Biological weapons are microorganisms like virus, bacteria, fungi, or other toxins that are produced and released deliberately to cause disease and death in humans, animals or plants. 

Biological agents, like anthrax, botulinum toxin and plague can pose a difficult public health challenge causing large numbers of deaths in a short amount of time while being difficult to contain. Bioterrorism attacks could also result in an epidemic, for example if Ebola or Lassa viruses were used as the biological agents. 

Biological weapons is a subset of a larger class of weapons referred to as weapons of mass destruction, which also includes chemical, nuclear and radiological weapons. The use of biological agents is a serious problem, and the risk of using these agents in a bioterrorist attack is increasing

The novel coronavirus outbreak in 2019-2020 with nickname Covid-19 is a new strain of viruses which can cause fever, cough, breathing difficulties, pneumonia and even death in humans.To my notions it’s a kind of biological weapon which was used by a country for their own benefit.

The new coronavirus – Covid-19 – was first identified in Wuhan, China in December 2019. News reports say Wei Guixian was selling shrimp at the Huanan Seafood Market when she developed what she thought was a cold last DecemberWuhan Municipal Health Commission has confirmed that Wei was among the first 27 people to test positive for the coronavirus.The global outbreak of Covid-19 is still ongoing. The novel Coronavirus has affected more than 722087 people all over the world and has resulted in more than 33975 deaths.

The World Health Organization (WHO) has declared the coronavirus outbreak 2019–20 a Public Health Emergency of International Concern (PHEIC) initially, and later declared it as a pandemic.

Coronaviruses belong to a family of viruses called Coronaviridae and order Nidovirales. Coronaviruses get their name from their crown-like shape.

They are found in animals and birds and are zoonotic – as they are transmitted between animals and people.

Some types of coronavirus are dangerous for humans and result in severe diseases such as respiratory syndromes (MERS – Middle East Respiratory Syndrome and SARS – Severe Acute Respiratory Syndrome).

Coronavirus disease 2019 is an infectious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), a virus closely related to the SARS virus.

The 2019-nCov has been given the official name as COVID-19.

WHO declared Covid-19 infections as a public health emergency of international concern and later called it a pandemic.

Though the novel coronavirus is highly infectious and spreads rapidly, the death rate is low – only about 3.7%.

However, because of the possibility of a global-scale infection, all possible steps should be taken to prevent the fast spreading of the outbreak. Most people recover from the Covid-19 infection within 28 days, when proper supportive care is given.

Origin and TransmissionCoronaviruses originate in animals like camels and bats and are zoonotic diseases as it passes from animals to humans occasionally.

The source of a zoonotic disease is called reservoir species. (For SARS, the reservoir species was identified as bats).

The first known case of COVID-19 was reported in the Chinese city of Wuhan in December 2019 and was traced to an animal market in the city.

Research is ongoing on how COVID-19 spreads. However, as per WHO, the disease spreads in humans via exposure to respiratory secretions – the small droplets from the nose or mouth of an infected person – either directly or indirectly.

Compared to earlier outbreaks of SARS and MERS, COVID-19 has a greater global spread and researchers think that mutation in the virus strain is enabling it to be more efficiently transmitted.

Most people infected with the COVID-19 virus will experience mild to moderate respiratory illness and recover without requiring special treatment.  Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.

The best way to prevent and slow down transmission is be well informed about the COVID-19 virus, the disease it causes and how it spreads. Protect yourself and others from infection by washing your hands or using an alcohol based rub frequently and not touching your face. 

The COVID-19 virus spreads primarily through droplets of saliva or discharge from the nose when an infected person coughs or sneezes, so it’s important that you also practice respiratory etiquette .

Wash your hands frequently

Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.

Why? Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.

Maintain social distancing

Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.

Why? When someone coughs or sneezes they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person coughing has the disease.

Stay at home if you begin to feel unwell, even with mild symptoms such as headache and slight runny nose, until you recover.  Why? Avoiding contact with others and visits to medical facilities will allow these facilities to operate more effectively and help protect you and others from possible COVID-19 and other viruses.If you develop fever, cough and difficulty breathing, seek medical advice promptly as this may be due to a respiratory infection or other serious condition. Call in advance and tell your provider of any recent travel or contact with travelers.  Why? Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also help to prevent possible spread of COVID-19 and other viruses.
