Chikungunya and the eye: a review :
Most blood testing centres in the city are overloaded with blood samples as, to start the first line of treatment, the doctors need a proper blood report to distinguish the viral fever from dengue. Natural history of chikungunya fever Chikungunya fever is characterized by explosive outbreaks of epidemics followed by periods of disappearance sometimes lasting up to several decades.

Transmission of the virus The natural cycle of the virus is human-mosquito-human. There is, however, evidence of the existence of epizootic cycles that may retain the virus during the interepidemic period [ 1 , 4 , 5 , 17 ]. During epidemics, human beings serve as the Chikungunya virus reservoirs; during interepidemic periods, several vertebrates, such as monkeys, rodents, and birds, have been implied as the reservoir. Vertical maternal-fetal transmission has been documented in pregnant women affected by chikungunya fever [ 18 ].
Chikungunya virus infects the human cornea and can be transmitted via the corneal grafts [ 19 ]. The virus The virus causing chikungunya fever is an Alphavirus of the family Togaviridae whose genome consists of a linear, positive-sense, single-stranded RNA molecule, a to nm diameter capsid, and a phospholipid envelope [ 4 , 5 ].
Three lineages with distinct genotypic and antigenic characteristics have been identified from Chikungunya virus isolates collected from various geographical areas.
These include the West-African phylogroup, the East, Central, and Southern African phylogroup, and the Asian phylogroup [ 16 , 20 , 21 ].
This mutation is postulated to have facilitated the replication and transmission of the virus by reducing the cholesterol dependence of the virus [ 22 , 23 ]. The vector Chikungunya fever is transmitted by the bite of mosquitoes of the genus Aedes in the Asian region. Aedes aegypti is considered to be the principal vector, and Aedes albopictus Asian tiger mosquito has also recently emerged as an important vector. Adult mosquitoes rest in cool and shady areas and bite humans during daytime. Molecular mechanism The principal cell types infected by chikungunya are fibroblasts, epithelial cells, and lymphoid cells [ 25 ].
An antibody-dependent enhancement mechanism similar to that suggested for Dengue viruses [ 27 ] has also been implicated in the pathogenesis. Interferon gamma and IL levels have been observed to rise dramatically during the acute phase of chikungunya fever.
The level of IL returns to normalcy in patients who recover. In contrast, patients who develop chronic arthritis show persistently high IL levels. Histologic examination of synovia from patients with chronic arthritis following chikungunya fever has revealed joint inflammation due to macrophages containing viral material.
Metalloprotease MMP2 also contributes to tissue damage. Chikungunya virus leads to apoptosis through both the intrinsic and extrinsic pathway [ 28 ]. Rarely the patient suffering from dengue may develop shock, then it is called dengue shock syndrome DSS. Steps To Prevent Dengue Prevention is basically by: Avoiding mosquito bites by using mosquito repellents Eliminating pockets of stagnant water that serve as mosquito breeding sites at home, workplaces and their vicinity, Not storing water in open containers.
Covering all water containers with lids. Preventing mosquito entry by keeping doors closed and windows screened. Wearing protective clothing like long-sleeved shirts, long pants, socks and shoes when outdoors. Using mosquito nets at home. Scrubbing and cleaning margins of containers used for water to dislodge the eggs of Aedes aegypti Covering overhead tank to prevent access to mosquitoes. Aedes mosquitoes usually bite during the day; therefore, special precautions should be taken during early morning hours before day break and in the late afternoon before dark.
Some facts about Dengue Fever: What are the types of dengue? There are four types of dengue viruses that cause dengue fever worldwide.
These types are Dengue 1, 2, 3 and 4. The two principal illnesses that dengue virus causes are: How can someone get dengue fever?
Dengue fever occurs following the bite of an infected mosquito Aedes aegypti. This type of mosquito has a peculiar white spotted body and legs and is easy to recognize even by laymen.
It breeds in clean water see Question 20 and has a flight range of only — metres. The mosquito gets the Dengue virus after biting a human being infected with dengue virus. What is the difference between suspected and probable case of dengue?
If a patient suspected to be having dengue has reduced platelets or an increase in blood haematocrit, then the patient has probable dengue. These additional findings makes dengue more likely. Patients with dengue may not have a high haematocrit if the person was anaemic to start with. Can dengue fever become dangerous? The infection can become dangerous since it may cause damage to the blood vessels. The symptoms and signs of dengue haemorrhagic fever and dengue shock syndrome are related to damage to the blood vessels and derangement in functioning in components of blood that help it to clot.
Can people die from dengue fever? People who suffer from dengue fever have no risk of death but some of them develop Dengue Haemorrhagic Fever or Dengue Shock Syndrome. In some of these cases death can occur. With proper treatment, the patients with Dengue haemorrhagic fever and dengue shock syndrome can recover fully.
Good treatment provided in time can save most lives. Can you get dengue again after suffering from it once? It is possible to get dengue more than once. Dengue can occur because of 4 different but related strains of dengue virus. If a person has suffered from one virus, there can be a repeat occurrence of dengue if a different strain is involved subsequently.
Being affected by one strain offers no protection against the others. The risk of dengue haemorrhagic fever increases if you contract dengue more than once. What is dengue haemorrhagic fever? Dengue haemorrhagic fever is a severe complication of the dengue virus. It is most commonly seen in children aged under 15 years but can occur in adults. It is more likely to occur if you have contracted dengue before. Symptoms for dengue haemorrhagic fever are the same as for dengue fever, but days after the onset of fever, patients show a rapid deterioration in their condition.
Cardiovascular disease, shock and sometimes death may follow. Can I get dengue fever from another person? Dengue does not spread directly from person to person. It is only spread through the bite of an infected mosquito.
When does dengue develop after getting the infection? After the entry of the virus in the person, it multiplies in the lymph glands in the body.
