Question: Are There Any Airborne Viruses?

Who is at risk for coronavirus?

People of all ages can be infected by the new coronavirus (COVID19).

Older people, and people with pre-existing medical conditions (such as obesity, asthma, diabetes, heart disease) appear to be more vulnerable to becoming severely ill with the virus.WHO advises people of all ages to take steps to protect themselves from the virus, for example by following good hand hygiene and good respiratory hygiene..

Is the coronavirus disease a pandemic?

COVID-19 can be characterized as a pandemic. This is due to the rapid increase in the number of cases outside China over the past 2 weeks that has affected a growing number of countries.

What is the risk of dying for the older people?

Over 95% of these deaths occurred in those older than 60 years. More than 50% of all fatalities involved people aged 80 years or older. Reports show that 8 out of 10 deaths are occurring in individuals with at least one comorbidity, in particular those with cardiovascular disease, hypertension and diabetes, but also with a range of other chronic underlying conditions.

Can drinking alcohol help in preventing COVID-19?

Alcohol does not protect against COVID-19; access should be restricted during lockdown.

How can I protect myself and others when using disinfectants?

Disinfectant solutions should always be prepared in well-ventilated areas. Wash your hands after using any disinfectant, including surface wipes. Keep lids tightly closed when not in use. Spills and accidents are more likely to happen when containers are open. Do not allow children to use disinfectant wipes. Keep cleaning fluids and disinfectants out of the reach of children and pets.Throw away disposable items like gloves and masks if they are used during cleaning. Do not clean and re-use.Do not use disinfectant wipes to clean hands or as baby wipes.

Can masks prevent the transmission of COVID-19?

See full answerMasks should be used as part of a comprehensive strategy of measures to suppress transmission and save lives; the use of a mask alone is not sufficient to provide an adequate level of protection against COVID-19.If COVID-19 is spreading in your community, stay safe by taking some simple precautions, such as physical distancing, wearing a mask, keeping rooms well ventilated, avoiding crowds, cleaning your hands, and coughing into a bent elbow or tissue. Check local advice where you live and work. Do it all!Make wearing a mask a normal part of being around other people. The appropriate use, storage and cleaning or disposal of masks are essential to make them as effective as possible.

How does the coronavirus disease spread?

The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water.

Can coronavirus spread through mosquito bite?

To date there has been no information nor evidence to suggest that the new coronavirus could be transmitted by mosquitoes. The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose. To protect yourself, clean your hands frequently with an alcohol-based hand rub or wash them with soap and water. Also, avoid close contact with anyone who is coughing and sneezing.

What is the meaning of airborne transmission?

Airborne transmission is defined as the spread of an infectious agent caused by the dissemination of droplet nuclei (aerosols) that remain infectious when suspended in air over long distances and time.

Can anyone be immune to coronavirus disease?

While many people globally have built up immunity to seasonal flu strains, COVID-19 is a new virus to which no one has immunity. That means more people are susceptible to infection, and some will suffer severe disease.

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 the elderly more vulnerable to the coronavirus disease?

The COVID-19 pandemic is impacting the global population in drastic ways. In many countries, older people are facing the most threats and challenges at this time. Although all age groups are at risk of contracting COVID-19, older people face significant risk of developing severe illness if they contract the disease due to physiological changes that come with ageing and potential underlying health conditions.

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.

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).

How dangerous is the coronavirus disease?

Although for most people COVID-19 causes only mild illness, it can make some people very ill. More rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such as high blood pressure, heart problems or diabetes) appear to be more vulnerable.

Can the coronavirus disease be transmitted in hot or humid climates?

From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.

Do vaccines against pneumonia protect against the coronavirus disease?

No. Vaccines against pneumonia, such as pneumococcal vaccine and Haemophilus influenza type B (Hib) vaccine, do not provide protection against the new coronavirus.The virus is so new and different that it needs its own vaccine. Researchers are trying to develop a vaccine against 2019-nCoV, and WHO is supporting their efforts.Although these vaccines are not effective against 2019-nCoV, vaccination against respiratory illnesses is highly recommended to protect your health.

Does COVID-19 survive in sewage?

While there is no evidence to date about survival of the COVID-19 virus in water or sewage, the virus is likely to become inactivated significantly faster than non-enveloped human enteric viruses with known waterborne transmission (such as adenoviruses, norovirus, rotavirus and hepatitis A).
