Indonesia sudah mengesahkan satu kes virus Zika menjangkiti seorang lelaki di Jambi. Laporan oleh Menteri Kesihatan begitu pun menunjukkan keaadan masih terkawal.
Virus zika ini dibawa oleh nyamuk aedes.
Zika mempunyai tanda dan kesan seperti denggi dan kebanyakan orang boleh pulih sepenuhnya.
Tetapi yang lebih membimbangkan ialah virus ini boleh menyebabkan kecacatan otak kepada bayi jika ibunya dijangkiti.
Sehinggakan pakar-pakar di Brazil mencadangkan wanita di sana menangguhkan rancangan untuk mengandung.
Iklim Indonesia dan Malaysia sama juga seperti Brazil amat terdedah dengan bahaya virus zika.
Daripada sekarang Kerajaan dan rakyat Malaysia mesti mencegah dan mulakan perang pada peringkat yang lebih serius dengan nyamuk aedes.
Jangan jadi seperti Brazil. Kerajaannya dikecam hebat kerana lambat bertindak hingga virus zika sudah merebak luas.
The World Health Organization memberi amaran yang viurs zika merebak ganas di benua Amerika dan dijangkakan tiga hingga 4 juta kes tahun ini. Klik sini untuk press statement WHO.
Berikut adalah fakta mengenai virus Zika yang dipetik daripada laman WHO.
- Zika virus disease is caused by a virus transmitted by Aedes mosquitoes.
- People with Zika virus disease usually have a mild fever, skin rash (exanthema) and conjunctivitis. These symptoms normally last for 2-7 days.
- There is no specific treatment or vaccine currently available.
- The best form of prevention is protection against mosquito bites.
- The virus is known to circulate in Africa, the Americas, Asia and the Pacific.
Signs and Symptoms
The incubation period (the time from exposure to symptoms) of Zika virus disease is not clear, but is likely to be a few days. The symptoms are similar to other arbovirus infections such as dengue, and include fever, skin rashes, conjunctivitis, muscle and joint pain, malaise, and headache. These symptoms are usually mild and last for 2-7 days.
Recently in Brazil, local health authorities have observed an increase in Zika virus infections in the general public as well as an increase in babies born with microcephaly in northeast Brazil. Agencies investigating the Zika outbreaks are finding an increasing body of evidence about the link between Zika virus and microcephaly. However, more investigation is needed before we understand the relationship between microcephaly in babies and the Zika virus. Other potential causes are also being investigated.
Zika virus is transmitted to people through the bite of an infected mosquito from theAedes genus, mainly Aedes aegypti in tropical regions. This is the same mosquito that transmits dengue, chikungunya and yellow fever.
Zika virus is diagnosed through PCR (polymerase chain reaction) and virus isolation from blood samples. Diagnosis by serology can be difficult as the virus can cross-react with other flaviviruses such as dengue, West Nile and yellow fever.
Mosquitoes and their breeding sites pose a significant risk factor for Zika virus infection. Prevention and control relies on reducing mosquitoes through source reduction (removal and modification of breeding sites) and reducing contact between mosquitoes and people.
This can be done by using insect repellent; wearing clothes (preferably light-coloured) that cover as much of the body as possible; using physical barriers such as screens, closed doors and windows; and sleeping under mosquito nets. It is also important to empty, clean or cover containers that can hold water such as buckets, flower pots or tyres, so that places where mosquitoes can breed are removed.
Special attention and help should be given to those who may not be able to protect themselves adequately, such as young children, the sick or elderly.
During outbreaks, health authorities may advise that spraying of insecticides be carried out. Insecticides recommended by the WHO Pesticide Evaluation Scheme may also be used as larvicides to treat relatively large water containers.
Travellers should take the basic precautions described above to protect themselves from mosquito bites.
Zika virus disease is usually relatively mild and requires no specific treatment. People sick with Zika virus should get plenty of rest, drink enough fluids, and treat pain and fever with common medicines. If symptoms worsen, they should seek medical care and advice. There is currently no vaccine available.
