As part of measures to prevent the outbreak of Lassa fever, the Tema Metropolitan Assembly (TMA) says it has gotten rid of 80 per cent rats, the carriers of the disease, from the community one market.

Lassa fever has claimed some 31 lives in Nigeria raising fears of a possible spread in the sub-region.

Head of Waste Management at the TMA, Solomon Noi, speaking to Class News said the assembly has put in place stringent measures to ensure the disease is prevented from entering Ghana.

He also noted that the sea port is one of the areas that requires attention considering the influx of goods and people.

He said: “Tema is a port city and for a port city, you see the ships travelling all over the world and docking at our place, so, we have to also intensify our operations around the harbour area. Our public safety department went to the community one market to [fumigate] and they got rid of about 80 per cent of the rodent that were causing havoc within the market area. In the same vein, we make sure we do not allow refuse to pile up within any part of the community and together with our private companies, the waste management providers, we ensure that on daily places we cart the refuse within our vicinities to the dump fill sites.”

The TMA’s action comes on the heels of a caution from the Deputy Director and Head of Surveillance at the Ghana Health Service (GHS), Dr Franklin Aseidu-Bekoe, to Ghanaians not to create an enabling environment for rats to invade their houses in the wake of the looming threat of Lassa fever outbreak.

Dr Aseidu-Bekoe speaking on the Executive Breakfast Show (EBS) on Class91.3FM on Monday, 12 February 2018, said although the disease is not in Ghana, keeping the environment clean will drive away rats, who are the carriers of the virus.

He told show host Moro Awudu that: “The virus stays in rodents [that is] rats, but the rat doesn’t show the disease but when the individual is exposed to the virus, you can get it. If you have left over food in your house and rats go and stay on it and pass urine or faeces and the individual goes to eat, you can be infected.

“Another way is when somebody is infected and you get into contact with fluids of the infected person you can also get it. So we get it from animal to man or man to man. This means that if you want to prevent the infection, let’s create a barrier. Do not allow rats to enter your house; do not create enabling environments for rats to enter your house. You get rats in your house when you have left over foods or unwashed utensils so you need to make sure you don’t create that enabling environment and also if you are exposed, make sure you are well protected and these are the methods you can use to prevent it”.

The GHS recommend the following to all health workers and institutions:

1. Surveillance on Lassa fever and Acute Haemorrhagic Fevers in general (using case definitions) should be enhanced.
2. Suspected cases of Lassa fever should be managed in specific isolation conditions
3. Health workers should adhere to regular Infection Prevention and Control (IPC) measures to prevent and protect against possible nosocomial transmission
4. Blood sample from suspected case(s) should be taken and safely packaged and sent to Noguchi Memorial Institute for Medical Research (NMIMR) for laboratory investigations
5. All levels (National, Regions, Districts and Facilities) are requested to update their preparedness and response plans for Lassa fever and VHF in general, sensitise the respective staff and create necessary public awareness.

GENERAL INFORMATION ON LASSA FEVER

Lassa fever is an Acute Viral Haemorrhagic Fever illness which is endemic in West Africa. The incubation period is 6-21 days. The onset of LF illness is often gradual, with non-specific signs and symptoms and commonly presents with fever, general weakness and malaise at the early onset. After a few days, headache, sore throat, muscle pain, chest pain, vomiting, diarrhoea and abdominal pain may follow. Severe cases may progress to show facial swelling, and bleeding tendencies (from mouth, nose, vagina or gastrointestinal tract, and low blood pressure. Shock, seizures, disorientation, and coma may be seen in the late stages. Complications include: deafness, transient hair loss and gait disturbance may occur during recovery. About 80 % of Lassa Fever infections are mild or asymptomatic.

• Lassa fever virus is transmitted to humans via contact with food or household items contaminated with the urine, saliva faeces, and blood of the rodent (Multi-mammate rat).
• Person-to-person infections and laboratory transmission can also occur, particularly in hospitals lacking adequate infection prevent and control measures.
• The disease is endemic in the rodent population in parts of West Africa and the multi-mammate rat serve as reservoir for the virus.
• Lassa fever is known to be endemic in Benin, Guinea, Liberia, Mali, Sierra Leone and parts of Nigeria, but probably exists in other West African countries as well.
• Ghana recorded first confirmed case(s) in 2011 and two districts, one each in Ashanti and Eastern regions then confirmed outbreaks of Lassa fever.
• Early use of Ribavarine (within seven days of disease onset), supportive care with re-hydration and symptomatic treatment improves survival.
• There is no effective vaccine for the disease at the moment.
