What Was The First Pandemic?

What is the definition of a pandemic?

A pandemic is defined as “an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people”.

The classical definition includes nothing about population immunity, virology or disease severity.

By this definition, pandemics can be said to occur annually in each of the temperate southern and northern hemispheres, given that seasonal epidemics cross international boundaries and affect a large number of people.

However, seasonal epidemics are not considered pandemics..

Are smokers more vulnerable to contracting COVID-19?

Tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

What are foods to avoid during the COVID-19 pandemic?

See full answerReduce foods such as red and fatty meats, butter and full-fat dairy products, palm oil, coconut oil, solid shortening and lard. Avoid trans fats as much as possible. Read nutrition labels to ensure that partially hydrogenated oils are not listed in the ingredients. If food labels are not available, avoid foods which commonly contain trans fats such as processed and fried foods, like doughnuts and baked goods – including biscuits, pie crusts, frozen pizzas, cookies, crackers and margarines that include partially hydrogenated fat.If in doubt, minimally processed foods and ingredients are better choices. Consume enough fibre Fibre contributes to a healthy digestive system and offers a prolonged feeling of fullness, which helps prevent overeating.

Will climate change make the COVID-19 pandemic worse?

See full answerThere is no evidence of a direct connection between climate change and the emergence or transmission of COVID-19 disease. As the disease is now well established in the human population, efforts should focus on reducing transmission and treating patients.However, climate change may indirectly affect the COVID-19 response, as it undermines environmental determinants of health, and places additional stress on health systems. More generally, most emerging infectious diseases, and almost all recent pandemics, originate in wildlife, and there is evidence that increasing human pressure on the natural environment may drive disease emergence. Strengthening health systems, improved surveillance of infectious disease in wildlife, livestock and humans, and greater protection of biodiversity and the natural environment, should reduce the risks of future outbreaks of other new diseases.

Can the coronavirus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.

What is social distancing during the COVID-19 pandemic?

Individuals may apply social distancing methods by staying at home, limiting travel, avoiding crowded areas, using no-contact greetings, and physically distancing themselves from others. Many governments are now mandating or recommending social distancing in regions affected by the outbreak.

Can smoking waterpipes spread the coronavirus disease?

Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

When was COVID-19 declared a pandemic?

The World Health Organization declared the outbreak a Public Health Emergency of International Concern on 30 January 2020, and a pandemic on 11 March 2020.

Fabric masks are recommended to prevent onward transmission in the general population in public areas, particularly where distancing is not possible, and in areas of community transmission. This could include the school grounds in some situations. Masks may help to protect others, because wearers may be infected before symptoms of illness appear. The policy on wearing a mask or face covering should be in line with national or local guidelines. Where used, masks should be worn, cared for and disposed of properly.

How do viruses get their name?

Viruses are named based on their genetic structure to facilitate the development of diagnostic tests, vaccines and medicines. Virologists and the wider scientific community do this work, so viruses are named by the International Committee on Taxonomy of Viruses (ICTV).

Is coronavirus disease zootonic?

All available evidence for COVID-19 suggests that SARS-CoV-2 has a zoonotic source.

How do I stay active in and around the home during the COVID-19 pandemic?

See full answerTry and reduce long periods of time spent sitting, whether for work, studying, watching TV, reading, or using social media or playing games using screens. Reduce sitting for long periods by taking short 3-5 minute breaks every 20-30 minutes. Simply stand up and stretch or even better, take a walk around the house, up and down the stairs, or into the garden. By just moving around and stretching you can improve your health and wellbeing. For more ideas and illustrations of healthy stretches see here.Set up a regular routine to be active every day, by planning a physical activity or exercise break either by yourself, by joining an online class, or by setting up a time to be active online with your friends or colleagues. Making a specific time to be active helps ensure you get your daily physical activity. Put the time in your diary, and it will help remind you.

Can the coronavirus disease spread through feces?

The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.
