Nipah Virus: Everything about the virus


Kerala has been on high alert due to mysterious deaths of eight people because of an unidentified viral attack. Out of these, three were reported to be caused by Nipah Virus (NiV). As per the National Institute of Virology, Pune, Nipah Virus is the sole cause of these three deaths. Rajiv Sadanandan, Kerala’s health secretary, has assured that the government has started its preparation towards fewer deaths and that people should not panic. An unheard virus, NiV is yet to be understood by many. Here is what the virus is all about.

What is NiV?


As per the World Health Organisation (WHO), Nipah Virus is a newly emerging zoonosis that causes a severe disease in both animals and humans. This virus was first identified in Malaysia and Singapore in 1998. At that time, it was primarily caused in pigs and through them got transferred to humans. Nipah Virus infected as many as 265 people then, out of which 40 per cent were taken under intensive care due to the infection having spread severely. As quoted by the WHO, the natural host of the virus are fruit bats of the Pteropodidae Family, Pteropus genus.
The virus can be transferred through infected bats, pigs or humans who have been infected. In 2004, humans who consumed the date palm sap infected by fruit bats, caught the virus as well. Humans who were infected by other humans were reported in Bangladesh and India.

Signs and symptoms


Experts say that Nipah Virus is an airborne transmission infection and can affect those who come in direct contact with contaminated bodies.
Nipah Virus is usually associated with inflammation of the brain due to which severe days of fever can often lead to a state of confusion, disorientation and even persistent drowsiness. If not taken care of, these symptoms can even cause a coma in a span of 24-48 hours. There are many patients who show neurological, respiratory and pulmonary signs as well. Therefore, do not ignore any such signs.
Some common signs and symptoms of NiV are headache, fever, nausea, dizziness, drowsiness and mental issues such as confusion. These symptoms can last up to 7-10 days. Watching out for respiratory illness during the early stages is also a must.

Prevention and cure


As of now, there is no particular vaccine available purely for the treatment of Nipah Virus. The only way to treat this virus is through intensive supportive care. Since drinking raw date palm sap bitten by a bat can also cause NiV, it is safe to say that you should stay from consuming date palm for some time. Hospitals also need to raise awareness about symptoms and transmission to avoid human-to-human infections in such settings. Detection is another issue with NiV and anyone who feels the symptoms should get tested thoroughly from a recognized facility.

Avoiding direct contact with infected pigs, bats and humans in endemic regions should be practiced. Health professionals attending to such patients should take precautionary measures, such as wearing masks and gloves. If you feel uneasiness when in and around an infected region, get yourself tested immediately!

How to water recycle

Wastewater reuse On-site wastewater reuse can reduce water use in both urban and rural households. At present, most homes use potable (drinkable) water for practically everything in the house and garden. We are literally flushing our drinking water down the toilet! The articles Reducing water demand, Rainwater and Outdoor water use also have information on reducing potable water use. Opportunities to reuse wastewater and regulation of its treatment vary according to where you live. Urban households typically have a connection to a centralised, or reticulated, sewage system, whereas rural households manage their wastewater on site. Check with your local council or state health authority for advice on the regulations in your area. Two types of wastewater are created in a home: greywater and blackwater. Greywater is wastewater from non-toilet plumbing fixtures such as showers, basins and taps. Blackwater is water that has been mixed with waste from the toilet. Because of th...

Tips to ensure pure drinking water

Drinking contaminated water is the number one cause of illness and with the rise in the number of cases of monsoon diseases like cholera and typhoid, it is highly essential that you ensure you are drinking only pure water. During monsoons, the chances of contracting these diseases are higher as water gets contaminated due to water logging, unsanitary conditions, open sewage etc. Eating or drinking unhygienic food and water can transmit the virus easily into your system in turn making you sick. While basics like washing your hands properly before you eat and eating home-cooked meals to avoid infections are important, here are some tips to ensure you are drinking pure, clean water. The very first thing to keep in mind is to drink water that is boiled and filtered. Do not drink tap water as it isn’t potable (safe for drinking). When you go out, carry water from home instead of drinking outside water as you do not know if it is pure or not. If someone is ill...

ENVIRONMENTAL POLLUTION CONTROL AND PREVENTION

Image
Jerry Spiegel and Lucien Y. Maystre Over the course of the twentieth century, growing recognition of the environmental and public health impacts associated with anthropogenic activities (discussed in the chapter Environmental Health Hazards) has prompted the development and application of methods and technologies to reduce the effects of pollution. In this context, governments have adopted regulatory and other policy measures (discussed in the chapter Environmental Policy) to minimize negative effects and ensure that environmental quality standards are achieved. The objective of this chapter is to provide an orientation to the methods that are applied to control and prevent environmental pollution. The basic principles followed for eliminating negative impacts on the quality of water, air or land will be introduced; the shifting emphasis from control to prevention will be considered; and the limitations of building solutions for individual environmental media will be examined. It...
