you can visit the CDC’s website.
