Hypertension is a public health problem which has cut across all spheres of life and walks of life. From the literature review, the researcher has found that most hypertensive patients are less engaged in healthy behaviours because of knowledge deficit. The literature reviews also indicated that gender, age, level of education, lifestyle, and compliance to treatment regimen had significant association with healthy behaviours in patients with hypertension.

Lassa fever is a zoonotic disease caused by Lassa virus, which is a single-stranded RNA virus. Even though the virus was first described in the 1950s, it was not identified until 19691 and was subsequently named after a town in the present Borno state of Nigeria where the first case of the disease was recorded. The primary host of Lassa virus is a rodent of the genus. Mastomys, also referred to as ‘multimammate rat’. Once infected, Mastomys rats do not become ill but can shed the virus in their urine and faeces. Humans become infected from contact with the urine and faeces of infected rats. The infection can also occur in the process of hunting and processing rats for consumption. The virus is spread between humans through direct contact with blood, urine, faeces or other secretions from the infected person. As the world becomes increasingly connected, viral diseases, such as Lassa fever, once endemic to a region can be easily transmitted to other parts of the world, thus increasing the likelihood of a global pandemic. To reduce the probabilities of such events playing out, deliberate and concerted efforts must be applied towards both understanding Lassa fever and limiting infection rates. Therefore, measures that are limited in keeping of rodent out of homes and food supplies, as well as maintaining effective personal hygiene should be employed. Gloves, face masks, laboratory coats, and goggles are advised while in contact with an infected person.

Fire is a visible effect of the process of combustion as a special type of chemical reaction which occurs when oxygen in the atmosphere reacts with some sort of fuel to bring out flame.This review research extensively detailed the causes, preventive and protective measure to be taken to curb fire outbreak in the society. This showed that the best way to avoid fire outbreak is by adopting preventive and protective measure which includes avoidance of using phone in the kitchen,fueling generator when it is ON, smoking in flammable prone zone, gas leakage and so on. This paper will guide home users and fire preventive software designers to be aware of the things to be incurred or put in consideration when managing/designing/ implementing a device that can prevent or control fire outbreak. This research review will be of important to the world as it serves as a guide on fire outbreak causes and simple ways to prevent it both manually and automatically.
